Basic Concepts of C Programming
Now that you know what Aikman Series C.pdfl is, why learning C programming is beneficial, and how to download and use Aikman Series C.pdfl, let's dive into the basic concepts of C programming. In this section, we will cover four topics: data types and variables, operators and expressions, input and output, and control structures.
Data types and variables
Data types are the categories of data that can be stored and manipulated in a program. They define the size, range, and format of the data. Variables are the names given to the memory locations that store the data. They allow us to access and modify the data easily.
In C programming, there are two types of data types: primitive and derived. Primitive data types are the basic data types that are built into the language. They include:
char: a single character (1 byte)
int: an integer number (2 or 4 bytes)
float: a floating-point number (4 bytes)
double: a double-precision floating-point number (8 bytes)
void: no value (0 bytes)
Derived data types are the data types that are derived from the primitive data types. They include:
array: a collection of elements of the same data type
pointer: a variable that stores the address of another variable
structure: a collection of elements of different data types
union: a collection of elements of different data types that share the same memory space
enumeration: a set of named constants
function: a block of code that performs a specific task
To declare a variable in C programming, we use the following syntax:
```c data_type variable_name; ``` For example:
```c int age; char name[20]; float height; ``` To assign a value to a variable in C programming, we use the following syntax:
```c variable_name = value; ``` For example:
```c age = 25; name = "John"; height = 1.75; ``` Operators and expressions
Operators are the symbols that perform operations on operands (values or variables). Expressions are the combinations of operators and operands that produce a result.
In C programming, there are several types of operators:
Arithmetic operators: perform arithmetic operations such as addition (+), subtraction (-), multiplication (*), division (/), modulus (%), increment (++), and decrement (--).
Relational operators: compare two operands and return a boolean value (true or false) such as equal to (==), not equal to (!=), greater than (>), less than (=), and less than or equal to (<=).
Input and output
Input and output are the processes of getting data from the user and displaying data to the user. In C programming, we use the standard input/output library (stdio.h) to perform input and output operations.
The most common functions for input and output in C programming are:
printf(): prints formatted data to the standard output (screen)
scanf(): reads formatted data from the standard input (keyboard)
putchar(): prints a single character to the standard output
getchar(): reads a single character from the standard input
fopen(): opens a file for reading or writing
fclose(): closes a file
fread(): reads data from a file
fwrite(): writes data to a file
fseek(): moves the file pointer to a specified position
ftell(): returns the current position of the file pointer
To use these functions, we need to include the stdio.h header file at the beginning of our program:
```c #include
``` Here are some examples of using these functions:
```c // print "Hello, world!" to the screen printf("Hello, world!\n"); // read an integer from the keyboard and store it in x scanf("%d", &x); // print "A" to the screen putchar('A'); // read a character from the keyboard and store it in c c = getchar(); // open a file named "data.txt" for writing FILE *fp = fopen("data.txt", "w"); // close the file fclose(fp); // write "Hello" to the file fwrite("Hello", 1, 5, fp); // read 5 bytes from the file and store them in buffer fread(buffer, 1, 5, fp); // move the file pointer to the beginning of the file fseek(fp, 0, SEEK_SET); // get the current position of the file pointer long pos = ftell(fp); ``` Control structures
Control structures are the statements that control the flow of execution of a program. They allow us to make decisions, repeat actions, and jump to different parts of the code.
In C programming, there are three types of control structures:
Selection statements: choose one of several alternatives based on a condition. They include if, if-else, if-else-if, and switch-case.
Iteration statements: execute a block of code repeatedly until a condition is met. They include while, do-while, and for.
Jump statements: transfer control to another part of the code. They include break, continue, return, and goto.
Here are some examples of using these statements:
```c // if statement: print "Positive" if x is positive if (x > 0) printf("Positive\n"); // if-else statement: print "Odd" or "Even" depending on x if (x % 2 == 0) printf("Even\n"); else printf("Odd\n"); // if-else-if statement: print "A", "B", "C", or "D" depending on x if (x >= 90) printf("A\n"); else if (x >= 80) printf("B\n"); else if (x >= 70) printf("C\n"); else printf("D\n"); // switch-case statement: print "One", "Two", "Three", or "Other" depending on x switch (x) case 1: printf("One\n"); break; case 2: printf("Two\n"); break; case 3: printf("Three\n"); break; default: printf("Other\n"); // while statement: print x while x is less than 10 while (x < 10) printf("%d\n", x); x++; // do-while statement: print x at least once and then while x is less than 10 do printf("%d\n", x); x++; while (x < 10); // for statement: print x from 0 to 9 for (x = 0; x < 10; x++) printf("%d\n", x); // break statement: exit the loop when x is 5 for (x = 0; x < 10; x++) if (x == 5) break; printf("%d\n", x); // continue statement: skip the current iteration when x is 5 for (x = 0; x < 10; x++) if (x == 5) continue; printf("%d\n", x); // return statement: return the value of x from a function int square(int x) return x * x; // goto statement: jump to the label "end" when x is 5 for (x = 0; x < 10; x++) if (x == 5) goto end; printf("%d\n", x); end: printf("End of loop\n"); Advanced Topics of C Programming
After learning the basic concepts of C programming, you are ready to explore some of the advanced topics of C programming. In this section, we will cover five topics: arrays and strings, functions and recursion, pointers and dynamic memory allocation, structures and unions, and file handling and preprocessor directives.
Arrays and strings
Arrays are derived data types that store a collection of elements of the same data type in a contiguous memory location. They allow us to access and manipulate multiple values using a single variable name and an index.
To declare an array in C programming, we use the following syntax:
```c data_type array_name[size]; ``` For example:
```c int numbers[10]; char letters[26]; ``` To assign values to an array in C programming, we use the following syntax:
```c array_name[index] = value; ``` For example:
```c numbers[0] = 10; letters[25] = 'Z'; ``` To access values from an array in C programming, we use the following syntax:
```c value = array_name[index]; ``` For example:
```c x = numbers[0]; y = letters[25]; ``` Strings are derived data types that store a sequence of characters terminated by a null character ('\0'). They are essentially arrays of char type. They allow us to store and manipulate text data.
To declare a string in C programming, we use the following syntax:
```c char string_name[size]; ``` For example:
```c char name[20]; char message[100]; ``` To assign values to a string in C programming, we use the following syntax:
```c string_name = "value"; ``` For example:
```c name = "John"; message = "Hello, world!"; ``` To access values from a string in C programming, we use the same syntax as for arrays:
```c value = string_name[index]; ``` For example:
```c x = name[0]; y = message[6]; ``` Functions and recursion
Functions are derived data types that store a block of code that performs a specific task. They allow us to modularize our program into smaller and reusable units. They also help us to avoid code duplication and improve readability.
To define a function in C programming, we use the following syntax:
```c return_type function_name(parameter_list) // function body ``` For example:
```c int add(int x, int y) // function body return x + y; ``` To call a function in C programming, we use the following syntax:
```c function_name(argument_list); ``` For example:
```c add(10, 20); ``` Recursion is a technique of defining a function in terms of itself. It allows us to solve complex problems by breaking them down into simpler subproblems. It also helps us to implement algorithms that are based on recursion, such as binary search, merge sort, factorial, Fibonacci, etc.
To write a recursive function in C programming, we need to have two parts: a base case and a recursive case. The base case is the simplest case that can be solved directly. The recursive case is the case that can be reduced to a smaller or simpler subproblem by calling the same function.
For example:
```c // recursive function to calculate the factorial of n int factorial(int n) Pointers and dynamic memory allocation
Pointers are derived data types that store the address of another variable. They allow us to access and modify the value of a variable indirectly. They also help us to create dynamic data structures, such as linked lists, trees, graphs, etc.
To declare a pointer in C programming, we use the following syntax:
```c data_type *pointer_name; ``` For example:
```c int *p; char *q; ``` To assign an address to a pointer in C programming, we use the following syntax:
```c pointer_name = &variable_name; ``` For example:
```c p = &x; q = &y; ``` To access the value of a variable using a pointer in C programming, we use the following syntax:
```c value = *pointer_name; ``` For example:
```c x = *p; y = *q; ``` Dynamic memory allocation is a technique of allocating memory at run time. It allows us to create variables and data structures that have variable size and lifetime. It also helps us to optimize the memory usage and performance of our program.
To perform dynamic memory allocation in C programming, we use the following functions from the standard library (stdlib.h):
malloc(): allocates a block of memory of a given size and returns a pointer to it
calloc(): allocates a block of memory for an array of a given number and size of elements and returns a pointer to it
realloc(): reallocates a block of memory to a new size and returns a pointer to it
free(): frees a block of memory that was previously allocated
To use these functions, we need to include the stdlib.h header file at the beginning of our program:
```c #include
``` Here are some examples of using these functions:
```c // allocate 10 bytes of memory and store the pointer in p p = malloc(10); // allocate 20 bytes of memory for an array of 5 integers and store the pointer in q q = calloc(5, sizeof(int)); // reallocate the memory pointed by p to 15 bytes and store the pointer in p p = realloc(p, 15); // free the memory pointed by p free(p); // free the memory pointed by q free(q); ``` Structures and unions
Structures and unions are derived data types that store a collection of elements of different data types. They allow us to group related data into a single unit. They also help us to create user-defined data types that suit our needs.
To define a structure or a union in C programming, we use the following syntax:
```c struct structure_name // structure members ; union union_name // union members ; ``` For example:
```c struct student int id; char name[20]; float marks; ; union data int x; char y; float z; ; ``` The difference between structures and unions is that structures allocate separate memory for each member, while unions allocate shared memory for all members. This means that structures can store different values for each member at the same time, while unions can only store one value for one member at a time.
To declare a variable of structure or union type in C programming, we use the following syntax:
```c struct structure_name variable_name; union union_name variable_name; ``` For example:
```c struct student s1; union data d1; ``` To assign values to a structure or union variable in C programming, we use the following syntax:
```c variable_name.member_name = value; ``` For example:
```c s1.id = 101; s1.name = "Alice"; s1.marks = 95.5; d1.x = 10; d1.y = 'A'; d1.z = 3.14; ``` To access values from a structure or union variable in C programming, we use the same syntax as for assignment:
```c value = variable_name.member_name; ``` For example:
```c x = s1.id; y = s1.name; z = s1.marks; x = d1.x; y = d1.y; z = d1.z; ``` File handling and preprocessor directives
File handling is the process of creating, reading, writing, and manipulating files in a program. It allows us to store and retrieve data permanently and efficiently. It also helps us to exchange data between different programs and devices.
To perform file handling in C programming, we use the functions from the standard input/output library (stdio.h) that we have already seen in the previous section: fopen(), fclose(), fread(), fwrite(), fseek(), and ftell(). We also use some new functions, such as fprintf(), fscanf(), fgetc(), fputc(), fgets(), and fputs().
Here are some examples of using these functions:
```c // open a file named "data.txt" for reading FILE *fp = fopen("data.txt", "r"); // close the file fclose(fp); // write "Hello" to the file using fprintf() fprintf(fp, "Hello\n"); // read a string from the file using fscanf() fscanf(fp, "%s", buffer); // write a character 'A' to the file using fputc() fputc('A', fp); // read a character from the file using fgetc() c = fgetc(fp); // write a string "World" to the file using fputs() fputs("World\n", fp); // read a line from the file using fgets() fgets(buffer, 100, fp); ``` Preprocessor directives are the commands that are executed by the preprocessor before the compilation of the program. They allow us to modify the source code, include other files, define macros, and control conditional compilation.
