Introduction of C programming language

-
C is a general-purpose programming language that has been around for nearly 50 years.
C has been used to write everything from operating systems (including Windows and many others) to complex programs like the Python interpreter, Git, Oracle database, and more.
The versatility of C is by design. It is a low-level language that relates closely to the way machines work while still being easy to learn.

Addition 2 number in C Language

Image
Sample Program : Addition of two numbers Consider the program, which performs addition on two numbers and displays the result. The program is following : This program when executed will product the following output : 100 106.10 The first two lines of the program are comment lines. It is a good practice to use comment lines in the beginning to give information such as name of the program, author, date etc. Comment characters are also used in other lines to indicate line numbers. The words number and amount are variable names that are used to store numeric data. The numeric data may be either in integer form or in real form. In C, all variables should be declared to tell the compiler what the variable names are and what type of data they hold. The variables must be declared before they are used. In lines 5 and 6, the declarations : int number; float amount; tell the compiler that number is an integer( int ) and amount is a floating( float...

Input and Output in C

-
Input : C supports a number of ways for taking user input. getchar() Returns the value of the next single character input. For example : #include <stdio.h> int main()  {   char a = getchar();   printf("You entered: %c", a);   return 0; } The input is stored in the variable a. The gets() function is used to read input as an ordered sequence of characters, also called a string. A string is stored in a char array. For example :  #include <stdio.h> int main()  {   char a[100];   gets(a);   printf("You entered: %s", a);   return 0; } Here we stored the input in an array of 100 characters. scanf() scans input that matches format specifiers. For example : #include <stdio.h> int main()  {   int a;   printf("Please enter an element : ", a);   scanf("%d", &a);    return 0; } The " &" sign before the variable name is th...

Comments in C

-
Comments : Comments are explanatory information that you can include in a program to benefit the reader of your code. The compiler ignores comments, so they have no affect on a program. A comment starts with a slash asterisk /* and ends with an asterisk slash */ and can be anywhere in your code. Comments can be on the same line as a statement, or they can span several lines. For example: #include <stdio.h> /* A simple C program  * Version 1.0  */ int main() {   /* Output a string */   printf("Hello World!");   return 0; } Note :  As you can see, comments clarify the program's intent to the reader. Use comments to clarify the purpose and logic behind segments of code. Single-line Comments :  C++ introduced a double slash comment // as a way to comment single lines. Some C compilers also support this comment style. For example:  #include <stdio.h> int main() {   int x = 42; //int for a who...
