ASCII value in C language

What is ASCII code?

The full form of ASCII is the American Standard Code for information interchange. It is a character encoding scheme used for electronics communication. 
Each character or a special character is represented by some ASCII code, and each ascii code occupies 7 bits in memory.

C Programming Language, a character variable does not contain a character value itself rather the ascii value of the character variable. 

The ascii value represents the character variable in numbers, and each character variable is assigned with some number range from 0 to 127. 

For example

The ascii value of 'A' is 65.

We create a program which will display the ascii value of the character variable.

#include <stdio.h>  

int main()  

{  

    char c;     

    printf("Enter a character");  

    scanf("%c",&c); 

    printf("\n The ascii value of the c variable is  %c = %d",  c, c);  

    return 0;  

}  

Output:

Enter a character G

The ascii value of the c variable is 71
