ASCII value in C Language

What is ASCII ?

The full form of ASCII is American Standard Code for Information Interchange. It is a character encoding scheme used for electronic communications. Each character or special character is represented by some ASCII code, and each ASCII code occupies 7 bits in memory.

In the C programming language, the character variable contains the ascii value of the character variable, not the character value itself. ASCII values ​​represent variable characters as numbers, and each variable character is assigned a number between 0 and 127. For example, the ascii value of ‘A’ is 65.

In the above example, we have assigned ‘A’ to a character variable with ascii value 65, so 65 and not ‘A’ will be stored in the character variable.

Syntax

To get the ASCII value of a character in C, you can use an int file to store the ASCII value and the character itself must be enclosed in an expression. For example:

char ch = ‘A’;     // Character variable

int ascii_value;   // Variable to store ASCII value

ascii_value = ch;  // Assigning ASCII value to variable

 

• To print the ASCII value, you can use the printf() function with the %d format specifier:

printf(“ASCII value of %c is %d\n”, ch, ascii_value);

 

Example

Here is a complete example showing how to get and print the ASCII value of a character.

#include <stdio.h>

int main() {

char ch = ‘A’;     // Character variable

int ascii_value;   // Variable to store ASCII value

ascii_value = ch;  // Assigning ASCII value to variable

printf(“ASCII value of %c is %d\n”, ch, ascii_value);

return 0;

}

Output

ASCII value of A is 65
