ASCII Table in C

 The ASCII (American Standard Code for Information Interchange) table represents a character encoding standard for digital communication.

 In C, you can print the ASCII table using loops to display characters and their corresponding ASCII values.

 Program to Print ASCII Table with Decimal Values

#include<stdio.h> 

int main() {
    int i;

    printf("ASCII Table with Decimal Values:\n");
    for(i = 0; i <= 130; i++) {
        printf("%d: %c\n", i, i);
    }

    return 0;
}

Program 1: Prints the ASCII table with decimal values ranging from 0 to 130.

Program 2: Prints the ASCII table with hexadecimal values. The format specifier %x is used to print in hexadecimal.

Program 3: Prints the ASCII table with octal values. The format specifier %o is used to print in octal.

In each program, a for loop iterates from 0 to 130,  printing each ASCII value along with its corresponding character.
