C Program to Print ASCII Value of a Character

In this tutorial, we will write a program to print ASCII value of a character in C programming. Before that, you should have knowledge on the following topic in C.

• data type in C

ASCII stands for American Standard Code for Information Interchange. It is a 7-bit character set that contains 128 (0 to 127) characters. It represents the numerical value of a character.

Example: ASCII value for character A is 65, B is 66 and a is 97, b is 98, and so on.

C Program to Print ASCII Value of a Character

#include <stdio.h>
#include <conio.h>

int main()
{
  char ch;
  printf("Enter a Character: ");
  scanf("%c", &ch);

  printf("Its ASCII Value: %d", ch);

  getch();
  return 0;
}

Output:

Enter a Character: A
Its ASCII Value: 65

C Program to print ASCII value of all Characters

Source Code: Print the ASCII value of all the characters in C.

#include <stdio.h>
#include <conio.h>

int main()
{
  int i;
  printf("ASCII Value of all the Characters.\n");

  for (i = 0; i < 255; i++)
    printf("ASCII value of %c: %i\n", i, i);

  getch();
  return 0;
}

Output: You will get the list of all the characters starting from 0 to 255 on the output display screen.
