C program to print ASCII values using while loop.

By: IncludeHelp, On 17 OCT 2016

In this program we will learn how to print ASCII value along with the characters using while loop in c programming language?

Here we will print ASCII value along with the related characters from 32 to 127 using while loop, we will assign 32 to loop counter and run a loop until value will not be 127.

C program (Code Snippet) - Print ASCII of all characters using while loop

Let’s consider the following example:

/*c program to print ascii values using while loop*/

#include <stdio.h>

int main(){
	unsigned char ch;		
	
	ch=32; //start with 32 (space)
	while(ch<=127){
		printf("%c [%03d] ",ch,ch);
		ch++;
	}
	printf("\n");
	
	return 0;
}

Output

      [032] ! [033] " [034] # [035] $ [036] % [037] & [038] ' [039] ( [040] ) [041] * [042] + [043] , [044] - [045] . [046] / [047] 0 [048] 1 [049] 2 [050] 3 [051] 4 [052] 5 [053]
