C Program to print all ASCII values.

Problem

Print the American Standard Code for Information Interchange (ASCII) values of 0 to 255 characters without initializing the character to integer type variable. Simply, use the format specifier.

Solution

Here we are writing a program to print only from 65 to 122.

If you want to see all ASCII values, in for loop you can write as follows −

For(i=0;i<255;i++)

Then, it prints all the ASCII values from 0 to 255.

The logic used to print the ASCII values from 65 to 122 is as follows −

Prints ASII values From A to z
for (i = 65; i < =122; i++){
   printf("%c \t\t %d\n", i, i);
}

Example

Following is the C program to print the ASCII values from 65 to 122 −

#include <stdio.h>
int main() {
   // Declare Variables
   int i = 0;
   printf("Character \t ASCII Value\n\n");
   //Print ASCII Values
   for (i = 65; i <=122; i++) {
      printf("%c \t\t %d\n", i, i);
   }
   return 0;
}

Output

When the above program is executed, it produces the following output −
