Display ASCII Value in C

In this program, we will find ASCII value in C. C program to display the decimal value or ASCII value of a character. C program to find ASCII value in a given Range.

Prerequisites for writing all below programs:-

ASCII stands for American Standard Code for Information Interchange. ASCII was developed by the ANSI (American National Standards Institute). ASCII is used to interchange the information from a high-level language to low-level language. Machine or Computer understand only binary languages. So, the character data type represents integers.

#include<stdio.h>
int main()
{
     char ch;

     printf("Enter any character: ");
     scanf("%c",&ch);

     printf("ASCII value of %c is = %d",ch,ch);

     return 0;
}

Output:-

Enter any character: S
ASCII value of S is = 83

Q) Display the decimal value or ASCII value in C of selected characters such as ‘A’, ‘a’, ‘0’, ‘l’, ‘K’, ‘z’, ‘Z’, ‘\0’, ‘\n’, ‘\t’.

Find ASCII value in C in a given Range

#include<stdio.h>
int main()
{
     int i, j; //i and j are two variables to store Range data
     int k;

     printf("Enter Range (i and j value such that i<j): ");
     scanf("%d %d",&i, &j);

     for(k=i; k<=j; k++)
     {
       printf("ASCII value of %d is= %c\n", k, k);
     }

     return 0;
}

Output:-
