C Program to find ASCII Value of Total Characters in a String

In this article, we will show you, How to write a C Program to find ASCII Value of Total Characters in a String using For loop, and while loop with practical example.

C Program to find ASCII Value of Total Characters in a String Example 1

This program allows the user to enter a string (or character array). Next, we used While Loop to iterate each and every character inside a string. Inside this, we used printf statement to print characters, and its ASCII values. Please refer ASCII table to understand ASCII values.

/* C Program to find ASCII Value of Total Characters in a String */
#include <stdio.h>
int main()
{
    char str[100];
    
    printf("\n Please Enter any String  :  ");
    scanf("%s", str);
        
    for( int i = 0; str[i] != ‘\0’; i++)
    {
        printf(" The ASCII Value of Character %c  = %d \n", str[i], str[i]);
    }
    return 0;
}

OUTPUT

ANALYSIS
str[] = python

For Loop First Iteration: for( int i = 0; str[i] != ‘\0’; i++)
The condition is True because str[0] = p. So, compiler will execute the printf statement.

Do the same for the remaining iterations.

C Program to find ASCII Value of Total Characters in a String Example 2

This program is same as above. However, we just replaced the For Loop with While Loop.

/* C Program to find ASCII Values of Total Characters in a String */
#include <stdio.h>
int main()
{
    char str[100];
    int i = 0;
    
    printf("\n Please Enter any String  :  ");
    scanf("%s", str);
        
    while( str[i] != '\0')
    {
        printf(" The ASCII Value of Character %c  = %d \n", str[i], str[i]);
        i++;
    }
    return 0;
}
