How to write a C Program to find ASCII Value of Total Characters in a String using For loop and while loop with a practical example.
C Program to find ASCII Value of Total Characters in a String Example
This program uses For Loop to iterate each character inside a string. Inside this, we used the printf statement to print characters and their ASCII values. Please refer to the ASCII table to understand ASCII values in C Programming.
/* 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, the compiler will execute the printf statement.
Do the same for the remaining For Loop iterations.
Program to find ASCII Value of Total Characters in a String using While loop
In this ASCII values C program, We 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;
}
OUTPUT
