C Exercises: Count the number of digits of the sum value of two integer values

C Basic Declarations and Expressions: Exercise-133 with Solution

Write a C program to calculate the sum of two given integers and count the number of digits of the sum value.

Sample Solution:

C Code:

#include <stdio.h>
int main()
{
    int x, y, sum_val, ctr;
    printf("Input two integer values:\n");
    scanf("%d %d", &x, &y);
        ctr=0;
        sum_val=x+y;
        while(sum_val!=0){
            if(sum_val>0){
                sum_val=sum_val/10;
            }
            ctr++;
        }
        printf("\nNumber of digits of the sum value of the said numbers:\n");
        printf("%d\n", ctr);
    
    return 0;
}

Sample Output:

Input two integer values:
68
75

Number of digits of the sum value of the said numbers:
3
