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

C Basic Declarations and Expressions: Exercise-133 with Solution

Sum two integers and count digits in the result

Write a C program to calculate the sum of two given integers and count the number of digits in 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; // Initialize a counter to keep track of digits
    sum_val = x + y; // Calculate the sum of x and y

    // Loop to count the number of digits in the sum value
    while (sum_val != 0)
    {
        if (sum_val > 0)
        {
            sum_val = sum_val / 10; // Divide by 10 to remove the rightmost digit
        }
        ctr++; // Increment the counter
    }

    // Print the number of digits in the sum value
    printf("\nNumber of digits of the sum value of the said numbers:\n");
    printf("%d\n", ctr);

    return 0; // End of program
}

Sample Output:

Input two integer values:
68
75

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