find sum of first and last digit of any number

find sum of first and last digit of any number

Write a C program to input a number and find sum of first and last digit of the number using for loop. How to find sum of first and last digit of a number in C programming using loop. Logic to find sum of first and last digit of a number without using loop in C program.

    Input a number from user. Store it in some variable say j.
    To find last digit of given number we modulo divide the given number by 10. Which is lastDigit = j % 10.
    To find first digit we divide the given number by 10 till j is greater than 0.
    Finally calculate sum of first and last digit i.e. sum = firstDigit + lastDigit.

#include <stdio.h>

int main()
{
    int j, sum=0, firstDigit, lastDigit;

    /* Input a number from user */
    printf("Enter any number to find sum of first and last digit: ");
    scanf("%d", &j);
    
    /* Find last digit to sum */
    lastDigit = j % 10;

    /* Copy j to first digit */
    firstDigit = j;

    /* Find the first digit by dividing j by 10 until first digit is left */
    while(j >= 10)
    {
        j = j / 10;
    }
    firstDigit = j;

    /* Find sum of first and last digit*/
    sum = firstDigit + lastDigit; 

    printf("Sum of first and last digit = %d", sum);

    return 0;
}
