use C program Write a method that computes the sum of the digits in an integer. Use the following method header: int sumDigits(int n)

Sure, here's a C program that implements the `sumDigits` method as described:

#include <stdio.h>

int sumDigits(int n);

int main() {
    int n;
    printf("Enter an integer: ");
    scanf("%d", &n);
    printf("The sum of digits in %d is %d\n", n, sumDigits(n));
    return 0;
}

int sumDigits(int n) {
    int sum = 0;
    while (n != 0) {
        int digit = n % 10;
        sum += digit;
        n /= 10;
    }
    return sum;
}

The `sumDigits` method takes an integer `n` as input, and returns the sum of the digits in `n`. The main function prompts the user to input an integer, calls `sumDigits` to compute the sum of its digits, and prints the result. The `sumDigits` method uses a while loop to iterate over each digit in `n`, adding it to a running total until all digits have been processed.
