Question

#include <stdio.h>

extern unsigned long long sum(unsigned int *array, size_t n);

int

main(void)

{

unsigned int array[] = { 1, 1, 1, 3 };

unsigned long long r = sum(array, sizeof(array) / sizeof(*array));

printf("Result is: %llu (%s)\n", r, r == 6 ? "correct" : "incorrect");

return 0;

}

Complete the code for the line that calls the sum function. Write the sum function.

#include <stdio.h>

extern unsigned long long sum(unsigned int *array, size_t n);

int main(void) {
    unsigned int array[] = {1, 1, 1, 3};
    unsigned long long r = sum(array, sizeof(array) / sizeof(*array));
    printf("Result is: %llu (%s)\n", r, r == 6 ? "correct" : "incorrect");
    return 0;
}

unsigned long long sum(unsigned int *array, size_t n) {
    unsigned long long total = 0;
    size_t i;
    for (i = 0; i < n; ++i) {
        total += array[i];
    }
    return total;
}
