怎么样才能这段补充程序

三 补全以下程序
#include "cs50.h"
#include
float average(int length, int array[]);
int main(void)
{
// Get number of scores
int n = get_int("Scores: ");
// Get scores int scores[n];
for (int i = 0; i < n; i++)
{
scores[i] = get_int("Score %i: ", i + 1);
}
// Print average
printf("Average: %.1f\n", average(n, scores));
}
float average(int length, int array[])
{
？
}
输出：Scores: 3
Score 1: 72
Score 2: 73
Score 3: 33
Average: 59.3

float average(int length, int array[])
{
    float avg = 0;
    for (int i = 0; i < length; i++) {
        avg += array[i];
    }
    return avg / length;
}
