C语言函数：求数组最大值、最小值和平均值

#include <stdio.h>

int max, min;

float fun(int a[], int n) { float sum = 0; max = min = a[0]; for (int i = 0; i < n; i++) { if (a[i] > max) max = a[i]; if (a[i] < min) min = a[i]; sum += a[i]; } return sum / n; }

int main() { int x[10], i, m, n; float p; for (i = 0; i < 10; i++) scanf('%d', &x[i]); p = fun(x, 10); printf('max=%d,min=%d,average=%.2f\n', max, min, p); return 0; }
