C语言程序实现求一批数中的最大值最小值的差和积

以下是一个 C 语言程序，可以求一批数中的最大值、最小值、差和积：

#include <stdio.h>

int main() {
  int n, num, max, min, diff=0, product=1;
  
  printf("请输入要输入的数字个数：");
  scanf("%d", &n);
  
  printf("请输入这%d个数：\n", n);
  scanf("%d", &num);
  max = min = num;
  diff = 0;
  product = num;
  
  for (int i = 1; i < n; i++) {
    scanf("%d", &num);
    if (num > max) max = num;
    if (num < min) min = num;
    diff = max - min;
    product *= num;
  }
  
  printf("最大值为：%d\n", max);
  printf("最小值为：%d\n", min);
  printf("差为：%d\n", diff);
  printf("积为：%d\n", product);
  
  return 0;
}

该程序首先要求用户输入数字的个数，然后通过 for 循环读入每个数字，并逐步计算出最大值、最小值、差和积。最后输出结果。
