c语言中对象式宏应用的典型程序示例

1、

#include <stdio.h>

#define NUMBER 4

int main(void)
{
    int i;
    int a[NUMBER];
    int sum = 0;
    puts("please input the scores.");
    for (i = 0; i < NUMBER; i++)
    {
        printf("a[%d] = ", i + 1); scanf("%d", &a[i]);
        sum += a[i];
    }
    
    printf("sum = %d\n", sum);
    printf("mean = %.2f", (double)sum/NUMBER);
    return 0;
 }
