[编程入门]宏定义之找最大数(数组方法)

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#define Max(a,b,c) ((a>b?a:b))>c?(a>b?a:b):c

double max(double arr[])

{

    int i = 0;

    for (i = 1; i < 3; i++)

    {

        if (arr[0] < arr[i])

        {

            arr[0] = arr[i];

        }

    }

    return arr[0];

}

int main()

{

    double arr[3] = { 0 }, a, b;

    int i = 0;

    for (i = 0; i < 3; i++)

    {

        scanf("%lf", &arr[i]);

    }

    a = max(arr);

    b = Max(arr[0], arr[1], arr[2]);

    printf("%.3lf\n%.3lf", a, b);

    return 0;

}
