编程用带参数的宏计算并输出三个数中最大数

#include <iostream>
using namespace std;

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

int main()
{
cout<<max(1,2,3)<<endl;
return 0;
}

#include <stdio.h>
#define MAX(a,b,c) (((a>b)?a:b)>c)?((a>b)?a:b):c
int main()
{
int x,y,z,max;
printf("Input three numbers:\n");
scanf("%d%d%d",&x,&y,&z);

max=MAX(x,y,z);
printf("The max number is %d.\n",max);
return 0;
}

#define MAX(A, B, C) max(max(a, b), c)

可以直接调用printf("the max number is %d.\n", MAX(1,2,3));
