# How to enter three integers x, y, and z in the main function, and use the macro MAX to solve and output the maximum value of these three numbers?

the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > here is an implementation of the function of the sample code:

``````#include
using namespace std;

#define MAX(a, b) ((a) > (b) ? (a) : (b))

int main() {
int x, y, z;
cout << "请输入三个整数：";
cin >> x >> y >> z;
int max = MAX(MAX(x, y), z);
cout << "最大值为：" << max << endl;
return 0;
}
``````

In this code, we first define a macro MAX with two arguments to find the maximum value of two numbers. In the main function, you first enter the three integers x, y, and z, and then use the macro MAX to solve for the maximum values of these three numbers and output the results. Here, for convenience, the macro MAX is used twice to solve for the maximum value of three numbers.

Here is an example of C++ code to define a macro MAX with arguments and use it in the main function to solve for the maximum value of three numbers:

``````
#include

#define MAX(a, b) ((a) > (b) ? (a) : (b))

int main() {
int x, y, z;
std::cout << "Enter three integers: ";
std::cin >> x >> y >> z;
int max = MAX(x, MAX(y, z));
std::cout << "The maximum of " << x << ", " << y << ", and " << z << " is " << max << std::endl;
return 0;
}

``````

In the above code, we first define a parameterized macro MAX using the #define keyword, which uses the tri operator to compare the sizes of two numbers and returns the larger one. Next in the main function, we enter three integers x, y, and z through std::cin, and then use the macro MAX to find the maximum values of these three numbers and output the results to the console.

AC code

``````#include
#define MAX(x,y,z) (x>y?(x>z?x:z):(y>z?y:z))
using namespace std;
float sb(float &x,float &y,float &z)
{
float max;
if(x>y&&x>z)
max=x;
else if(y>x&&y>z)
max=y;
else
max=z;
return max;
}
int main()
{
float x,y,z;
scanf("%f%f%f",&x,&y,&z);
printf("%.3f\n",sb(x,y,z));
printf("%.3f",MAX(x,y,z));
return 0;
}
``````
