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?

This answer quotes ChatGPT

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;
    }
