Question

Write the c++ code that will run with visual studio

With the square function below as an example, write a max function that has two int parameters and will return back the larger of the two.
Also write a main which can be used to test your function.

ex ) int square(intnum); // funcprototype
int main()
{
   inta = 5, b;
a = square(a);
   b = square(4);cout<< square( 6 ) << endl;
   ....
      
// func definition
//belown main

int square( intnum) {
       num= num* num;
       return num;
   }

Answer 1

#include <iostream>

using namespace std;

int square(int num); // funcprototype
int max(int n1, int n2);

int main() {
    int a = 5, b;
    a = square(a);
    b = square(4);
    cout << square(6) << endl;

    cout << "max of " << a << " and " << b << " is " << max(a, b) << endl;
    return 0;
}

// func definition
//belown main

int square(int num) {
    num = num * num;
    return num;
}

int max(int n1, int n2) {
    if (n1 > n2)
        return n1;
    else
        return n2;
}
