Question

Please complete the following function getMax, which accepts three integer parameters (int p, int q, int r), and must return the maximum of those 3 integers received to the caller.

int getMax(int p, int q, int r) // returns the max of 3 integers

{ // begin getMax()

// Enter your code here:::::::::::::::::::::::::::::

    

} // end getMax()

void main( ) // To test function getMax( )

{ cout << "Data: 9 18 4 , Max = " << getMax(9, 18, 4) << endl;

cout << "Data: 99 18 4 , Max = " << getMax(99, 18, 4) << endl;

cout << "Data: 9 18 49 , Max = " << getMax(9, 18, 49) << endl;

}

The output of the above program should be as follows:

Data: 9 18 4   , Max = 18    

Data: 99 18 4   , Max = 99    

Data: 9   18 49 , Max = 49

Answer 1

#include<iostream>
#include<string>
using namespace std;
int getMax(int p, int q, int r) // returns the max of 3 integers
{ 
    int res = p;
    
    if(res < q){
        res = q;
    }
    if(res < r){
        res = r;
    }
    return r;
} // end getMax()

int main() // To test function getMax( )
{
    cout << "Data: 9 18 4 , Max = " << getMax(9, 18, 4) << endl;
    cout << "Data: 99 18 4 , Max = " << getMax(99, 18, 4) << endl;
    cout << "Data: 9 18 49 , Max = " << getMax(9, 18, 49) << endl;
    return 0;
