Sample test cases : Input 1 : 45 Output 1 : Alex is 25 years old. Bob is 20 years old. Input 2 : 91 Output 2 : Alex is 48 years old. Bob is 43 years old.
Solution
Sure, here is a simple C++ program that uses pointers to calculate and print the ages of Alex and Bob.
#include <iostream>
using namespace std;
void calculateAges(int *sum) {
int bob = *sum / 2;
int alex = bob + 5;
cout << "Alex is " << alex << " years old." << endl;
cout << "Bob is " << bob << " years old." << endl;
}
int main() {
int sum;
cin >> sum;
calculateAges(&sum);
return 0;
}
In this program, we first take the sum of Alex and Bob's ages as input. We then call the calculateAges function, passing the address of the sum variable. Inside the function, we calculate Bob's age by dividing the sum by 2. Since Alex is 5 years older than Bob, we add 5 to Bob's age to get Alex's age. Finally, we print the ages of Alex and Bob.
