Answer to Question #349382 in C++ for vince

Question

1. In the code editor, you are provided with a main() function that asks the user for 2 integers. Then, a function call to a function named, exchangeGift() is made and the addresses of the 2 integers are passed.
2. This exchangeGift() function hasn't been implemented yet so this is your task. This has the following description:
3. Return type - void
4. Name - exchangeGift
5. Parameters - 2 addresses of 2 integers
6. Description - swaps the value of the 2 integers and then adds 100 to the 2nd integer (or 2nd parameter)
7. DO NOT EDIT THE MAIN

Input

1. First integer

2. Second integer

Output

Enter·integer·1:·10
Enter·integer·2:·20
20·110

#include <iostream>

using namespace std;

int main(void) {

  int a, b;

  cout << "Enter integer 1: ";

  cin >> a;

  cout << "Enter integer 2: ";

  cin >> b;

  exchangeGift(&a, &b);

  cout << a << " " << b;

  return 0;

}

Answer 1

#include <iostream>

using namespace std;

void exchangeGift(int* a, int* b);

int main(void) {

    int a, b;


    cout << "Enter integer 1: ";

    cin >> a;


    cout << "Enter integer 2: ";

    cin >> b;


    exchangeGift(&a, &b);


    cout << a << " " << b;


    return 0;

}

void exchangeGift(int* a, int* b) {
    swap(*a, *b);
    *b += 100;
}
