Answer 1

#include <iostream>
using namespace std;

void exchangeNumbers(int *num1, int *num2)
{
    int tmp = *num1;
    *num1 = *num2;
    *num2 = *num1;
}

int main()
{
    int RamNumber = 4;
    int AnandthNumber = 6;

    cout << "Ram magic number is " << RamNumber << endl;
    cout << "Anandth magic number is " << AnandthNumber << endl;

    cout << endl << "Kids are excanging their numbers..." << endl << endl;
    exchangeNumbers(&RamNumber, &AnandthNumber);

    cout << "Now Ram magic number is " << RamNumber << endl;
    cout << "Now Anandth magic number is " << AnandthNumber << endl;
}
