I am new to programming and bought Jumping into C++ by Alex Allain. I am working through the practice problems and was hoping someone could take a look at this and let me know if I am writing the code in an appropriate format.

My program compiles and runs fine. I just do not want to get into any bad habits. Any reviews would be greatly appreciated.

Thanks,

Code:
#include <iostream>

using namespace std;

// Chapter 4 practice problem 1
// Ask the user for two users' ages and indicate who is older
// Behave differently if both are over 100

int main()
{
    int age1;
    int age2;

    cout << "This program will compare two ages and let you know which is older\n";
    cout << "Enter age 1: ";
    cin >> age1;

    cout << "Enter age 2: ";
    cin >> age2;

    if ( age1 < age2 )
    {
        cout << "Age 1 is younger than Age 2\n";
    }
    else if ( age1 == age2 )
    {
        cout << "They are both the same age!\n";
    }
    else
    {
        cout << "Age 2 is younger than Age 1\n";
    }

    if ( age1 > 100 && age2 > 100 )
    {
        cout << "They are both very old!\n";
    }
}
