Disney Princess (1st C++ Program)

I set myself the following additional goal (devised by me):

I have never programmed before and hence decided that in order to get used to c++, particularly the syntax I would make a short quiz to determine which Disney princess you are by answering two questions. I used the example from section 3.2 in the handout as a basis and modified it to perform the task I wanted as well as annotating using // to make sure I understood what was happening in each line.

//Instruction to the compiler's preprocessor to include iostream definitions.
#include  

//Specifing names in the program are defined by the c++ libraries
using namespace std;

//Specifing that main body of the program is beginning and will end with an integer (2 in this case) 
int main ()
{

    // declaring variables which are integers
     int hair, a, b, c;

    // first question cout is used to output a statement and cin to read data. 
    cout << " What best describes your hair? 1. black 2. blonde/white 3. ginger/brown " << endl ;
    cin >> hair;

    // determining the result 
   if (hair == 1) { 
     cout << " Which is your favourite animal? 1. dragon 2. bird 3. racoon 4. frog 5. tiger " << endl ;
    cin >> a;
    if (a == 1){
        cout << " Mulan " ;
    } if (a == 2) {
        cout << " Snow White " ;
    } if (a == 3) {
        cout << " Pocahontas " ;
    } if (a == 4) {
        cout << " Tiana " ;
    } if (a == 5) {
        cout << " Jasmine " ;
    }
}

if (hair == 2){ 
     cout << " Which is your favourite animal? 1. reindeer 2. lizard 3. mouse 4. owl " << endl ;
    cin >> b;
    if (b == 1) {
        cout << " Elsa " ;
    } if (b == 2) {
        cout << " Rapunzel " ;
    } if (b == 3) {
        cout << " Cinderella " ;
    } if (b == 4) {
        cout << " Aurora " ;
    }
}

if (hair == 3) { 
     cout << " Which is your favourite animal? 1. bear 2. fish 3. reindeer 4. horse" << endl ;
    cin >> c;
    if (c == 1){
        cout << " Merida " ;
    } if (c == 2) {
        cout << " Ariel " ;
    } if (c == 3) {
        cout << " Anna " ;
    } if (c == 4) {
        cout << " Belle " ;
    }
}


    // terminate the program:
    return 2;
}
