    Compile this and watch the result
    Code:
    int MyVariable;
    int* MyPointer;
    
    Myvariable = 5;
    MyPointer = &MyVariable; //make the pointer pooint to MyVariable
    
    cout << "MyPointer: " << MyPointer << endl; //Print the value of the pointer (the adress)
    cout << "*MyPointer: " << *MyPointer << endl;//Print the value of what the pointer points at
    cout << "MyPointer[0]: " << MyPointer[0] << endl;//Print the first element of what the pointer points at (pointers are like arrays). This is usually the same as *MyPointer
