double "enter"?

[Crunk1]

I'm pretty new to C++. I keep getting this issue when I try to use switch.

        cout<<"Enter 1 to enter student info, 2 to view student info, 3 to add course.";
        cin>>choice;

        switch(choice)
        {
            case 1://enter student info
                cout<<"\nEnter First Name: ";
                cin.getline(s.firstName, 64);
                cout<<"\nEnter Middle Name: ";
                cin.getline(s.midName, 64);
                cout<<"\nEnter Last Name: ";
                cin.getline(s.lastName, 64);
                break;

Whenever I test it and press 1 (choice is int by the way) then enter, the output is

Enter 1 to enter student info, 2 to view student info, 3 to add course.1

Enter First Name: 
Enter Middle Name: 

So, it is as if when I press enter after I press 1 that it also acts as if I pushed enter when I'm prompted to enter the first name. Why does it seem to register that I press enter twice?
I'm using Code::Blocks 10.05. Thanks!

When you did cin>>choice it only read the number and not the newline character '\n' you typed in when you pressed return.

You can absorb that with an ignore():

cin>>choice;
cin.ignore(); // skip newline char
