}

It complise just right but when I run it, it doesnt let me answer the questions during the unit testing and it just says I got the wrong answer...any ideas??

Explanation / Answer

Hey i got your mistake.

While you reading answer you are using

cin >> input;

Which will take only a string not line eg when you type Wii Sport it will store only Wii not Sport.

So use this

getline(cin,input);
