>> string ans1 = "";
It's always a good idea to initialize your variables, but in this case doing string ans1; does initialize the string to be empty (since string is actually a class). So even if you are appending to the string that will be fine. Also, don't forget to #include <string> or the code won't compile on some compilers.
>> int ready = "";
That looks like it should be string ready; since you are asking for a Yes/No answer.
>> it just says " press any key to continue " and no errors show up..
You should probably get compile errors. If you don't and it compiles, you should definitely get to the part where it says "Enter your full name: ". Does that happen?
