End of Code Loop Question

I only took 1 C++ class and am trying to remember how to write code to reloop my code. I wrote a program that asks the user to answer 5 questions, and it tells them which weather model to use based on the answers they submit. But I don't remember how to make code so that I can ask at the end if they want to test another time. Basically I have an output statement asking "Would you like to test another model (Y=Yes, N=No)" but I don't know the code to actually go through the code again. Thanks for the help

implement the whole code into a while loop

Code:

---

bool condition=true;

while(condition){
    .....main program goes here

    .....question to continue here

  if(answer == 'Y'){
      condition = true;
  }else {condition =  false;}
}
