Courtesy of writing a single sentence and then copypasting it
As I fixed it I encountered another problem, when I run the program and it asks me for metres I enter it and then it goes straight to the last else sentence where it displays the correct entered value of P but does not even give me a chance to enter U

I'm going to bow out of the conversation now.

It seems you've stopped debugging your own homework because we're doing it for you.

Nothing you've done or are doing is hard. It just requires you to pay attention and make a little more effort.

Step through your program in the debugger line by line and look at the values of the variables and *think* as to why each if passes or fails. Logic and reasoning skills will take you a long way.

I was actually watching these videos as I waited for a reply from the community, I have used do&while earlier for programs with multiple questions. Is that what I should now?
In addition , I use devcpp as it is required by the lecturers of my eCourse.

Tried using do-while method from my previous experience, the problem remains the same.

[#define]

This is a common problem for beginners.

26   cin >> P;
  
29   getline(cin, U);

cin >> P; leaves a newline in the input stream.
getline(cin, U); reads the newline as an empty string.

There are various ways of dealing with this such as using the ignore function.

Here though you can just use another cin >>, I think.

26   cin >> P;
     
29   cin >> U;
