Help with Functions

UPDATE
Hello, just started learning C++ and Im writing a little game.

How would I get line 148-156 to rerun after PlayerClass is done? Ive looked at for loops, but cant find anything that would let me look around the room again after I open one of the door, window, or chest.
Also any help on errors that you might find would be great, variables are displaying strange values in the program.

I have the feeling im just writing this completely wrong, any info on how Id do it would be much appreciated.

Well it returns 0 because in line 146, you have 'return 0'. What do you want that function to return? the type of that function is 'int' and I don't think you want it to return 0, do you?
You have several other problems:

Line 50: spec is an uninitialized variable. Your comparisons at lines 56,59,62,65 are going to result in undefined behavior.

Lines 51-54: stamina, agility, intellect, luck are local variables and go out of scope at line 86.

Line 96-99: These are also local variables that go out of scope at line 170.

Line 178: Actions1() is not defined.

Thank you my man, you helped me understand, not working yet but seriously helped me out. Was up waay to long my mind was mush thats where the undefined variable came from :p But seriously thanks dude
Okay I dont get whats wrong with spec, it gets initialized with cin >> spec; then after cout outputs, works the same as all my other variables

Your variable spec is only initialized by std::cin at line 35 after your if/else block, lines 23-33.

Move line 35 up so it executes before the if/else block.

Thank you, dont know how I misunderstood that. Any advice on rerunning the code to look around the room again after opening the chest?
The easiest way is a simple loop.

  bool chest_opened = false;

  do 
  {  //  look around the room (ideally, call a function).
      if (action1 == "open chest")
      {  chest_opened = true;
      }
  }
  while (! chest_opened);
