What I have tried:

The portion given below of all the questions is not showing any output !
C++
if(ch5=='d')
	    { x = x + 10;
	      cout<<"\n\n\t\t Great Job !\n\n\t\t Your score is : "<<x<<"\n\n";
	    }
	    else
	    { if((ch5=='a')||(ch5=='b')||(ch5=='c'))
	      cout<<"\n\n\t\t Sorry wrong answer !\n\n\t\t The correct answer is d) Photoelectric cells.\n\n";
	      else
	      { cout<<"\n\n\t\t Invalid option !!!\n\n\t\t Please enter a valid opition (a,b,c,d).\n\n\t\t ";
		goto AA;
	      }
	    }

Give us more code plz? I'm being sarcastic, just post the code that is relevant to the problem, we are not a debugging service. And drop the please help it's urgent.
Kenneth Haugland 8-Jan-18 1:40am    
Now that it is formatted correctly I see that you are using goto statements. Please stop using those. The code is harder to read/maintain and debugging, as you have found out, is a nightmare.

2 solutions

1) It's not urgent. It's urgent to you, because you have procrastinated and left it too late to hand in.
2) It's badly indented, so it's very hard to read and work out what is going on.
3) It's full of goto statements which make it even harder to work out what is going on.
4) We can't fix it for you because we have no idea what it is supposed to do, or what inputs you are providing to make it cause the problem. Remember, we have no access to your homework question, much less your HDD or screen...
5) Getting your code working is part of your task!

So, its going to be up to you.
Fortunately, you have a tool available to you which will help you find out what is going on: the debugger. How you use it depends on your compiler system, but a quick Google for the name of your IDE and "debugger" should give you the info you need.

Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.

Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!

Amen! And I mean that literally here :D
Griff is right the goto are making the code unreadable. Make some output for your problematic ch5 to see what is going on.

Try to eliminate ALL goto statements and use subfuctions for cleaner code.

I would write only:
C++
cin >> ch5;
