Thread: The compiler stopped working

Hello guys. Do any of you know why my compiler stopped working when user try to input "Enter your choice based on the number" for the 2nd time. The 1st time it worked correctly. I got the correct output but for the 2nd time the compiler stopped. Is there anything wrong with my coding? By the way, I'm using Code Blocks as my compiler. Thanks in advance.

The output I must get:

Would you like to order a pizza [y/n]:

[2] - Island Delight
[3] - Hawaiian Delight

It's not the compiler that has stopped working, it is your program. The compiler interprets your code and generates the corresponding instructions that allow your computer to execute the code. When the compilation has finished, the compiler is done and is no longer involved.

Something went terribly wrong when you pasted in your program, and it is completely unreadable. See if you can fix it, then it'll be much easier to offer some help.
If the program fails sporadically and in a random fashion, it usually means that you have undefined behaviour or an overflow somewhere in your program. Bugs such as these might go unnoticed if the stars align, and then suddenly crash your program on the subsequent execution.

You should only delete an object after you're done with it. You're deleting Pizzahut within a loop, what happens is that during the first iteration the object is present and everything works, then you delete it and start the next iteration, wherein you're trying to access an object that has been deleted. Move the delete out of the loop, and it should work. That being said there is no reason to allocate the Pizza object on the heap in this program.

If you delete an object and later expect to use that object (in later iterations of that loop, in your case), you need to recreate that object (or a similar object). It won't magically recreate itself, and attempting to use an object after destroying it would explain your problem.

As Neo1 said, the problem is not with the compiler. It is with your program. The compiler simply does what it is told to do by the source code you give it. If the source code is faulty, you are responsible, not the compiler.
