Please use code tags when posting code. That's really hard to read.

sorry, i fixed it

What kind of debugging have you done on it so far?

The seg fault appears to happen when you declare the new Individual object on line 544.

none yet (i know its a bad answer), i have no idea how to fix it neither

So you wrote all this code and didnt bother to compiler and run it till the end?
Tip: Working one function at a time, saving it, compiling, and debugging it, doing a small test of it if you can save you alot of trouble when you arrive to a sitution if you dont know where error might be occuring in this mess just follow donald's suggestion he has seemed to ran through it for you

Indeed, I have.


OP: What compiler are you using? Regardless, most have some sort of debugging functionality that allows you to step through the code. If you do this, you will see that it runs to line 237, where it calls

newUserInterface.MainMenu();

and jumps to line 544:

Individual newIndividual;

Execution never makes it to line 545 due to the seg fault:

menuBool=true;

Take a look at how instances of Individual are created.

From what my debugger is telling me, you have a stack overflow on line 544

I broke it down to a simpler code (just the constructor of the Individual) and the mainMenu, and i'm still getting the segmentation fault. I haven't even defined any functions and its already giving me this error. Whats going on?

found the error, thank you all for the input, i'll definately be compiling while coding more often

Glad you found the error and learned a lesson also. What ended up being the cause of the fault?
