Plinko help

[B260z]

Hello,

I am new to coding and could use some help to understanding what I am doing wrong. I have been trying to fix the errors, but seem unable to do so on my own. Any help or advice would be much appreciated.

First of look at line 122 which says

int main()
{

....
}

You already have a main function in the program that contains a menu. That would be your problem number 1.

Problem 2 is that you mix int's and doubles. For instance you declare const doubles as globals at the top of your program. Then, in another function, you declare an int variable and mix int with double - which gives warnings about possible data loss, so you better use one or the other.

Then at least you should see your basic menu, not much beyond that seems to be working in the current state your program is in. Where, for instance, do you call any functions that do something from main? Other than displaying the menu, of course. ;)

Run the rest of the program through the debugger a number of times and see what else does not work, or should be changed/rearranged, so that your programs functions as it should.
