it appears that the program is stopping mid cout and i have no idea why this happens. help me please.
Disch (13742)
it's possible more text has been sent to cout, but cout did not display it onscreen yet because it wasn't flushed. Do not rely on cout statements alone to tell you where a program is hanging.

This is a perfect opportunity to learn how to use the debugger.

Set a breakpoint on the call to step3 and step through the code and find out what the program is doing.

I suspect it's hanging inside of your step4 function because that loop is very iffy. If 'mid' is false, or if your board isn't arranged just so, that loop will deadlock your program.

i have tried the breaks with the debugger. the problem is it stops in the middle of a cout function, not in the middle of a loop. that is the issue and im not sure why that happens. so it does not even get to the step 4 function. PS this is a friends code so im not the familiar with the logic of it.

You have an endless loop in step 4, not quite sure why you have a loop there in any case. Get rid of it and the program should run.
