i've to implement prims algorithm on this graph which i've created. now i stuck on how to find cost. what i want is to visit all nodes and program should update the cost. can u help me??

Why don't you use functions to call each node? If you need data that you have aldready use, then why don't you use arrays? Make your code a little bit more readable.

Asking people to analyze 1100+ lines of code is not reasonable! As teo236 said, break it up into functions, and then identify those you are having problems with.

oh...i got it... thanks for helping me. and sorry for such a big code. actually i'm working first time in graphics liberary i hope u'll help me in future. Thanks again :)
