Do you understand what a pointer is and that you can't use an uninitialised pointer?

[Nishant]

Yes...i do know i cant use an unitialised pointer..but can you please tell me where i am doing that..i am using vectors for the first time
thanks

[Nishant]

Thanks

Have you run the program in a debugger to find exactly where it crashes or breaks?
Did you take any notice of the warning your compiler probably produced during compilations? GCC produces:

frame.cpp: In member function ‘void frame::t1changed()’:
frame.cpp:38: warning: ‘i’ may be used uninitialized in this function

frame.cpp: In member function ‘void frame::t1changed()’:
frame.cpp:38: warning: ‘i’ may be used uninitialized in this function

To copy to clipboard, switch view to plain text mode 

Why might i be uninitialised here?
What do you think that declaring a local variable int i inside a for() loop using i as its index will do?
