thank again for help
i have actually given the entire susceptible code which might cause problem.and believe me it that simple as i have wrote. its compile time error.
anyways i am really sorry that i dont have code now ..i will surely post it next time when i come to browse internet.any i really apologize for that.
i just included the file as .c .i know that .h is advisable.But may i know any good reason for that will create problem later on?
thanks again..
