Are you mixing cin and getline? http://www.cplusplus.com/forum/articles/6046/
And please use [c ode][/c ode] tags.

It seems not my point. when i leave codes from line 55 to 64, program work well. In other word, It stops to waite one character from keyboard. I use DEV-C++ to compile
and it appear an announcemet:
"This application has requested the Runtime to terminate it in an unusual way."

"This application has requested the Runtime to terminate it in an unusual way."
I would check lines 45, 47, and 59. Line 61 is definitely going to fail, since you're trying to access element n of a string of size n.
