A problem using DJGPP

矮牧也疯狂

I do n’t know if you have used GNU C ++ 's Windows version of DJGPP. I used the included IDE program RHIDE to run the program in a single step. There was a problem. When the program ran to a user such as "cin >> a", the problem Appears, after you enter the data and press Enter, the screen does not return to the IDE, but runs until the program ends and then returns.
Help experts, how to solve it?
Greatful!
