Pausing program with getchar();

Expand Post »
My compiler won't pause on getchar();. I have Dev C++ 4.9.9.2 and if I put getchar(); at the end of the program, it doesn't stop, and the console window still exits. It still exits when I assign a variable to it
c = getchar();
Is there another way to pause the program with C, without using system("PAUSE");

Re: Pausing program with getchar();

The program will not stop if there are still keystroks in the keyboard buffer, such as if you previously called scanf() to get an integer the '\n' will still be in the keyboard buffer. But you will have to post your program for anyone to give you more help with this.

Sure. Don't run your program in an IDE that isn't smart enough to keep the window open. Run it from the command prompt.

Re: Pausing program with getchar();

The problem arises when you are using different variables to read stuff, like ints and strings.

My advice would be to read everything in as a string and just convert to ints or floats where necessary.

Re: Pausing program with getchar();

The problem arises when you don't know how C uses stream based input. You can mix input methods without any trouble if you know what happens, but most people just make function calls without knowing what's going on. The ideal fix is to learn how stream I/O works and learn what each input function does.

No, your way promotes ignorance. Mine promotes learning.

>safer (for newbies )
Trading one mystery for another isn't safer.

>and works
Which is why I didn't immediately correct you.

Re: Pausing program with getchar();

Pelles C. Its a good IDE, similar to Dev C++. I don't know how to convert from type to another anyways...
