    Console window closes

    Can any one help me with the code below. I am just learning C and any
    help would be appreciated. When I run the program the console opens,
    the printf in the function getData prints, I enter the data and when I
    hit return the console closes.
    Thanks

      I think you dont want the console to close. You could do that by
      putting a getch(); just before the return 0 statement in the main().

      Plz post C questions in C forums.

              This group discusses C++, not C, and so is unlikely to be of any
              help to you in C. However...
              When I run the program the console opens, the printf in the
              function getData prints, I enter the data and when I hit
              return the console closes.
              That's something outside your program which is doing it. Your
              program never opens a console (and never closes one either). So
              you really should ask in a group specific to your environment.
              // Unit 4 Project 44.cpp : Defines the entry point for the console
              application.
              If your file name ends in .cpp, you're almost certainly working
              in C++, and not C. Your first step is to decide which one you
              want, and use it. Your code looks like C; if that's what you
              want, rename your file to end in .c (and post your questions in
              comp.lang.c).

              Also, your comment above is false for both C and C++. The entry
              point for all applications (console or otherwise) in both C and
              C++ is a function called main, and I don't see any function
              called main in your code.

                  That tells me you are using Microsoft Visual C++ to run the program.

                  Hit ctrl-F5 instead of just F5 to run it.
