reading a content of a text file

How to write a program to read a content of a text file.
Actually i need to create a front end for a C program.
By clicking a button, it should call the .exe of the c program and displays the output of the program which is present in .txt file.

Can anyone guide me to write this program

See CreateProcess() Windows API for creating a new process (running your executable). Then, for displaying the text file, well, that depends on the way you want to display it. For instance you can run notepad.exe providing the path as an argument. Or you can display it in your own application. So you have to explain more.

Thanks for ur reply.I hav some more doubts.
Is it possible to use system command in VC++.
I have to execute/open a command prompt to execute a c file from a button click.
Is it possible to do this using createprocess

You can't execute a c file. You need to compile it first.

With ShellExecuteEx combined with WaitForSingleObject you can execute a exe file and wait for it to end.

I hav been asked to execute a C program from VC++ program using buttonclick event.
Is it possible to do this?

Yes, but it has to be compiled first. The you can run the executable with CreateProcess(). What's not clear?
