> read from an application program like Microsoft excel
Do you mean this?

Or do you mean read from "excel format" .xls files, and print that?

I'd like to thank you for the attempt but the thing is that the c program must read the computations from this application program i.e. the excel program and this c program should print the output on screen
thanks alot

If you're thinking of rummaging around in the address space of another process to see what it is up to - good luck!

I have done some bit of the introduction but my main worry is joining the application and c program. that is what i've failed to do

personally, this sounds like a ridiculously hard task for little to no benefit.

i'm not sure why you're even wanting to do what you describe.

i'm not even sure if it can be done.
