How to use source file in function !!!!!

Question

what is the deal with source file and function I couldn't understand it at all and to return an array from a function using the source file!

Answer 1

It would help to know where you got this idea because, as you question is written, it makes no sense to me (and likely others as no one has replied.)

Answer 2

Based on what you have posted, I'm guessing create a source file in C to read a matrix. Put the read of it's values in a separate function. The values of the matrix could come from two places: user input to prompts or a file so I'm guessing file.

Answer 3

actually it was a lecture today about c programming files I was asked to create a program with a file to read a matrix but the teacher didn't explain that much about the source file so I didn't quite understand how to do that
