need some help with last part of arrays
The last part of this project is that I have to read the numbers from a text file. I've looked at all the posts and FAQ's but they haven't really help me since, I'm not allowed to use sizeof, malloc or anything like that for this project.
I have to use fscanf to put the list of numbers from the text file. and the size of the array back to main. Part of it is I dont' know what to make with my for loop, the other part i don't know. As I said on my other post the array size is not set, instructor will test it with a random list he has of 1-100 numbers though. When I get the array back to main and the size everything I'll be done. Thank you.
