I'm writing a pretty simple program, but I faced a problem in limiting user input data. For example, if I have a 2D-array of a certain size and I asked the user to input the array column by column but the problem is when I run the program it mix the numbers together.
what I actually need is to delete the rest of numbers which are not part of this column so if the size=3 and the user input 1 2 3 4 5 I need the program to skip 4 & 5 and...

How to limit the number of integers inputted by the user ?
-
But I don't need a dynamic array, I just need to make it optional for the user to enter any size of array and then this size become static ( I mean the array become static ), so I don't need to free the memory because no extra memory is available, am I right ?? -
Yes it gives error: "incompatib le type", it is fine I will consider the above solution.
Thank you so muchLeave a comment:

error message: subscripted value is neither array nor pointer ( lines 20, 21, 23, 24, 31).
Do I have to use double pointer ( int **a ), I mean is there another way to do this ??
And why it gives these errors !!Leave a comment:

sorry for being late, but I wasn't able to open the internet.
I read the article " Arrays Revealed " but I didn't understand all the points mentioned. For the same program how can I modify the program to return a 2-D array instead of 1-D. If I want to return different grades ( quiz, midterm, final, average ) each one in a column so what shall I do.
Honestly the article I read is really helpful but I didn't get all the points...Leave a comment:
