C how do I check if an array is full?

Question

I have an array: array[3][3]

I will let the user input data into the array as long as it is not full. As soon as the array gets full I want to stop the user from inserting more data into it.

Answer 1

You cannot check if "array is full". To do what u want to do, keep track of index while adding elements to array.

Answer 2

C has no array bounds check. You have to do it yourself. Use a variable to keep track of how many items you have inserted, and stop when your counter is equal to the array size.
