I have a product registration in C. Products can be up to 30 characters (columns), but can be infinite in quantity (lines).
In the variable declaration, I used:
char products [] [30];
However, when compiling, it returns that the array size can not be empty. So if I put a number of lines,
char products [10] [30];
I'm statically pre-defining the quantity of products.
How to leave this number free so that the matrix auto-increments as the user enters the data?
