define array size at later stage of program?

[DavidDobson]

Hi

I am looking for a way to declare a global array with no indication of size. Then later on in the application I need to set the array to a specific size (depending on what the code is going to be doing).

The array will need to visible/accessible for all methods in the class – has anyone got any ideas?

Thank you very much

Option#1: a pointer as global variable and malloc() to allocate the array later...

There's no such thing as a class in C.
Are you posting in the wrong forum? If so, I'd suggest using a std::vector to solve your problem.
