can i use file input to set array sizes in headers?

I need to set the size of some arrays in the header file. Is it possible. The thing is that i'm programming SystemC, which is C++ with a twist, and i don't really know that much about C++ and headers.

What do you mean??

to set the size of an array within a header file???

If the arrays in the header files are staticly declared arrays, such as:

int array[10];

Then you can't set the size at run-time. However, if the arrays are just pointers then you can easily do it with dynamic memory allocation:

// Header
int *array;

// Main
cin>>size;
array = new int[size];
