I have ported some code from Mingw which i wrote using code::blocks, to visual studio and their compiler, it has picked up many errors that my array sizes must be constant! Why does VS need a constant size and mingw does not?
const int len = (strlen(szPath)-20); char szModiPath[len];
the len variable is underlined in red to say that its an error and says "expected constant expression"
The only way i can think to get around this is....
char* szModiPath = new char[len]; delete szModiPath;
Will i have to change everything to dynamic or is there another way in VS?

Because Variable Length Arrays are not a part of C++ although MinGW(g++) supports them as extension. Array size has to be a constant expression in C++.
In C++ it is always recommended to use
std::vector instead of
C-style arrays. :)
