How to compile the following source code in VC6// I have error inVC++6 but compile ok in GCC

[fAnSKyer]

int NPart = atoi(argv[1]);
int UsePart[NPart];

I have error in VC++6 but compile ok in GCC
Which compile parameter should I use?

Thanks a lot

Best,

[Ian Collins]

int NPart = atoi(argv[1]);
int UsePart[NPart];

This is gcc specific, or C.

Use std::vector.

Do people still use VC++6?

You should use e.g. std::vector, and you should not use an archaic pre-standard
compiler like VC6.

GCC supports C99 variadic arrays (such as your UsePart) as a language extension.

You should use compiler options

-std=c++98 -pedantic

to turn that off.
