resize a 4d vector

Question

How can I resize a 4d vector in C++?

Answer 1

if you are using an stl vector, then a simple push_back() will add an extra element. If you are using C styled arrays then you may have to copy the smaller array into a new bigger array.

Answer 2

Depends entirely on which dimension you're attempting to resize, but

void resize( size_type num, TYPE val = TYPE() );

would likely be a good place to start. If you want more specific help, you may need to make your question more specific. Code snippets are especially useful also, if you seek an accurate answer to your situation.
