Ok, I''m pretty new to programming so I try to be mostly a c++ person... but I realized something. Is it possible to convert a malloc statement like this, to a new statement? char *buffer; buffer = malloc(width * height * 2); How would you pull that off? ...go on and live with no regrets, you only have one life...

char *buffer;
buffer = new char[width * height * 2];

and on the other end...

delete []buffer;

Try...

char *buffer = new char[ width * height * 2 ];

with malloc you have to account for the size of the type (i think sizeof(char)==1 so it doesn''t matter in this example). but, for something else:

int v*;
// c way
v* = malloc(width * height * sizeof(int));
// c++ way
v* = new (width * height);

with new, you just worry about the dimensions.
