i need help with a dinamic matrix

Sorry i know this is a stupid question but i don't know how to do this...


i need to create a dinamic matrix to capture some pixels of the screen...

i want something like this (i know this code doesn't work)

void capture_matrix (int x, int y)
{

int m[][] = new m[x][y] sizeof (int)

/*
the rest of my code
*/
}

how can i do that???? i really need to do that for capture a matrix of pixeles with getpixel(); it is for capture first a small matrix, then draw something over that and then restore the matrix with putpixel(m[cx][cy])

> int m[][] = new m[x][y] sizeof (int)

This is not C. THis is an attempt at C++.
You are on the C board. Go to the C++ board.

Quzah.

wost... i still don't know the diference between c and c++ sorry..

one...pick up a book on either C OR C++ and read up on 'em...

anything u can do in C u can do in C++ but no the other way around.

C uses malloc, realloc (i think) and free to handle dynamic memory.

C++ uses new and delete...

if ur using new u dont need sizeof btw.

if ur using malloc u do need sizeof.

pick a language then i can help u a bit more.
