Question on code from tutorial
The code on page 90 of the tutorial (the pdf version) has contained in the constructor the two lines
width = new int;
height = new int;
I don't understand what this is and why it is needed. Don't think "new" was talked about yet in the tutorial. Thanks.

new simply allocates enough memory for sizeof(int);Because there is no sequence in where the memory is located, it passes back a handle to the randomly allocated memory. You can then access your data by using the dereference(*). This is effecient for almost all large classes, large arrays, and almost everything placed inside of a buffer (audio decoding, mesh loading, useful for games).
