Question

In a C++ tutorial this person uses this code:
(int)(X + NewX)
Can anyone explain to me why the (int) is infront? He doesn't explain that part in his tutorial, but I need to know.
Thanks in advance

Answer 1

what are the data types for X and NewX?
(int) someVariable;
basically casts someVariable to an int.

e.g. lets say we had:

long y = 3L;
int x;

then you can assign the value of y to x as follows:

x = (int) y;

you have to be careful with though as you run into problems if the value in y is larger than the maximum int value.

Answer 2

I always thought there was another way to do it, never knew there was such easy way like this.

Thanks for the explanation :)
