Hello there, I am currently only just starting to learn C++. I have come upon a point where I need something explaining, Say I assigned variables like so: #include <iostream.h> int main () { int n, x; n = 30; int y=30; x = 30; return 0; } Now basically I just wondered whether that above will of assigned 30 ? (bytes :S) to each n, y and x. Sorry for the stupid question it is just I really want to gain a full understanding before I proceed.

Basic questions, for example, concerning how variables work should probably be asked in the beginners forum.

For a start use this:

#include <iostream>
using namespace std;
instead of
#include <iostream.h>

iostream.h has been superseded by iostream.

n = 30; // Assignment of 30
int y = 30; // Initialization of y with 30
x = 30; // Assignment of 30

Try adding the line
cout << "n : " << n << endl;

That will soon tell you what value n is.

If you don''t already have it, get a book on C++. Failing that (due to financial constraints, or otherwise), there''s plenty of resources on the web.

Good luck,
Ro_Akira
