How can i see my C program disk space usage ?

Question

My question is how can i see how much memory does my C program take on my hard disk. I want to know a little bit better in depth about memory. For example:

#include<stdio.h>

int main()
{
int n=5;
return 0;
}

Where can i find how much disk space does this program take ? And if i add another line int n1=5; it should take, if we mark the memory of the first program as X, X+4bytes. Is this right or have i done something wrong ? I was looking at the main.c file properties size on disk was increasing only by writting and in the main.exe the size on the disk wasn't even changing.

Answer 2

I like the idea but it wasn't what i was looking for. Nevertheless i found out that this question can't be answered because it's a really big field of knowledge.
