Beginner assembly programming memory usage question
- by Daniel
I've been getting into some assembly lately and its fun as it challenges everything i have learned. I was wondering if i could ask a few questions
When running an executable, does the entire executable get loaded into memory?
From a bit of fiddling i've found that constants aren't really constants? Is it just a compiler thing?
const int i = 5;
_asm { mov i, 0 } // i is now 0 and compiles fine
So are all variables assigned with a constant value embedded into the file as well?
Meaning:
int a = 1;
const int b = 2;
void something()
{
const int c = 3;
int d = 4;
}
Will i find all of these variables embedded in the file (in a hex editor or something)?
If the executable is loaded into memory then "constants" are technically using memory? I've read around on the net people saying that constants don't use memory, is this true?
