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?
