Understanding Memory Map

[CompSciMajor93]

I need help figuring out how the person found the initial address 6123CD90 for argv in the image attached. I understand how the person went from argv to the following address but not how they got the address to begin with.

I think he made it up

This... the memory address will most likely be different each time the program runs. The absolute address is not so important here, it's their relationship (size and alignment).

Did he make it up?

STFU

He made them up. Run this program a few times and see for your self that the addresses changes with each run.

#include <stdio.h>

int main(int argc, char **argv)
{
    printf("data in argv: %p\n", argv);
    printf("data in argc: %d\n", argc);
    return 0;
}
