c - C程序中变量的地址

Question

#include <stdio.h>

main()
{
    int i = 5;
    printf("%d \n" , &i);
}

重复执行上述程序是否会导致变量i的地址不同？

Answer 1

是的，可以。这是来自类似问题的解释:

It signifies that your program is being loaded a different (virtual) address each time you run it. This is a feature called Address Space Layout Randomization (ASLR) and is a feature of most modern operating systems.
