Why does the variable address change after every execution in C?

Question

int i=10;
printf("Address of i = %u",&i);

Output:
Address if i = 3220204848

Output on re-execution:
Address of i = 3216532594

I get a new address ievery time I run the program. What does this mean?

Answer 1

This means that every time you load your program, a different (virtual) address is loaded. This feature, called Address Layout Randomization (ASLR) , is a feature of most modern operating systems.
