I have a simple question. I have this code :

int foo();
int main (int argc, char** argv){
printf("- foo: %p\n",foo);
printf("- foo: %p\n",&foo);
}

I noticed both lines print a very low address (text segment), but I don't understand the difference between the lines.

There is none, a function *decays* to a pointer to itself naturally, so `foo` will be the same as `&foo`. – Some programmer dude Apr 01 '20 at 08:02
functions and arrays without parentheses have no other meaning.than possessing & – Soner from The Ottoman Empire Apr 01 '20 at 08:05
