void do_something(int v);
why i don't need to specify the vector size in the function parameter?
how does the compiler knows the size of it? (i think that it takes from the function call... right?)
void do_something2(int v);
ok ok, i don't have to specify the lines size, but i have to specify the columns size... if the compiler can "take automatically" the lines size (as in the first example), why it don't take the columns too?
(sorry for the bad english, it's not my native language)
