Re-assigning random values

Hey. I was wondering if , when you assign a random value to x (or whatever) , (using the rand() function) you could later assign it another random value. Is this possible ?
Thanks in advance

if you mean something like this:

Code:

int x = rand();
// yada yada yada
// bla bla bla
x = rand();

then yes.

Yeah that's what I meant. Is that how to do it ?

yes.

Okay. Thanks
