is it good or bad to reuse the variables?

Question

I wonder if it is good or bad (or does not matter) if I reuse the variable names as much as possible? for example

int main(void){
  //...
  int x=0;

  //..

Put it this way - how would you like it if I wrote a big pile of undocumented, complex code in such a way and, then, you get the job of maintaining/enhancing it.

Please do not do such a thing, ever :)
