@@@ is this valid syntax @@@

In order to create temporary levels of scope my C++ book told me that it is valid to do this:

{
  short x = 5;
}

{
  short x = 2;
}

though, I get an error:

unqualified-id before '{' token
expected `,' or `;' before '{' token

Im using Dev-C++

Sorry... It seems this can't be done in global scope:

// wrong

{
  short x = 5;
}

{
  short x = 2;
}

int main() { ... }

// correct

int main() {
  {
    short x = 5;
  }

  {
    short x = 2;
  }
}

If you think about it, it wouldn't make sense in global scope.

You may think of using namespaces for those things

hmm, I dont even get what you're doing... maybe if i saw the whole context

what do your functions even do... just set dif values to same variable.

When you make a variable in global, global variables are always set to zero. And wherever you change them, (does'nt matter which function) it affects the same variable; when made local you can have two variables the same name but diffrent values. They have to be in different functions though.

Idk if i helped you.

lol... umm what you're doing isn't even relevant...

making 1statement block statements in main... when you make them in global it needs to be a function... why would you use them? how would you call them? they need to have types and they def need to have names...

@brokenbot. Why are you talking about functions. The OP was asking about block scope. What he was doing was attempting to define scope for a global variable, which defeats the purpose of a global variable anyway as helios pointed out.
