variable scope in statement blocks
- by fearofawhackplanet
for (int i = 0; i < 10; i++)
{
Foo();
}
int i = 10; // error, 'i' already exists
----------------------------------------
for (int i = 0; i < 10; i++)
{
Foo();
}
i = 10; // error, 'i' doesn't exist
By my understanding of scope, the first example should be fine. The fact neither of them are allowed seems even more odd. Surely 'i' is either in scope or not.
Is there something non-obvious about scope I don't understand which means the compiler genuinely can't resolve this? Or is just a case of nanny-state compilerism?
