Uhh help real quick please...

I might be going crazy but in C++ can't you assign a value to a variable in the global scope?

Code: Select all

int a;
a = 20;

int main()
{
return 0;
}

Either my compiler is being retarded and not letting me do this or I'm losing my mind... or I'm tired.

[qpHalcy0n]

int a = 20; // This is value assignment and is valid.


int a;
a = 20; // This is an executable piece of code and is NOT valid in the global scope.

[Bludklok]

int a = 20; // This is value assignment and is valid.


int a;
a = 20; // This is an executable piece of code and is NOT valid in the global scope.

Thought so...

Such a basic rule too. Just been under a lot of stress lately.

int a = 20; // This is value assignment and is valid.

Wow, I never realised you could do that in the global scope

[sparda]

int a = 20; // This is value assignment and is valid.

assignment != initialization.

That is why you can initialize:

Code: Select all

int a = 20; // Initialization

And not be able to assign in global scope:

Code: Select all

int a;
a = 20; // assignment
