Assignment to global var. = Redefinition?

[sawer]

Hi
Why isn't assignment to global variables allowed?

int t;
t = 9;  // error C2086: 'int t' : redefinition

int main()
{
	
	return 0;
}

Thanks

Because executable statements have to be inside functions. Either:

int t = 9; // declaration and definition

int main()
{
}

or

int t;   // declaration - initialised to 0 by default

int main()
{
	t = 9;   // assignment (executable statement, must be in a function)
}

1, missing type specifier - int assumed. Note: C++ does not support default-int
2, 'int t' : redefinition

Becasue the "int assumed",so the compile think that is redefinition!

Huh?

Huh?

You used to be able to leave out the type name in C and the compiler would assume you mean int:

f(n)
{
 return n;
}
