 Posted: Fri Nov 21, 2003 12:53 am Post subject: Weird syntax - question |
 |
|
Hello.
I've recently found such syntax working in GCC (2.9x & 3.x):
#include <iostream>
using namespace std;
int a = 1;
int b = 2;
void foo( int c( a + b ) )
{
cout << c << endl;
}
int main()
{
foo();
return( 0 );
}
Strangely enough - this compiles and works. foo() is considered as
parameterless: foo( 1 ) is invalid call then.
Borland 5.5 compiler does not pass this code - which _strongly_ suggest
that its rather GCC bug than standard feature.
Any ideas/comments?

Other GCC version not tried but with gcc 3.3.1 this example does not work:
"8: error variable declaration is not allowed here
:In function `void foo()':
9: error: `c' undeclared (first use in this function)"
Perhaps a bug corrected in version 3.3.1.
