Summary: Shouldn't this be a compile time error?
Product: gcc
Version: 4.4.3
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: rahul.pa...@gmail.com
1 #include
2 long factorial(int arg=2);
3 int main() {
4 cout<<factorial();
5 }
6 long factorial(int arg_number) {
7 return arg_number;
8 }
Output:
2
Notice line 2 and 6
Different name is given to argument in declaration and definition.
Also default value is provided in declaration (to a variable name which is not
present in definition) and not in definition.
Shouldn't this trigger some kind of compile error ?
Output of gcc -v
Using built-in specs.
