Avoid warning 'Unreferenced Formal Parameter'
- by bdhar
I have a super class like this:
class Parent
{
public:
virtual void Function(int param);
};
void Parent::Function(int param)
{
std::cout << param << std::endl;
}
..and a sub-class like this:
class Child : public Parent
{
public:
void Function(int param);
};
void Child::Function(int param)
{
;//Do nothing
}
When I compile the sub-class .cpp file, I get this error
warning C4100: 'param' : unreferenced formal parameter
As a practise, we used to treat warnings as errors. How to avoid the above warning?
Thanks.
