C++ Templates / Specialization

I want to have a class that is accessible with and without template parameters. See the example below. I did some research but didn't find anything helpful, except template specialization but that is not what I want.

class Execute
{
  ...
}

template<class T>
class Execute
{
  ...
}

I want to be able to create objects of these classes like:

Execute exec1;
Execute<int> exec1;

Does anyone have an idea on how to achieve this? I did several setups but none did succeed.

Not exactly what you want, but you can specify a default template argument:

template<class T = void>
class Execute
{
};

template<>
class Execute<void>
{
};

Execute<> exec1; // Instantiates Execute<void>
Execute<int> exec2;
