C++ Question

Create my own operator in c++

I know it is possible to overload operators that already exist in c++ to define desired behavior, but is it possible to create your own operator?

Just for example, making an operator

#
that returns the size of containers:

template<typename T>
size_t operator#(const T& obj) { return obj.size(); }

vector<int> v(1024);
cout << #v; // prints 1024

Answer

No. You need to stick with the operators the parser already knows how to handle. Overloading can extend the meaning of expressions, but the syntax is fixed.
