Overloading prefix operator [duplicate]-CodePudding

I am trying to make a custom type in C

I am trying to overload the operator

class MyClass {
  ....
  int operator (int i) {
    ....
  }
}

That works with

int main() {
  MyClass MC;
  count << MC 1;
}

How can I get it to work with 1 MC

CodePudding user response：

This is what I did.

^ cat Foo.cpp
#include <iostream>

class MyClass {
public:
    int value = 5;
};

int operator (const int value1, const MyClass &value2) { return value1   value2.value; }

int main() {
    MyClass myClass;
    int newValue = 1   myClass;

    std::cout << newValue << std::endl;
}

^ make Foo
g       Foo.cpp   -o Foo
^ Foo
6

You'll see that I made a free function for it.
