simple c++: How to overload the multiplication operator so that float*myClass and myClass*float works

c++, operator-overloading

Solution

Like so:

MyClass operator* (float x, const MyClass& y)
{
    //...
}

MyClass operator* (const MyClass& y, float x)
{
    //...
}

The second one can also be a member function:

class MyClass
{
    //...
    MyClass operator* (float x);
};

The first 2 options work as declarations outside of class scope.

Problem

``` class MyClass; int main() { float a = 5; MyClass c1; MyClass c2 = a*c1; MyClass c3 = c1*a; } ``` How can I overload the multiply operator so that both a*c1 and c1*a work?
