Simple C ++: how to overload the multiplication operator to float * myClass and myClass * float

Question

class MyClass; int main() { float a = 5; MyClass c1; MyClass c2 = a*c1; MyClass c3 = c1*a; } 

How can I overload the multiplication operator so that operations a * c1 and c1 * a are performed?

Answer 1

Same:

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

The second can also be a member function:

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

The first 2 options work like ads outside the class.
