Give the function prototype of the operator function which we need to define in this program so that the program has no errors.
#include <iostream>
#include <string>
using namespace std;
class Box{
    int capacity;
public:
    Box(){}
    Box(double capacity){
        this->capacity = capacity;
    }
};
 
int main(int argc, char const *argv[])
{
    Box b1(10);
    Box b2 = Box(14);
    if(b1 == b2){
        cout<<"Equal";
    }
    else{
        cout<<"Not Equal";
    }
    return 0;
}
  • a)
    bool operator==();
  • b)
    bool operator==(Box b){}
  • c)
    bool operator==(Box b);
  • d)
    Box operator==();
Correct answer is option 'C'. Can you explain this answer?
