Given the following C++ code. How would you define the < operator for Box class so that when boxes b1 and b2 are compared in if block the program gives correct result?
#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<<"Box 2 has large capacity.";
    }
    else{
        cout<<"Box 1 has large capacity.";
    }
    return 0;
}
  • a)
    bool operator<(Box b)
    {
        return this->capacity < b.capacity ? true : false;
    }
  • b)
    bool operator<(Box b)
    {
        return this->capacity > b.capacity ? true : false;
    }
  • c)
    bool operator<(Box b)
    {
        return  b1 > b2 ? true : false;
    }
  • d)
    bool operator<(Box b)
    {
        return this < b ? true : false;
    }
Correct answer is option 'A'. Can you explain this answer?

As we need to give the result after comparing the capacity of two boxes. We use < operator and as this is the first operand and second operand is passed so we need to do this->capacity < b.capacity (passed object) to make the program run.

Given the following C++ code. How would you define the < operator f...

Explanation:

Defining the < operator for Box class:
- To compare two Box objects in the if block, we need to define the < operator="" for="" the="" box="" />
- The < operator="" should="" compare="" the="" capacity="" of="" two="" box="" />

Correct implementation:
- The correct implementation for the < operator="" in="" the="" box="" />
cpp
bool operator<(box>
return this->capacity < b.capacity="" true="" :="" />
}

- This implementation compares the capacity of the current Box object with the capacity of the Box object passed as a parameter.
- It returns true if the capacity of the current Box object is less than the capacity of the passed Box object, otherwise it returns false.

Explanation of the implementation:
- The implementation of the < operator="" uses="" the="" ternary="" operator="" to="" compare="" the="" capacities="" of="" two="" box="" />
- It compares the capacity of the current object (this->capacity) with the capacity of the passed object (b.capacity).
- If the capacity of the current object is less than the capacity of the passed object, it returns true, indicating that the current object has a smaller capacity.
- If the capacity of the current object is not less than the capacity of the passed object, it returns false, indicating that the current object has an equal or larger capacity.

Usage in the if block:
- When the < operator="" is="" defined="" in="" the="" box="" class="" as="" shown,="" the="" comparison="" between="" b1="" and="" b2="" in="" the="" if="" block="" will="" give="" the="" correct="" result="" based="" on="" the="" capacity="" of="" the="" box="" objects.="" operator="" is="" defined="" in="" the="" box="" as="" shown,="" the="" comparison="" between="" b1="" and="" b2="" in="" the="" if="" block="" will="" give="" the="" correct="" result="" based="" on="" the="" capacity="" of="" the="" box="" />
