What will be the output of the following C++ code?
#include <iostream>
#include <string>
using namespace std;
class Box{
    int capacity;
    bool operator<(Box b){
        return this->capacity < b.capacity ? true : false;
    }
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)
    Error
  • b)
    Segmentation fault
  • c)
    Box 2 has large capacity
  • d)
    No output

As the operator overloaded function defined is private therfore on comparison the function cannot be called from outside therefore the program gives error.

What will be the output of the following C++ code?#include <iostrea...
Explanation:

Error:
- The code will result in an error because the operator< function is defined incorrectly in the Box class.
- The correct way to define the less than operator in C++ is to make it a friend function or a member function that takes a constant reference to the object being compared.

Code Issue:
- The operator< function in the Box class is missing the const keyword before the parameter Box b.
- It should be defined as bool operator<(const box&="" b)="" const="">

Corrected Code:
cpp
#include
#include
using namespace std;
class Box {
int capacity;
public:
Box() {}
Box(double capacity) {
this->capacity = capacity;
}
bool operator<(const box&="" b)="" const="">
return this->capacity < />
}
};
int main(int argc, char const *argv[]) {
Box b1(10);
Box b2 = Box(14);
if (b1 < b2)="" />
cout < "box="" 2="" has="" a="" larger="" />
} else {
cout < "box="" 1="" has="" a="" larger="" />
}
return 0;
}

Explanation:
- The corrected code defines the less than operator correctly as a member function that takes a constant reference to the Box object being compared.
- The comparison in the main function will now work as expected without any errors.
