Answer 1

#include <iostream>
using namespace std;
class Box{
    float length, width, height, size;
    public:
    Box(){}
    Box(float l, float w, float h){
        this->length = l;
        this->width = w;
        this->height = h;
        this->size = l * w * h;
    }
    void operator==(const Box a){
        cout<<"The size of the smaller box is ";
        if(this->size > a.size) cout<<a.size;
        else cout<<this->size;
    }
};
int main(){
    Box* boxes;
    float l, w, h;
    for(int i = 0; i < 2; i++){
        cout<<"Input dimensions of box "<<i + 1<<endl;
        cin>>l;
        cin>>w;
        cin>>h;
        boxes[i] = Box(l, w, h);
    }
    boxes[0] == boxes[1];
    return 0;
}
