The "Big Five" Exercises

   < Previous  Next >
  1. What are the "Big Five"?
  2. In general, when it is required to use the "Big Five" (instead of the defaults)?
  3. Given the declaration of the SimpleDoubleHolder class, write:
    1. Constructor (with optional argument)
    2. The names and the function prototypes for each of the "Big Five"

    bigFiveExercises.cpp: 
    #include <iostream>
#include <string>
using std::string;
using std::cout;

class SimpleDoubleHolder{
public:
    // 1) Constructor (with optional argument)
    
    // 2) Include the "Big Five" here
    // 2a) 
    
    // 2b) 
    
    // 2c) 
       
    // 2d) 
    
    // 2e) 
        
    void setDouble( double value);
    void printDouble();
    
private:
    double* m_DoublePtr;
};

void SimpleDoubleHolder::printDouble(){
    cout << "m_DoublePtr: ";
    if( m_DoublePtr == nullptr){
        cout << "nullptr\n";
    }else{
        cout << *m_DoublePtr << "\n";
    }
}


// setter for data member
void SimpleDoubleHolder::setDouble( double value){
    m_DoublePtr = new double( value);
}


// Constructor (with optional argument)
