Question

using correct c++ syntax, in one part write a short header file with only one constructor and one private variable. in another part write the function definition for the same constructor of the header file you just wrote.

using a correct c++ syntax, write only the top line of a derived header file that uses a base class. write the function definitions of two constructors in this derived class

Answer 1

Header File with only one private variable and constuctor :

Num.h

class Num
{
    //private variable
    private:
        int num;
        
    //constructor
    public:
        Num(int num);
        
}; 

another part has constructor definition of header file.

Num.cpp

#include <iostream>
#include "Num.h"
using namespace std;
       
//implementation of constuctor        
Num::Num(int n): num(n) 
{
    cout << "number : " << n << endl;
}

In another file, import a header file and call that constructors.

Main.cpp

#include "Num.h" 

int main()
{
    Num n1(35); 
    Num n2(15); 
    return 0;
}

OUTPUT :
