c++ program to make a heater with lowest and highest temperatures using a class and objects.

#include <iostream>                                  

using namespace std;

class heater

{

private:

    int temp;

    int mini;

    int maxi;

    int incre;

public:

    heater()

    {  temp=15;}

    heater (int z )

    {  incre=z;}

    heater(int x, int y): mini(x),maxi(y)

    { }

    void warmer()

    {

        temp=temp+incre;

        if(temp>maxi)

            cout<<"warmest temperature"<<temp<<endl;

        else

            cout<<"temperature is high";

    }

    void cold()

    {

        temp=temp-incre;

        cout<<"temperature is cold"<<temp;

  }

    int output()

    {

        cout<<temp<<endl;

        return temp;

    }

};

int main()

 heater obj2(5);

    heater obj3(0,30);

    temp.warmer();

    temp.cold();

    temp.output();

retorn 0;
