Question

Make a class whose objects each represent a battery. The only attribute an object will have is the battery type (one letter). Also, the class has to include the following services for its objects:
-determine if two batteries are equal
-change battery type
-get battery type display battery information

the program must include:
1.All / Part
2.Overloading of operators
3.Builder
4.Copy constructor
5.Destroyer
6.Dynamic memory

C++

Answer 1

Complete code for the following question:-

#include <iostream>
using namespace std;
class battery
{char batteryType;
public:
battery(){batteryType='A';}//constructor(builder)
battery(battery &temp)//copy constructor
{
batteryType=temp.batteryType;
}
void checkEqual(battery b) //check if two batteries are equal
{
if(batteryType==b.batteryType)
cout<<"Batteries are equal!!\n";
else
cout<<"Batteries are not equal!!\n";
}
void changeBatteryType(char type)//change battery type
{
batteryType=type;
cout<<"Battery type changed to "<<batteryType<<"\n";
}
void displayBatteryType()// display battery type
{
cout<<"Battery Type= "<<batteryType<<"\n";
}
battery operator+(battery& s2) //operator(+) overloading
{ battery s3;
if(this->batteryType>s2.batteryType)
s3.batteryType= this->batteryType;
else
s3.batteryType= s2.batteryType;
return s3; }
~battery(){}; //destructor(destroyer)
  
};
int main()//driver function to check our class
{ battery *b1= new battery; //dynamic memory of battery type
battery *b2= new battery;
b2->changeBatteryType('D');
b2->checkEqual(*b1);

return 0;
}
