Answer 1

#include <iostream>

using namespace std;

class Counter{
   public:
      int counterVar;
      Counter(int c){
         counterVar = c;
      }
      void increment(){
         counterVar++;
      }
      void decrement(){
         counterVar--;
      }
      int getValue(){
         return counterVar;
      }
};

int main(){
   Counter c(5);
   cout<<c.getValue()<<endl;
   c.increment();
   c.increment();
   cout<<c.getValue()<<endl;
   c.decrement();
   cout<<c.getValue()<<endl;
   return 0;
}
