Const Member Functions The code given below does not compile due to const issues.

Question

Modify the existing class code and add const in the appropriate locations to make it compile with the existing main and printNumber

#include <iostream>

using namespace std;

//Do not modify anything on or above the line below this6

//YOUR_CODE_BELOW

class EvenNumber {

private:

   int value;

public:

   EvenNumber(int startValue) {

       //use our function to do the work...

       setValue(startValue);

  }

​

   int getValue() {

       return value;

  }

   void setValue(int newValue) {

       //if given odd number, increase by 1

       if(newValue % 2 == 0)

           value = newValue;

       else

           value = newValue + 1;

  }

​

   void increment() { value += 2; }

​

   void decrement() { value -= 2;

​

};

//YOUR_CODE_ABOVE

//Do not modify anything on or below the line above this

void printNumber(const EvenNumber& n) {

   cout << n.getValue() << endl;

}

​

int main

{

   EvenNumber e1(4);

   e1.increment();

   printNumber(e1);

​

   return 0;

}
