Given the definition of a class called Bag as following:class Bag{private:public:int items[100];int itemCount;Bag();bool add(int item);};Please provide the implementation of the member function: int getLast()function returns the last number that was placed into the bag.This

NOTE: Since programming language is not mentioned. Therefore answering question in C++ language. First we have to define the constructor. Then we will define the add() function to add element to array. Then we will define the getLast() function to get the last inserted element. In the end, we will display the result after creating the object and inserting element.#include <iostream>using namespace std;class Bag{ private: int items[100]; int itemCount; public: // defining constructor Bag() { itemCount=0; } bool add(int item); int getLast();};// defining add functionbool Bag :: add(int item){ if(itemCount <= 100) { items[itemCount] = item; itemCount++; return true; } else return false; }// defining getLast function to extract last element insertedint Bag :: getLast(){ return items[itemCount-1];}int main(void){ Bag ob; // inserting element in the bag ob.add(100); ob.add(65); ob.add(475); ob.add(75); ob.add(165); // displaying last inserted element cout<<"Last number inserted is:"<<ob.getLast(); return 0;}
