Class Templates

You are making a queue management system and need to support different data types - for example, you should be able to queue names which are strings or integer numbers. So, you decide to make a Queue class template, which will store an array for the queue, and have add() and get() methods. You first create a class for integers only, to see if it works. The given code declares a Queue class with the corresponding methods for integers. Change the class to convert it into a class template, to support any type for the queue and so that the code in main runs successfully.

Remember, the syntax to make a class template is template

#include

using namespace std;

//change the class to a template

class Queue

{

private:

int *arr;

int count;

public:

Queue(int size) {

arr = new int[size];

count = 0;

}

void add(int elem) {

arr[count] = elem;

count++;

}

void get(int index) {

cout << arr[index]<

}

};

int main()

{

Queue q(4);

q.add("James");

q.add("Andy");

q.add("Amy");

q.get(2);

Queue n(2);

n.add(42);

n.add(33);

n.get(1);

return 0;

}
