Morteza Hajji string header is included in iostream header already.

There for the first input type "string" , its invalid operation x/y .. how string decided by a string ?

Answer 3

Beside what Jayakrishna🇮🇳 said, you should include string library, (#include <string>).

Answer 4

Ps. Sorry I copied wrong code I tried to skip it and rethink it again here’s the real code:

#include <iostream>
using namespace std;

//change the class to a template
template <class T>
class Queue
{
private:
int *arr;
int count;
public:
Queue(int size) {
arr = new int[size];
count = 0;
}
//my code
template <class T>:
void add(int elem) {
arr[count] = elem;
count++;
}
void get(int index) {
cout << arr[index]<<endl;
}
};

int main()
{
Queue<string> q(4);
q.add("James");
q.add("Andy");
q.add("Amy");
q.get(2);

Queue <int> n(2);
n.add(42);
n.add(33);
n.get(1);

return 0;
}
