5.24.3.Compare the typeid for templates
#include <iostream>
using namespace std;

template <class T> class MyClass {
  T a;
public:
  MyClass(T i) { a = i; }
};

int main()
{
  MyClass<int> o1(10), o2(9);
  MyClass<double> o3(7.2);

  if(typeid(o1== typeid(o2))
    cout << "o1 and o2 are the same type\n";

  if(typeid(o1== typeid(o3))
    cout << "Error\n";
  else
    cout << "o1 and o3 are different types\n";


  return 0;
}
o1 and o2 are the same type
o1 and o3 are different types
