typeid Can Be Applied to Template Classes
#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);
cout << "Type of o1 is ";
cout << typeid(o1).name() << endl;
cout << "Type of o2 is ";
cout << typeid(o2).name() << endl;
cout << "Type of o3 is ";
cout << typeid(o3).name() << endl;
cout << endl;
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;
}
