Here is a simple example that uses typeid

 

#include <iostream>
#include <typeinfo>
using namespace std;
class myclass1 {
};
class myclass2 {
};
int main()
{
  int i, j;
  float f;
  char *p;
  myclass1 ob1;
  myclass2 ob2;
  cout << "The type of i is: " << typeid(i).name();
  cout << endl;
  cout << "The type of f is: " << typeid(f).name();
  cout << endl;
  cout << "The type of p is: " << typeid(p).name();
  cout << endl;
  cout << "The type of ob1 is: " << typeid(ob1).name();
  cout << endl;
  cout << "The type of ob2 is: " << typeid(ob2).name();
  cout << "\n\n";
  if(typeid(i) == typeid(j))
    cout << "The types of i and j are the same\n";
  if(typeid(i) != typeid(f))
    cout << "The types of i and f are not the same\n";
  if(typeid(ob1) != typeid(ob2))
    cout << "ob1 and ob2 are of differing types\n";
