[intv] Operator overloading

//---------------main.cpp-----------
//Problem: Example of operator overloading.
//Save as:

#include <iostream>
using namespace std;

class skTime{
  friend ostream &operator<< (ostream&, const skTime &);
private:
  int min, hr, sec;
public:
  skTime(int, int, int); //constructor
  void printTime(void);
};

skTime::skTime(int a, int b, int c){
  hr = a;
  min = b;
  sec = c;
}

void skTime::printTime(void){
  cout << "Func:" << hr << ":" << min << ":" << sec << endl;
}

ostream &operator<< (ostream &output , const skTime &T){
  output << "Operator overloaded:" <<  T.hr << "-" << T.min << "-" << T.sec;
  return output;
}



int main(){
  skTime T(10, 10, 10);
  T.printTime();
  cout << T << endl;

}
