I am new to learning classes/constructors/etc... and between the two programs that I have written thus far that use classes and everything that goes in them I have been getting the same error and cannot figure out how to solve it. The error for the code below reads:

Can anyone point me to where the problem is and how to go about fixing it?Code:main.cc: In function 'int main()':main.cc:7:23: error: no matching function for call to 'MyTime::MyTime(int, int)' MyTime.h:9:3: note: candidates are: MyTime::MyTime(int&, int&) MyTime.h:8:3: note: MyTime::MyTime() MyTime.h:4:13: note: MyTime::MyTime(const MyTime&) main.cc:28:18: error: no matching function for call to 'MyTime::add_hours(int)' MyTime.h:13:7: note: candidate is: int MyTime::add_hours(int&) main.cc:33:20: error: no matching function for call to 'MyTime::add_minutes(int)' MyTime.h:14:7: note: candidate is: int MyTime::add_minutes(int&)

Code:
