Need help with some c++ code.

These are the compiler errors:
1>c:\users\amber\documents\visual studio 2008\projects\week4_amber nelson\week4_amber nelson\week4_ambernelson.cpp(96) : error C2660: 'Time::setHour' : function does not take 0 arguments

I am just starting to learn and I am a bit confused..

You have written functions to set the hour and set the minute. These functions take an int argument yet when you call these functions you provide no argument at all.

[Amber Nelson]

I don't think I am getting this.. How would I do this? Please explain..I'm stuck.

[whodgson]

I think he is suggesting that the functions setHour() and setMinute()should have int values in each parenthesis.

void Time::setHour(int) 
{ 
cout << "Enter the hour: "; 
cin >> hr; 
} 

Your problem stems from this code. Here the Time::setHour function does not set the hour based an a value passed in. Instead the function asks for an int value which it uses to set the hour without verifying that the value obtained is valid.

Either remove the argument for Time::setHour(int) since you aren't using it or b) use it but do the cin before you call the function.
