help with methods

i've been given an assignment, and an entire code. the only thing i have to do is code methods to make the program work. could someone give me an example of what one of these methods would be? i don't understand it. i have a ton to write, but i think once i understand what exactly a method is and how to use it, i can do the rest. this is the code that's given, and this is the assignment

A method is a function.

Basically you need to implement the meat of that class to make it preform the action.

For example

Code:

---

void Time::setTime(int, int, char)
{
}

---

That is how you would create the method for setTime. The insides are up to you to code, since this is a homework assignment.

Feel free to ask if you have further questions.

PS: It worries me that you don't know what a method is especially that your instructor is giving you assignments that deal with classes.

ha, tell me about it. it worries me too. this is my last assignment fortunately. thanks for the tip, i'll get to work on this beast.
