To return in a method, return as you would in the main method.
int hello(){ return 0; }
As for parameters, you may initialize them in three ways.
int hello (parameters); int goodbye (int good, int bye); int howAreYou (int, int);
If you want to save the value of what a function returns, store it into a variable.
Mini Project
Create a method, outside of the main method, that adds an “ !“ to a given char array (char[]). Remember the space!
