SLIDE 9

Functions

 Function Syntax:  Example:

SLIDE 10

Functions

 Example with no return type:

SLIDE 11

Functions

 Pass by Value  vs.  Pass by Reference:

SLIDE 12

Functions

 Pass by Value  Pass by Reference:  Safe and Efficient:

SLIDE 13

Functions

 Default Values in parameters

SLIDE 14

Functions

 Declaring Functions:

 Any identifier – function or variable – must be declared before it is used  So… can define function above main() function OR  Can use a function declaration before code:
