C++ Basics Fundamentals of Computer Science

Outline  Part 1:  Overview  Program Structure  Part 2:  Variables and Data Types  Operators  Basic Input/Output (I/O)  Part 3:  Control Structures  Functions

Control Structures  Conditional (if) Statement  Example:

Control Structures  Selection Statement  Example:

Control Structures  Iteration: while loop  Example:

Control Structures  Iteration: do-while loop  Example:

Control Structures  Iteration: for loop  Example:

Control Structures  Iteration: range-based for loop  Example:

Functions  Function Syntax:  Example:

Functions  Example with no return type:

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

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

Functions  Default Values in parameters

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:
