Introduction to C++ Lesson 1 Flashcards

Vocabulary-style flashcards covering the fundamental concepts of C++ programming, including variables, program structure, and naming conventions.

Computer programming

The process of creating a Program.

Program

A set of routines or instructions to be executed in devices or machines using a programming language.

Programming Language

A medium or tool used to create a program.

Declaration Area

The section in a program where the variables are being declared.

Variables

Names that refer to a section of memory in which data can be stored.

Global variable

A variable that can be used throughout the program, accessible by both the main program and functions.

Local variable

Variables that are declared inside a specific function.

Preprocessor Directive

Instructions such as #include that provide standard input/output library functions like $cin$ and $cout$.

Constant Declaration

Using #define (e.g., #define PI 3.1416) to ensure a value is automatically replaced every time its name appears in the code.

Variable Naming Rules

Rules stating names must start with a letter or underscore, can contain letters/numbers/underscores, must not be reserved keywords, and that case is significant (e.g., $num$ vs $Num$).

Data Types

Determines the values that a variable can contain and the operations that can be performed on them.

$31$ Characters

The number of characters considered important in variable naming according to the lecture notes.
