C++ Programming Definitions Quiz

Identifiers in C++

• Identifiers are used to name variables, functions, and labels in C++.

Case Sensitivity

• C++ is case-sensitive, meaning that uppercase and lowercase letters are treated as distinct characters.

Data Types

• The char data type in C++ is used to hold a single alphanumeric character enclosed in single quotes.

Components of a Programming Language

• A programming language consists of syntax, semantics, and pragmatics.

Purpose of a Programming Language

• The purpose of a programming language is to write instructions that a computer can execute.

Basic Structure of a C++ Program

• The basic structure of a C++ program includes preprocessor directives, functions, and statements.

Basic Output in C++

• The syntax for basic output in C++ is cout << "output";.

Arithmetic Operators

• Arithmetic operators in C++ include +, -, *, /, %, and others.
• The % operator represents the modulus (remainder) operation.

Arithmetic Expressions

• Arithmetic expressions in C++ are evaluated according to the operator precedence rules.

Combined Operators

• The combined operator value += 5; represents the addition of 5 to the value of a variable.

Increment and Decrement Operators

• Increment and decrement operators are used to increment or decrement a variable by 1.
• The purpose of using increment and decrement operators is to simplify the code and improve readability.

Logical Operators

• Logical operators in C++ include &&, ||, and !.

Shifting Operators

• Shifting operators in C++ include << and >>, which represent left shift and right shift operations.

Notation

• The '++N' or '--N' notation represents a pre-increment or pre-decrement operation.
• The 'N++' or 'N--' notation represents a post-increment or post-decrement operation.

Flowcharts

• The purpose of a flowchart is to represent the flow of a program's execution.
• A flowchart consists of symbols, such as rectangles, diamonds, and arrows, which represent different elements of the program.

Flowchart Symbols

• The diamond symbol in a flowchart denotes a decision to be made, where the program must choose along one of the two routes.
• The rectangle symbol represents a process or an action in a flowchart.
• Connectors in a flowchart are used to connect the different symbols and represent the flow of control.
• A flowchart used for calculating the area of a triangle demonstrates the use of decision-making and iteration in a program.
• The primary function of a flowchart in programming is to visualize the program's logic and flow.
