Study Notes

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.
