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
chardata 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.
