Study Notes
Introduction to Programming
- Programming is the creation of instructions for a computer to execute
- A program is a set of instructions to solve problems effectively
- Programs are written using programming languages (C++, Java, Python, JavaScript)
- Programming languages are translated into machine code
- Programs focus on problem-solving and automation via clear, logical code
Program Concept
- A program is a sequence of instructions for a specific task
- Tasks can range from simple (adding numbers) to complex (software applications)
- Programming focuses on logical code to solve problems
Characteristics of Programming
- Logic and Structure: Programming requires step-by-step instructions to solve problems logically
- Syntax: Each language has specific rules (syntax) for correct code execution
- Efficiency: Programs should use resources (time & space) optimally
- Modularity: Breaking a program into smaller, reusable components
- Maintainability: Writing code that's easy to understand, maintain, and debug
- Debugging and Testing: Thorough testing is needed to ensure all parts are working as intended
Stages in Program Development
- Problem Definition: Clear understanding of the problem to be solved
- Algorithm Design: Step-by-step procedure (algorithm) to solve the problem
- Coding: Writing the program using a programming language
- Testing and Debugging: Running the program and fixing errors (bugs)
- Documentation: Writing clear comments and documentation for future reference
- Maintenance: Making updates or improvements to the program
Algorithms
- A well-defined set of rules or instructions to solve a problem
- Often written in pseudocode or flowcharts before translation to a programming language
Flowcharts
- A graphical representation of an algorithm
- Utilizes symbols (oval, parallelogram, rectangle, diamond) to represent different program steps
Types of Programming Methodologies
- Procedural Programming: Programs comprised of procedures (functions) operating on data
- Object-Oriented Programming (OOP): Based on objects with data and methods
- Functional Programming: Focuses on mathematical functions, avoiding changing data
Brief History of C++
- Developed by Bjarne Stroustrup in the early 1980s at Bell Labs
- Enhanced the C programming language (combining C's efficiency with OOP abstractions)
- Key Milestones: C with Classes (1979) , C++ with classes (1983), first release (1985)& etc.
- Continued improvements and standardization (C++98, C++03, C++11, C++14, etc.)
Application of C++
- System Software Development (operating systems, device drivers)
- Game Development (high-performance games, graphics engines)
- Embedded Systems (small, specialized computing systems)
- Financial Systems (high-frequency trading systems, banking software)
- Scientific Computing (simulations, mathematical libraries)
- Database Management (relational/non-relational database management)
- Cloud/Distributed Systems (distributed applications, middleware software)
- Compilers/Interpreters (translating high-level code to machine code)
- Web Browsers (rendering engines and browser components)
- Artificial Intelligence (machine learning libraries, robotics)
- Software Development Tools (Integrated Development Environments, debuggers)
Compiling and Linking
- Compiling: Converting high-level C++ code to intermediate object code (in steps; preprocessing, Compilation, Assembly)
- Linking: Combining object code with libraries and functions to create an executable file
Errors during Compiling and Linking
- Compile-time errors: Syntax errors and type errors detected during compilation
- Linker errors: Errors related to unresolved functions, variables, or missing libraries detected during linking
Tokens
- Keywords: Reserved words with predefined meaning
- Identifiers: Names used to identify variables, functions, etc.
- Constants: Fixed values that cannot be changed
- Operators: Symbols for performing operations
- Special Symbols: Symbols with specific meanings (e.g., { }, [ ], ; )
- Literals: Fixed values (e.g., numbers, strings)
Keywords, Identifiers, and Constants
- Keywords are reserved words (e.g., int, float, while)
- Identifiers are programmer-defined names(e.g., variable, function names)
- Constants are fixed values(e.g., numerical values or strings)
Basic Data Types
- Built-in data types (int, float, double, char, bool) represent different types of data in C++
User-Defined Data Types
- Structures (group multiple variables)
- Classes (blueprints for creating objects with attributes and methods)
- Enumerations (sets of named integer constants)
Symbolic Constants
- Named constants representing values using
const
keyword or preprocessor directives
Type Compatibility
- Compatibility rules for assigning or comparing values of different types in C++
Reference Variables
- An alias for another variable.
- Used to access the original variable using another name
Operators
- Symbols performing mathematical, logical, or relational operations in C++
Scope Resolution Operator
- Used to define the scope of a variable, function, or class, especially when there are ambiguities
Member Dereferencing Operators
- Operators to access members of a class or structure when using pointers to objects or structures (dot operator, arrow operator, pointer-to-member operator)
Memory Management Operators
-
new
operator: Dynamically allocates memory -
delete
operator: Deallocates previously allocated memory
Manipulators
- Tools for formatting input and output streams (e.g.,
endl
,setw
,setprecision
)
Type Cast Operator
- Converts data types
Functions in C++
- Building blocks of a program; reusable code segments
- Main function execution entry point
- Parameters: Values passed to functions
- Return Values: Results returned by functions.
- Parameter Passing (Values, References, Addresses)
Function Prototyping
- Declaring a function before its definition
- Allows compiler to check function calls and ensures correct usage
Inline Functions
Default Arguments
- Functions with optional parameter values (default values)
- Allows to call function with less parameters
Constant Arguments
- Parameters preventing modifications inside a function
Function Overloading
- Defining multiple functions with the same name but different parameters
- Increases code readability and organization.
Functions with Arrays
- Functions that accept arrays as parameters
- Arrays are passed as pointers to the first element.
