Study Notes
Overview of Computer Science Using C++
- Definition: Computer science is the study of algorithms, data structures, and the principles of computing.
- C++: A high-level programming language that supports both procedural and object-oriented programming.
Key Concepts
-
Basic Syntax
- Variables: Declaration, initialization, and types (int, float, char, etc.)
- Operators: Arithmetic, relational, logical, and bitwise operators.
- Control Structures: if, switch, for, while, do-while.
-
Data Structures
- Arrays: Fixed-size collections of elements.
- Strings: Collections of characters, often used with
std::string
. - Structures: User-defined data types using the
struct
keyword. - Standard Template Library (STL): Includes vectors, lists, maps, and sets.
-
Functions
- Definition and Calling: Standard function syntax and parameter passing (by value, by reference).
- Overloading: Functions with the same name but different parameters.
- Recursion: Function that calls itself to solve problems.
-
Object-Oriented Programming (OOP)
- Classes and Objects: Blueprint for creating objects (instances of classes).
- Encapsulation: Bundling data and methods that operate on data within the class.
- Inheritance: Mechanism where one class can inherit the properties of another.
- Polymorphism: Ability to process objects differently based on their data type or class.
-
Memory Management
- Stack vs Heap: Stack for static memory allocation, heap for dynamic allocation.
- Pointers: Variables that store memory addresses, crucial for dynamic memory management.
- Smart Pointers:
std::unique_ptr
,std::shared_ptr
for automatic memory management.
-
Algorithms
- Sorting Algorithms: Bubble sort, quicksort, mergesort.
- Searching Algorithms: Linear search, binary search.
- Complexity Analysis: Big O notation to describe algorithm efficiency.
-
Exception Handling
- Try-Catch Blocks: Handling errors gracefully using exceptions.
- Throwing Exceptions: Mechanism to signal an error or unexpected behavior.
-
File I/O
- Stream Classes: Input and output streams for file handling (
fstream
,ifstream
,ofstream
). - Reading and Writing: Techniques for reading from and writing to files.
- Stream Classes: Input and output streams for file handling (
-
Development Tools
- Integrated Development Environments (IDEs): Visual Studio, Code::Blocks, Eclipse.
- Version Control: Basics of Git for tracking changes in code.
Best Practices
- Code Documentation: Writing clear comments and documentation for code readability.
- Code Reusability: Utilizing functions, classes, and libraries to avoid redundancy.
- Testing and Debugging: Strategies for unit testing and using debuggers.
Conclusion
Understanding C++ within computer science provides a foundation for software development, algorithm design, and system-level programming. It combines theoretical knowledge with practical application, essential for a career in technology.
