Exception Handling — C++ Code

Shows basic try-catch exception handling in C++.

#include <iostream>
#include <stdexcept>
int main() {
	try {
		throw std::runtime_error("Something went wrong");
	} catch (const std::exception& e) {
		std::cout << "Caught exception: " << e.what() << std::endl;
	}
	return 0;
}

C++ Language Guide

General-purpose, multi-paradigm programming language extending C with object-oriented features, strong type safety, and zero-cost abstractions for building high-performance applications.

Primary Use Cases

▸Game development (Unreal Engine, custom engines)
▸High-frequency trading systems
▸Desktop applications
▸Operating system components
▸3D simulations and physics engines
▸Embedded and automotive software
▸Large-scale enterprise backends

Notable Features

▸Object-oriented programming with classes
▸Zero-cost abstractions
▸Templates for generic programming
▸Standard Template Library (STL)
▸RAII memory management
▸High-performance compiled binaries

Origin & Creator

Created by Bjarne Stroustrup at Bell Labs, first released in 1985. Originated as 'C with Classes' (1979), later renamed to C++ (1983). Evolved through major standards: C++98, C++03, C++11, C++14, C++17, C++20, C++23 - each introducing features like templates, STL, auto, lambdas, modules, and concepts.

Industrial Note

Dominates game engines, AAA games, high-frequency trading platforms, large-scale systems, real-time simulations, 3D engines, embedded systems, and performance-critical enterprise software.

Quick Explain

▸C++ is a compiled, high-performance language supporting procedural, object-oriented, and generic programming.
▸It offers fine control over memory with RAII and manual management.
▸Widely used for performance-critical systems, games, engines, and large-scale applications.

Core Features

▸Classes, objects, inheritance, polymorphism
▸Templates and metaprogramming
▸Smart pointers for memory safety
▸Namespaces and modules
▸Operator overloading

Learning Path

▸Syntax and classes
▸STL containers and algorithms
▸OOP and inheritance
▸Templates and generics
▸Smart pointers and RAII
▸Concurrency and systems

Practical Examples

▸Implement a vector using dynamic memory
▸Build a multithreaded server using std::thread
▸Create a class hierarchy for shapes
▸Develop a mini game engine component

Comparisons

▸Higher-level than C
▸Faster and lower-level than Java
▸More flexible but complex vs Rust
▸More performant than Python

Strengths

▸High performance close to C
▸Massive ecosystem and libraries
▸Supports multiple paradigms
▸Deterministic memory cleanup with RAII
▸Industry-standard for games and engines

Limitations

▸Complex syntax and learning curve
▸Long compile times
▸Undefined behavior pitfalls
▸Requires careful memory management

When NOT to Use

▸When rapid development is needed
▸For small scripts
▸For simple web apps
▸When memory safety must be guaranteed automatically

FAQ

▸Why is C++ still relevant?
▸C++ remains essential for systems requiring high performance, real-time control, and zero-cost abstractions. It powers AAA games, operating systems, browsers, and high-frequency trading systems.
▸Is C++ good for beginners?
▸It can be challenging but teaches strong fundamentals in OOP, memory, and systems programming. Good for serious learners.
▸How do I avoid memory leaks in C++?
▸Use smart pointers (unique_ptr/shared_ptr), follow RAII, minimize raw pointers, and use tools like Valgrind.
▸How is C++ different from C?
▸C++ adds OOP, templates, exceptions, RAII, and STL while maintaining compatibility with C but offering higher abstractions.

30-Day Skill Plan
