Algorithm Transform Example — C++ Code

Uses std::transform to modify elements of a container.

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
	std::vector<int> v = {1, 2, 3};
	std::transform(v.begin(), v.end(), v.begin(), [](int x){ return x * 2; });
	for (int n : v) std::cout << n << ' ';
	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.
