Lambda for STL Example — C++ Code
Uses lambda to modify elements in a vector.
#include <iostream>
#include <vector>
#include <algorithm>
int main() {
std::vector<int> v = {1, 2, 3, 4, 5};
std::for_each(v.begin(), v.end(), [](int& n){ n *= 2; });
for (const auto& 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.
