Function Pointer Example — C++ Code
Shows declaring and using function pointers.
#include <iostream>
int add(int a, int b) { return a + b; }
int main() {
int (*func)(int, int) = add;
std::cout << func(2, 3);
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.
