Powerful and Fast Programming Language
C++ is a powerful, fast, and flexible programming language. It is the ideal choice for system programming, game development, and applications requiring high performance.
Development process and important milestones of the language
Bjarne Stroustrup laid the foundations of C++ by adding the concept of classes to the C language at Bell Labs.
The language was officially named "C++". The ++ operator symbolized that it was an improved version of the C language.
C++ was standardized by ISO for the first time. This version is known as C++98 and defined the basic features of the language.
C++11 standard was released. This update introduced modern features such as lambda functions, auto keyword, and smart pointers.
C++20 standard was released, adding important features such as modules, concepts, and coroutines, making the language even easier to use.
Core features that make C++ powerful and flexible
Strong object-oriented programming support with classes, inheritance, and polymorphism.
class Car {
private:
string brand;
public:
void start() { ... }
};
Rich standard library support with data structures, algorithms, and iterators.
#include <vector>
#include <algorithm>
vector<int> nums = {3, 1, 4, 1, 5};
sort(nums.begin(), nums.end());
Safe memory management with manual memory control and modern smart pointers.
#include <memory>
auto ptr = std::make_unique<int>(42);
auto shared = std::make_shared<string>("Hello");
Modern syntax with lambda functions, auto keyword, and range-based for loops.
auto lambda = [](int x) { return x * 2; };
for(const auto& item : container) {
cout << item << " ";
}
Maximum performance with low-level memory access and optimizable code.
int* array = new int[1000];
for(int i = 0; i < 1000; ++i) {
array[i] = i * 2;
}
Portable code that can run on different operating systems and hardware.
#ifdef _WIN32
// Code for Windows
#elif defined(__APPLE__)
// Code for macOS
#else
// Code for Linux
#endif
