C++-C++ Learning Platform

Example

int *ptr = new int(10); // dynamic allocation delete ptr; // deallocating memory

Scenario

C++ allows explicit control over memory resources, which is critical in system programming where efficient resource utilization is key. This capability enables developers to write highly efficient code for systems that have limited memory resources, like embedded systems.

Example

class Car { public: void accelerate() { // code to accelerate } };

Scenario

C++ supports object-oriented programming (OOP) features like classes, inheritance, and polymorphism. This facilitates the development of organized, modular code for complex software systems like computer simulations or games, where different modules can interact through well-defined interfaces.

Example

template<typename T> T add(T a, T b) { return a + b; }

Scenario

Template metaprogramming in C++ enables writing flexible and efficient code that can work with any data type. It's widely used in creating high-performance libraries, such as those for numerical computation, where operations need to be generalized across different data types.

Example

#include <vector> std::vector<int> vec; vec.push_back(1);

Scenario

The STL is a powerful set of C++ template classes to provide general-purpose classes and functions with templates that implement many popular and commonly used algorithms and data structures like vectors, lists, queues, and stacks. This is used extensively in software engineering for data processing and manipulation.
