C++-C++ Code Writing Assistant

Example

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

Scenario

Developers use dynamic memory management in C++ for efficient handling of data in resource-constrained applications or in complex data structures like graphs, which may not have a fixed size during runtime.

Example

template<typename T> T add(T a, T b) { return a + b; } int result = add<int>(3, 4); // Using template function

Scenario

Templates allow for type-independent functions and classes, facilitating code reusability and flexibility. This is particularly useful in libraries like STL (Standard Template Library), which provide a rich set of algorithms and containers (like vectors, maps, etc.) operable on any data type.

Example

try { if (someError) throw std::exception(); } catch (std::exception &e) { std::cerr << 'Error occurred: ' << e.what(); }

Scenario

Exception handling in C++ aids in managing errors in a controlled way, particularly in critical software like database systems, where error recovery is just as important as performance.

Example

class Car { public: void accelerate() { /*...*/ } void stop() { /*...*/ } }; Car myCar; myCar.accelerate();

Scenario

C++ supports object-oriented programming which is used to model real-world behavior and relationships in software, simplifying the development of large and complex software systems.
