C++-C++ Programming Assistance

Example

class Animal { public: void animalSound() { std::cout << "The animal makes a sound\n"; } }; class Pig : public Animal { public: void animalSound() { std::cout << "The pig says: wee wee\n"; } };

Scenario

OOP allows for models of real-world entities such as animals in a farm simulation where different animal types inherit properties from a generic animal class but have their own specific sounds.

Example

template <typename T> T add(T a, T b) { return a + b; } // Usage: add<int>(10, 20); add<double>(1.1, 2.2);

Scenario

Template programming enables functions and classes to operate with generic types. This allows for writing a single function or class to work with different data types. For example, implementing a 'add' function that can add numbers of any type.

Example

int* ptr = new int; *ptr = 7; delete ptr;

Scenario

Direct control over memory allocation and deallocation is crucial in developing performance-critical applications, like game engines, where efficient resource management is critical.

Example

#include <vector> std::vector<int> vec = {1, 2, 3, 4, 5}; for(int i : vec) { std::cout << i << ' '; }

Scenario

STL provides a rich set of template classes and functions to manipulate data structures. For example, using a vector for dynamic arrays that can change size.
