C++-trial for C++ guidance

Example

class Animal { public: virtual void sound() = 0; }; class Dog : public Animal { public: void sound() override { cout << "Bark"; } };

Scenario

OOP in C++ is used extensively in scenarios requiring modularity and code reuse. For example, in game development, different game entities like characters, enemies, and items can be represented as classes, allowing for easy extension and maintenance.

Example

template<typename T> T add(T a, T b) { return a + b; } int main() { cout << add(3, 4); cout << add(3.5, 4.5); }

Scenario

Generic programming in C++ is utilized to write flexible and reusable code. For instance, template functions and classes can handle different data types, such as in a library where sorting algorithms need to work with various data types like integers, floats, or custom objects.

Example

#include <vector> #include <algorithm> std::vector<int> vec = {1, 2, 3, 4}; std::sort(vec.begin(), vec.end());

Scenario

STL provides a collection of template classes and functions for common data structures and algorithms. In financial software development, STL components like vectors, maps, and algorithms can be used to manage and process large datasets efficiently.
