The Proxy design pattern provides a surrogate or placeholder for another object to control access to it. This approach enables flexible object substitution while maintaining functional entegrity, similar to how a clothing retailer can switch between different brands while continuing to serve custome...
Encapsulation and Access Control C++ encapsulation restricts direct access to internal state, exposing only validated interfaces. By default, class members are private, whereas struct members are public. Access specifiers (private, protected, public) define visibility boundaries, with protected beco...
Binary search is an efficient algorithm for locating a target value within a sorted sequence. The standard implementation returns the position of any matching element, but may not identify the first occurence when duplicates exist. int binarySearch(int left, int right, int target) { int result = -1;...
Function Signature and Requirements The sorting utility is provided by the <algorithm> header. The function accepts a starting iterator, an ending iterator, and an optional comparison predicate. Without a custom predicate, elements are ordered in ascending sequence. This utility is generic and...
C++ emerged from Bell Labs in 1979, developed by Bjarne Stroustrup as an extension of the C language, incorporating object-oriented principles. It is characterized by high performance, low-level control, and object-oriented features. The evolution of C++ reached a significant milestone with the rele...
Introduction Hello everyone, this is Xiamu's C++ study note. Here, I will explain the vector container from the C++ STL. This blog is suitable for those who are learning vector or want to deepen their understanding of STL. We will not only introduce the various features of vector but also implement...
Quest Data Structure The core quest structure defines mission parameters including objectives, rewards, and completion conditions: USTRUCT(BlueprintType) struct FQuest { GENERATED_BODY() UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Task") FString QuestName{ "Empty" };...
Development Environment and Project Configuration When managing multiple source files within a single C++ project using CMake, you can automate the generation of executables for each .cpp file found in the source directory. This is particularly useful for competitive programming or educational modul...
Creating Dynamic Libraries Windows DLL Development To create a Windows dynamic link library, start by establishing a DLL project. The core functionality is implemented in the source file: #include "framework.h" extern "C" __declspec(dllexport) int addValues(int x, int y) { return...
Palindrome Date Calculation The code below checks for palindrome dates between two given date strings. #include<iostream> #include<cstring> #include<sstream> using namespace std; string data1; string data2; int cnt; int y1,m1,d1; int y2,m2,d2; int day[] = {31,28,31,30,31,30,31,31,3...
