Memory Leaks Memory leaks occur when a program fails to deallocate dynamically allocated heap memory that is no longer needed, resulting in permanent memory wastage during runtime. This does not mean physical memory is lost, but that the application loses all references to an allocated memory block,...
Polymorphism enables objects of different classes to be treated as objects of a common base class, allowing the same function call to produce different behaviors depending on the object type. For example, consider a ticket purchasing system where a regular person pays full price, a student pays half...
Reading Images In OpenCV, the cv::imread() function is used to load images from a file. This function returns a cv::Mat object, which is the primary data structure in OpenCV for storing image data. // Load a color image cv::Mat imgData = cv::imread("sample_image.png", cv::IMREAD_COLOR); Th...
Inline Functions Inline functions are a compiler optimization technique that replaces function calls with the function body at compile time. This is a trade-off where code size may increase to reduce execution time overhead. Characteristics The inline keyword serves as a suggestion to the compiler;...
Traditional error handling in C relies on return values or global variables to indicate function execution status, but this approach has significant drawbacks. Terminating the program using functions like assert or exit leads to abrupt crashes, disrupting stability. For example, a calculator should...
Boolean Type A boolean type is used for logical evaluations, such as condition checks, flow control, and logical operations. Key Points bool is a data type that can hold one of two values: true or false. Example definition: bool isActive = true; It occupies 1 byte of memory. Boolean variables can be...
A high-precision integer class enables arithmetic operations on numbers exceedign standard integer limits, icnluding handling negative values. This class uses a fixed-size array to store digits, with M defining the maximum length of the string representation. It overloads operators for addition, sub...
Virtual destructors in C++ are specialized member functions that ensure proper cleanup of derived class objects when they are destroyed through base class pointers or references. This mechanism is essential for polymorphism, guaranteeing that when an object is deleted via a base class reference, the...
Linear structures represent a fundamental and widely used category of data structures. Their defining characteristic is a linear relationship between elements. Common implementations like dynamic arrays, linked lists, stacks, and queues all fall under this category. While they share the property of...
T1 - Reading Plan Problem: A book has (n) pages. On the first day, a person reads (x) pages. Each subsequent day, they read (y) pages more than the previous day. How many days are needed to finish the book? Input: Three integers (n), (x), (y) ((20 \le n \le 5000, 1 \le x, y \le 20)) separated by spa...
