In C++, calling a virtual function inside a constructor or destructor is dangerous and should generally be avoided. Following are the reasons to avoid calling: When a constructor (or destructor) is running, the object is not fully built (or fully destroyed). ... Read More

What is an Assertions in C/C++? An assertion is a statement used to test assumptions made by the program. When an assertion fails, the program displays an error and stops. This is mainly used for debugging. In C and C++, assertions are handled using the assert() macro defined in the ... Read More

What is Conversion Operator Conversion operators are a type of operator overloading in C++. These operators are commonly known as type-cast operators. They enable a class or structure to specify how an object should be converted into another data type. Sometimes we need to convert concrete-type objects to some other ... Read More

In C++, we allocate the memory dynamically using the new operator. But there is a special version of this operator known as placement new operator. The new operator performs two things. It allocates memory, and then constructs an object in allocated memory. But for the placement new operator, it ... Read More

Yes, C++ virtual functions can have default parameters. The default parameter is the value provided during function declaration, such that the value can be automatically assigned if no argument is passed to them. In case any value is passed the default value is overridden and becomes a parameterized argument. Virtual ... Read More

Searching for a substring within a short text is a common operation in many C++ programs, like as small-scale text editors, command line utilities, and education projects. So, in this article, we will implement a string search algorithm for short text sizes. Importance of String Search String search algorithms find ... Read More

Array Class In C++, the array class is part of the standard library and is known for its fixed size. The C++ array class, introduced in C++11, offers a better alternative to C-style arrays. The following are the advantages of the array class over a C-style array: ... Read More

The median is defined as the middle value of a sorted list of numbers, and the middle value is found by ordering the numbers in ascending order. Once the numbers are ordered, the middle value is called the median of the given data set. Here, in this article, we have ... Read More

Queue The queue is a linear data structure that follows the First-In-First-Out (FIFO) operation. Where insertions are done at one end (rear) and deletions are done from another end (front). The first element that is entered is deleted first. Following are the stack operations: EnQueue ... Read More

The fork() system call is used to create a process commonly known as a child process if the fork() returns 0. Otherwise, the created process is known as the parent process. All processes created with fork() execute in parallel. But what if we want the last process to be executed ... Read More
