A useful tool for string operations is regex. This may be found in virtually all high-level current programming languages, including C++. Regular expressions (Regex) are utilized as general-purpose search patterns. For instance, by constructing a straightforward string known as a regular expression, we may implement password validation logic with at ... Read More

Strings are a collection of characters. We can also say them as character arrays. Considering an array of characters as strings, the strings have specified indices and values. Sometimes we can perform some modification on strings, one such modification is replacing characters by providing a specific index. In this article, ... Read More

Lists in C++ are containers the same as vectors, but list implementation is based on doubly linked lists compared to the array implementation of vectors. Lists generally do not contain elements in contiguous locations, the elements of a list are distributed throughout the memory. Lists offer the same constant time ... Read More

Displaying star patterns in different shapes, like pyramids, squares, and diamonds, is a common part of basic programming and logic development. We faced various problems involving stars and numerical patterns as we studied looping statements in programming. This article will demonstrate how to print an X or a cross using ... Read More
