WebApr 8, 2024 · Syntax of find () The find () function is a member of the string class in C++. It has the following syntax: string::size_type find (const string& str, size_type pos = 0) const noexcept; Let's break down this syntax into its component parts: string::size_type is a data type that represents the size of a string. It is an unsigned integer type. WebJun 30, 2016 · Fast random shuffling. In a random shuffle, you want to take the elements of a list and reorder them randomly. In a “fair” random shuffle, all possible permutations must be equally likely. It is surprisingly hard to come up with a fair algorithm. Thankfully, there is a fast and easy-to-implement algorithm: the Fisher-Yates shuffle.
