WebDec 20, 2024 · Iterators are a generalization of pointers that allow a C++ program to work with different data structures in a uniform way. Instead of operating on specific data types, algorithms operate on a range of values as specified by a kind of iterator. Algorithms can operate on any data structure that satisfies the requirements of the iterator. 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.
