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.WebThe strategy is fairly straightforward: call the container's begin function to get an iterator, use ++ to step through the objects in the container, access each object with the * operator ("*iterator") similar to the way you would access an object by dereferencing a pointer, and stop iterating when the iterator equals the container's end iterator.WebC++ Vector Iterators.
