#includeOutput: The length of the string is: 5 In this example, we create a string `str` with the value "12345". We then use the `length()` function to get the length of the string and output it to the console. Overall, the `GetLength` function is a very useful tool when working with strings in C++, as it allows you to easily determine the length of a string. Since it is part of the standard C++ library, no additional package library is needed.#include int main() { std::string str = "12345"; std::cout << "The length of the string is: " << str.length() << '\n'; return 0; }
