#includeThis code snippet declares a string variable "str" and initializes it to "Let's code!". The end function is used to get an iterator pointing to the end of the string. A for loop is used to iterate over the characters in the string from the beginning to the end using the iterators. The total count of characters is printed at the end of the loop. The std basic_string end function is part of the C++ Standard Library.#include using namespace std; int main(){ string str = "Let's code!"; int count = 0; for (auto it = str.begin(); it != str.end(); ++it){ ++count; } cout << "Total characters: " << count << endl; return 0; }
