Range based for loop is relatively new in C++. It provide a neat way to iterate a sequence. Refer the following code from the read: // range-based for loop #include #include using namespace std; int main() { } string str {"Hello!"); for (char c: str) { cout << "[" << < << "]"; } cout << '\n'; What is the type of the range here? I highly recommend to click the gear icon on right in the read to test it out. O char C No answer text provided. str "Hello!" Ostring
