Get the first character of a string with an iterator:
string txt = "Hello";

The begin() function returns an iterator (an object that points to a character, similar to a pointer). It points to the first character of the string. Use * in front of the iterator to get the character.
begin() is often used together with end() to loop through the characters of a string.
The begin function is defined in the <string> header file.
