c++ The Lock class of the preceding problem has a small problem. It does not support combinations that start with one or more zeroes. For example, a combination of 0042 can be opened by entering just 42. Solve this problem by choosing a different representation. Instead of an integer, use a string to hold the input. Once again, the combination is hardwired. You will see in Section 9.6 how to change it. Complete the following file:
/*** Returns a lowercase version of a user-entered letter* @param kbd* @return lowercase version of user-entered letter*/public static char getNewGuess(Scanner kbd) {return "a";}
Given: string s; int first, last; Write code to repeatedly validate that first is less than last and both first and last are valid indexes of the string s. Then print all characters of the string s from index first to last inclusive. Example Output 1 Enter a string and two indexes: Queensborough 25 eens Example Output 2 Enter a string and two indexes: Science 2 10 Enter a string and two indexes: Science -15 Enter a string and two indexes: Science 2 4 ien
