(Intro to Java) explain the answers to the below questions using step-by-step explanation.   public static void main(String[] args) { boolean hasDigit; Scanner input = new Scanner(System.in); System.out.print("Enter a String: "); String s = input.nextLine(); //call containsDigit here if(hasDigit) { //if hasDigit is true //call printDigits here } else { System.out.println("There are no digits in " + s); } input.close(); }

(C++) 9.  True/False: the strcpy() function will make sure there is enough memory allocated in the destination string before copying C-strings     10.  True/False: when creating a string object, you must dynamically allocate enough bytes to hold the string     11.  Consider the following statement, assuming goAgain is a valid char.  Rewrite it using toupper() or tolower() if (goAgain == 'y' || goAgain == 'Y')     12.  Write a C++ function which accepts a pointer to a C-string as its argument.  It should return the number of words in the C-string.  For example, for the C-string “The Giants won the pennant!” your function should return 5.  You may assume the parameter passed is a pointer to a valid, null-terminated C-string with no newlines or tabs, exactly one space separates each word, and there is at least one word. int wordCounter(char* str)
