Answer 2

Hmm.. sounds like homework, but I'll give you this one for free

Solution: (Java)

import java.util.Scanner;

class MyClass{

public static void main(String[] args){
Scanner sc = new Scanner(System.in);
String secret = sc.nextLine();
int secretNum = (secret.length() * 2) + 7;
System.out.println("There are " + secretNum + " characters in your secret message");
}
}

Use scanner to get the input from the user. Then use the string that you get from the user and print out its length. You should know how to do math so thats easy.
