Copy/paste the following code into a file and save as AssignmentsAndCasts.java. Note that it will not compile in its present state because there are symbols that you still need to replace with correct code. See the program output later on this page to know what the variables should equal at the time that they print. 
public class AssignmentsAndCasts {
  
	  public static void main (String[] args){
	    
		     int a = 2;
		     int b = 4;
		     int c = 6;
		     int d = 7;
		     
		     // Replace the ? with +, -, *, /, or % 
		     // and replace N with an appropriate 
		     // int literal to produce the correct result 
		     // in the subsequent println statement

		     a ?= N;
		     System.out.println("a is now " + a);
		     b ?= N;
		     System.out.println("b is now " + b);
		     c ?= N;
		     System.out.println("c is now " + c);
		     d ?= N;
		     System.out.println("d is now " + d);
		     a ?= N;
		     System.out.println("a is now " + a);
		     b ?= N;
		     System.out.println("b is now " + b);
		     System.out.println();
		     
		     // Add decrement or increment operators (prefix or postfix) 
		     // to the variables to produce the correct results

		     System.out.println("c is now " + c); 
		     System.out.println("d is now " + d); 
		     System.out.println("d is now " + d);  
		     System.out.println("a is now " + a); 
		     System.out.println("a is now " + a);
		     System.out.println();
		     
		     // Add casts (and sometimes parentheses) 
		     // to produce the correct results.  Do not change 
		     // the operators or numbers themselves.

		     System.out.println( 9.5 /  3    ); 
		     System.out.println( 50 / 2.5    ); 
		     System.out.println( 27.0 /  3.3 ); 
		     System.out.println( 5.5 *  3.5  );
		     System.out.println();
		     
		     // Replace the ??? with the appropriate expression
		     // (NOT a literal) to produce the correct results
		     //
		     // Each expression will likely involve some char
		     // arithmetic and casting

		     char ch = 'd';
		     System.out.println("ch is now " + ch);
		     ch = ???;
		     System.out.println("ch is now " + ch);
		     ch = ???;
		     System.out.println("ch is now " + ch);
		     ch = ???;
		     System.out.println("ch is now " + ch);  
	    
	  }
  
}
Your task, then, is to follow the directions in the comments in order to make changes to the code that will result in the desired output being printed to the screen. You will use such things as :
  1. Assignment operators (+=, -=, *=, /=, %=)
  2. Increment and decrement operators (++ and --)
  3. Casts: Where you place a type inside of parentheses in front of a value to convert it to a value of a different type
  4. Parentheses - besides the ones you use for casts, also for forcing the order of operations.
  5. Character arithmetic (if you need a refresher, please see the corresponding lecture slides)

Program output, when the program is run, should look like this:

a is now 0
b is now 13
c is now 4
d is now 35
a is now -1
b is now 4

c is now 4
d is now 34
d is now 35
a is now -1
a is now -1

3.0
20
9.0
15

ch is now d
ch is now x
ch is now m
ch is now h
In at least 150 words, please address the following questions:
  1. How did the process of creating these programs go for you?
  2. What were your main challenges and how did you overcome them?
  3. What did you learn that may be of use as you move along in this class?
