Date Due: Week 5
Use a word processor and give your submissions a professional look.

1. Describe how the break, continue and return provide some of the flexibility of goto statements within the context of structured programming.
   
2. Consider the following program:

   //P
   if(E1)
   	s1();
   else
   	while(E2)
   		if(E3)
   			s2();
   		else
   			s3();
   //Q
   

   
   Write down the pre and post conditions for s1(), s2(), and s3(), so that you can prove that Q is the postcondition for the above program segment given P as the precondition.
   
3. Read the book and briefly compare arrays in Pascal and C++.
   
4. Given int a[7][7]; write down the addresses of a[3][4], a[4][3], a[5][2], a[2][5]. Remember that the array name a is the address of the first element.
