1. If a 'break' is in an 'if' that is inside a 'do/while' that is inside a 
   'case' that is inside a 'switch' running in a 'while' loop, where does 
   program control go when the break is encoutnered?

Answer1: 
while
  switch
    case '': 
      'do/while'
        if
          break

Break takes to you  out of the current loop.
In this case it would leave the 'do/while', and go to the end of the case
which would be the while loop at the top.

2. If we want a code block to execute one time and then, 
   depending on the outcome of tha test, possibly run more times, 
   what logical control strucite is appropriate?

   'do/while' 

3. What statement tells the program to go back to the beginning of the 
   current loop without processing the remainder of the loop?

Answer: continue

4. Write a program using for loop and
   the variables xx and xsqr to print
   the squares of the integers from 1 to 7.
   The following output is expected.
  1 squared equals 1
  2 squared equals 4
  ...
  7 squared equals 49
 
Answer: see SelfTest1.4.c

5. How many times will the following printf statement be exectued?
#include <stdio.h>
int main(void)
{ 
  short int aa;
  for(aa=1; aa>0; aa++)
  {
    printf("Hi");
  }
  return 0;
} 

Answer:   Infinite

6. Write a program called factor.c that produces the produces
   the following factor output for a series of numbers using
   nested for loops.
  
  1!= 1=1
  2!= 2*1 = 2
  3!= 3*2*1 = 6
  ...
  10!= 10*9*8*7*6*5*4*3*2*1 = 3628800

Answer: see factor.c

7. Write a program that asks an integer between 10 and 20 from the user.
   If the user enteres other values which do not satisfy the condition,
   prints an error message and asks for another number until the 
   condition is met.  Use a do...while loop and if...else structure.
