Assignemnt 1. If the following code is included in a program what will
  the outcome be and why?

  aa=6; 
  if ( aa <= 5 )
    printf ("The value of aa"); 
  printf("is less than or equal to 8"); 
  else
    printf("aa is greater than 5");
 
Answer:  compile error. error: expected expression before else
         you need braces between the if and the else
         when you have more than one statment between.

Assignment 2. Explain how the following code fragments work:
a)
  gg=' '; // assign a space to variable gg 
          // assumed to be a previously declared char variable
  while (  (aa=getchar() ) != gg ) // get character from standard in
                                   // assign result ing value to address of aa
                                   // while the value in aa the same as the value of gg, 
                                   // execute the next command
  printf("%c", aa); // print the ascii value in aa

b) 
  switch(bb) // consider the value in bb for this switch satment
  case 'A': mmnnoo(); //  if bb holds ascii value 'A' , call function mmnnoo
            break;    // exit switch block

3) In the SELFTEST, you completed the digitconverter.c and evenorodd.c 
   programs. Explain how each works. Include sample output with our 
   verison of the programs.

  Please see comments in attached programs
  Ran:     who | ./digitcounter
  Output:  The number of digits input: 79

  Ran: ./evenorodd 
  Input:  Enter an integer: 20
  Output: The number 0 is even
  Input:  Enter an integer: 21
  Output: The nubmer 0 is odd
  Input:  Enter an integer: 20.5
  Output: That is not an integer: 20.500000
  Input:  Enter an integer: 0
  Output: Zero is not even or odd. it's zero
