Announcements
  • Any clarifications or corrections to the assignment will be stated here.
  • Send email questions for this assignment to Jayaram at .
  • 2/2/05 To output in hex, you must display a digit at a time starting with the MOST significant digit since character output is left to right. Doing this takes a bit of thought since you do not have arrays or string objects. Hint: consider implementing the "subtract powers of" algorithm for base 16 like done in lecture for base 2.
  • 2/2/05 A1 hand-in directories are now open.
  • 2/4/05 SAL allows you to mix .word and .byte types in calculations. The cvt (i.e. convert) instruction is for integer to float and float to integer conversions only, which aren't used in A1.
  • 2/7/05 Printing the output in hexadecimal is the hardest part of this assignment. If you are unable to figure this out, show the hex output in least significant to most significant digit order for partial credit on this part of the program.
1: Multiple Choice Questions 10 points
I strongly recommend that you first do these multiple-choice problems without using the simulator, a calculator, or referring to your notes. This is good practice for the exam and can help you gauge how well you know the course material. After determining your answer, then check your work.

    label_2: blez x2, label_3
             put  x2
             sub  x2, x2, 1
             b    label_2
    label_3: put  newline      #assume newline stores a '\n' character 
             add  x1, x1, 1
             b    label_1
    label_4: done

       321
       432
    E. none of the above

  4. The value 101011 base 2 is equivalent to:
    A. 211.1 base 3
    B. 25.1 base 8
    C. 21.75 base 10
    D. 15.7 base 16
    E. all of the above

  5. Which one of the following statements is false?:
    A. The decimal point is called the radix point in general.
    B. A single magnitude may be represented by many different numbers.
    C. The accuracy of a computation is same as the precision of the computing machine used.
    D. Accuracy quantifies the difference between the measured or computed value and the actual or true value.
    E. The precision of a computing machine is fixed by the maximum number of significant digits that can be represented and computed by that machine.

2: Written Questions 25 points

I strongly recommend that you first do these written problems without using the simulator, a calculator, or referring to your notes. This is good practice for the exam and can help you gauge how well you know the course material. After determining your answer, then check your work.

To indicate a repeating fraction in your text file answers for the questions in this part of the assignment follow the fraction with ... as in 1.23... which means 1.2323232323 and so on.

  1. (9 points) Write the SAL equivalent of the following Java code fragment:
    switch (c1) {
      case 'A':
      case 'a': i1 = 11; break;
      case 'b': i1 = 22; break;
      default:  i1 = 33;
    }
    System.out.print(i1);
    
  2. (12 points) Convert numbers from the given radix to fill in the following table.
    Decimal       Binary      Octal     Hexadecimal
    -------      -------      -----     -----------
    37
                 1011111
                              0673
                                        0x20e
    
  3. (4 points) Give a base 5 representation for the value 123.3 base 4.
3: Programming Work 65 points
Write a SAL program that reads in three non-negative integers that are entered by the program user. The first is a decimal integer in the range from 2 to 16 inclusive. It is used to specify the base of the second and third integers, which represent the dimensions (width, length) of a surface. The program uses these integers to calculate the area of that surface, which is displayed in bases 10 and 16.

Note that we are completely ignoring units in this program. We'll assume that the units for the width and length integers are the same so that the area calculation is valid.

Here's a sample execution of the program (user input in bold):

This program prints the area of a surface.

Enter the integers' base (in decimal): 2
Enter the integer length: 100
Enter the integer width: 100
The area in decimal is 16 units.
The area in hexadecimal is 0x10 units.

Here's another sample execution of the program (user input in bold):

This program prints the area of a surface.

Enter the integers' base (in decimal): 10
Enter the integer length: 12
Enter the integer width: 4
The area in decimal is 48 units.
The area in hexadecimal is 0x30 units.

Before submitting your programming work, make sure that you have followed the Standards for Grading Programs. Especially make sure you've documented your program and have organized it into procedures.

Regarding Errors and Input: As specified in the grading standards for programs, your programs must handle invalid input in a reasonable manner. For this assignment, if invalid input is entered for the base specified, display a clear error message and ask the user to re-input the value. You do not need to worry about the problem of integer overflow. For digits values 10 - 15 you only need to have your programs handle lowercase (a-f) though a better progrm would be able to accept both uppercase and lowercase.

WARNING:  b, j, m, M  are predefined and will cause headaches if you use them as labels. As a rule of thumb I suggests that you use names that are at least 2 characters long, e.g., c1 or i1.

What to Submit
You are to turn in the following by the due date and time. Refer to the assignments page for information about how to submit your written and programming work. Also refer to the late policy if necessary.
