Assignments

Assignment 1: Kaplan, pp 32-33, Exercises 2.1 through 2.4

Assignment 2: Kaplan, pp 61-63, Exercises 3.1, -2, -3, -4, -7, -8, -9

Assignment 3: Build-A-Boat program

Assignment 4: Payroll program

Assignment 5: Overflow program

Assignment 6: K&R

Write a program that meets the requirements of Kernighan & Richie (K&R) Exercises 1-3 and 1-4 (page 13). In other words, write a program that uses a for loop to print out a table for converting from Celsius to Fahrenheit. There should be a heading above the table. The output should be cleanly formatted like the example outputs shown on pages 11 and 13.

E-mail the source code of the C program to the instructor by the due date.

Assignment 7: Array Functions in C

Assignment 8: Variable length arrays in C

Modify Assignment 7 as follows:

• Modify the functions to take a second argument: an integer giving the actual number of elements in the array (the effective length instead of the maximum length).
• Replace the initialized array with an empty one of at least 100 elements
• Write a 'sentinel loop' to collect positive integers and store them in successive locations in the array. When the user types a negative number, exit the loop.
• Run the functions against this array, but only use the actual number of elements read in by the sentinel loop.

Assignment 9: History Paper

Assignment 10: Program to count word sizes

Assignment 11: Program to look up phone numbers

Assignment 12: Program to display scaled data

Assignment 13: Matlab Indexing (Exercises in Kaplan)

• Exercises 4.1 through 4.6, and 4.8, pages 85-86. Be sure to construct expressions that work with variables as opposed to simply providing numerical answers.
• E-mail the results to the instructor.

Assignment 14: Matlab Arrays and scripts (Exercises in Kaplan)

• Exercise 5.2, page 109
• E-mail the .m script to the instructor..

Assignment 15: Matlab Scripts (Exercises in Kaplan)

• Exercise 5.1, page 108
• E-mail the .m script to the instructor.

Assignment 16: Matlab Functions II (Exercises in Kaplan)

• Exercise 6.2 on pages 128-9.
  • Organize the results into a single text file that contains the definitions for all required functions, and that includes the Matlab output to demonstrate those things required by the assignment.
• Exercise 6.5 on page 129.
• Exercises 8.5, and 8.6, on page 178.
• E-mail the functions to the instructor. DO NOT send individual .m files! You should combine all answers into a single e-mail message or text file.

Exam Prep Examples

For exam prep, we worked two problems, a matrix problem and a string problem.

The matrix problem: We needed a function to multiply each element of a vector by a constant, and sum the result. The arguments included the vector and the constant (and for C, the length of the vector).

The string problem: We needed a function that took an input string and split it into 2 output strings. In Matlab, the function took a string and an index as arguments and returned two results. In C, the function took 2 strings as arguments, and an index, and returned no results (void); instead it shortened the input string and copied the split part to a second string.
