Due: Wednesday, September 20, 2016
The Written Problems section is
due in class on the due date.
The Programming Problems section
is due to me by e-mail no later than
11:59 pm - see the Deliverables
This assignment is worth 34 points.
King: Skim through Chapters 7-9 (arrays and functions) to make sure you
have the idea. Then
study Chapters 11 and 13 in
Problems (18 points).
- (2+2 points) King, page 121:
Exercises 2 and 8
- (2+3 points) King, page 157:
Exercises 4 and 13
- (4 points) King, page 255:
Exercise 2 but omit part (e)
points) King, page 255: Exercise 3. Assume the formal
parameters given are declared correctly.
- (2 points) We said in class
that C does not check the bounds of arrays, so the programmer has to
remember to do that. The function getline1
(attached) reads a line of input and stores it in the array str.
This function is considered safe
because it stops reading characters when the array is full. Briefly
explain how the function does this, showing the line of code where the
Programs (16 points).
- (4 points) Use printf
scanf to write a
program that accepts as input a date of the form
mm/dd/yyyy. Use three
integers to hold each part of the date. Now display it in the ISO
Standard Format for dates: yyyy-mm-dd.
Ensure that the output date uses exactly 2 characters to display the
month and day. An example run (user input is underlined):
Enter a date (mm/dd/yyyy): 2/3/2011
You entered the date 2011-02-03
- (6 points) Write a program
which prompts the user for a number of two-dimensional points to
enter, and then in a loop, prompt for the label and X and Y
coordinates of that number of points. For example, if the user enters
6 as the number of points, your input loop will execute six times. The
points will go into an array of struct
After entering the points, your program will compute the distance
between each pair of points. Output the two closest points, the two
points that are farthest apart, along with their distances. Make
use of point.h and point.c from HW 0.
- (6 points) King, page 122:
Programming Project 1. Use an array.
- Combine your source code and
screenshots only into a zip file. No
executable or objects files, please!
your zip file to the instructor as
an attachment for testing
- Turn in a printout
of the source code in class or in the box outside my office
