The following guidelines are expected for all homework submissions:
all over the mapon my computer or printer. USE SPACES INSTEAD. You can set up almost every modern text editor to insert spaces whenever you press the TAB key, or you can simply pound the spacebar.
pair programmingwhich is part of the Extreme Programming [Agile] software development method. Feel free to collaborate in your pairs as much as you want, doing the entire assignment together. Only submit ONE copy for the both of you.
Cprogram,
dec2bin.c
to convert a base-10 number to its 32-bit binary
value equivalent. You may take the base-10 number in from the command line, or you may prompt the
user for the number and read in her response [your option]. Your output must be a string of
32 binary digits which correspond to the base-10 value. For example, running the program with
dec2bin 65535
[or just dec2bin
if asking the user] should produce the
output string 00000000000000001111111111111111
. Use unsigned integers and error check
the entry [as you always should].
Cprogram from problem #1 to to make the program
dec2hex.c
which
will output the 32-bit hexidecimal value equivalent in 8-digit format with a leading 0x. For this modification, you must also handle an optional command line argument which indicates the number of bits that the output hex value will represent, either
32or
64. If there are no arguments present on the command line, you must ask the user for the number to convert and default to the number of bits in the representation. For example, running the program with
dec2hex 65535 32
[or just dec2hex 32
if asking the user for the value]
should produce the output string 0x0000FFFF
. Running the program with input
dec2hex 65535 64
[or just dec2hex 64]
will result in the output of
0x000000000000FFFF
. Use unsigned integers. Remember "32" will produce 8-digits and
"64" will produce 16 digits. Both outputs must be prefixed with "0x".
Cprogram
timesTables.c
to output the times tables from 2 to N
,
where N
is a user-defined number taken from the command line [not an
option for this one]. Output the values in a nice table, using a format specifier that will allow
for enough space for the results to be neatly aligned in columns. You may need to adapt the format
to allow for increasingly large results. For example, timesTables 5
should produce an
output as follows:
You will need to research the output format specifiers for1 2 3 4 5 2 4 6 8 10 3 6 9 12 15 4 8 12 16 20 5 10 15 20 25
printf()
.
Cprogram
holdit.c
that times you as you hold your breath. The program
must put out a short message that has instructions on what to do, which should read something
like,
You will need to research the way the time functions work inThis program will time how long you can hold your breath. Take a deep breath, then press the 'Enter' key. When you absolutely have to exhale, press the enter key again. The duration will be displayed in minutes and seconds.
C.
Cprogram
wordcount.c
that counts the number of words in a file of
text. Your program must take a file name as a command line argument. As you read the file's
contents, keep a count of the number of words which are separated by whitespace. [Research what is meant by "whitespace" in the
Cenvironment.] When the file has been completely read, close the file and write out the number of words to the terminal. Be sure you handle any error conditions like files that don't exist or errors while reading the file. You must also be able to handle files that are in different directories from where your program resides.
