Write a program that performs character processing on 10 characters read in
from a file, and writes the results to output files. Do NOT use loops or arrays
to solve this problem.
NOTE: You may NOT use the standard library functions found in .
Your program should define the following functions:
(2 pts) FILE * open_input_file (void) — Opens "input.dat" for reading.
(2 pts) char read_character (FILE *infile) — Reads one character from the
input file.
(2 pts) int determine_ascii_value (char character) — Returns the ASCII
value of the character passed into the function.
(4 pts) int is_line (char character) — Determines if the character is a
newline, if the character is a newline a 1 is returned otherwise a 0 is returned.
Make sure that you #define two constants NEWLINE and NOT_NEWLINE as 1
and 0, respectively. Return the #defined constant.
(4 pts) int number_lines (char character, int current_number_lines) —
Determines if the character passed into the function indicates the end of a
line (use is_line ( )),
if so the function adds 1 to the current_number_lines and returns the
value; otherwise it returns the current_number_lines without any modification.
(4 pts) int is_vowel (char character) — Determines if the character is a
vowel (note: the character may be lower or upper case), if the character is a
vowel a 2 is returned otherwise a 0 is returned.
Make sure that you #define two constants VOWEL and NOT_VOWEL as 2 and
0, respectively. Return the #defined constant.
(4 pts) int number_vowels (char character, int current_number_vowels) —
Determines if the character passed into the function is a vowel (use is_vowel (
)),
if so the function adds 1 to the current_number_vowels and returns the
value; otherwise it returns the current_number_vowels without any
modification.
(4 pts) int is_digit (char character) — Determines if the character is a digit
(i.e. '0' - '9'), if the character is a digit a 3 is returned otherwise a 0 is
returned.
Make sure that you #define two constants DIGIT and NOT_DIGIT as 3 and 0,
respectively. Return the #defined constant.
(4 pts) int number_digits (char character, int current_number_digits) —
Determines if the character passed into the function is a digit (use is_digit ( )),
if so the function adds 1 to the current_number_digits and returns the
value; otherwise it returns the current_number_digits without any
modification.
(4 pts) int is_alpha (char character) — Determines if the character is an
alpha character (i.e. 'a' - 'z', 'A' - 'Z'), if the character is an alpha character a 4
is returned otherwise a 0 is returned.
Make sure that you #define two constants ALPHA and NOT_ALPHA as 4 and
0, respectively. Return the #defined constant.
(4 pts) int number_alphas (char character, int current_number_alphas) —
Determines if the character passed into the function is an alpha character (use
is_alpha ( )),
if so the function adds 1 to the current_number_alphas and returns the
value; otherwise it returns the current_number_alphas without any
modification.
(4 pts) int is_lower (char character) - Determines if the character is a
lowercase character, if the character is a lowercase character a 5 is returned
otherwise a 0 is returned.
Make sure that you #define two constants LOWER and NOT_LOWER as 5 and
0, respectively. Return the #defined constant.
(4 pts) int number_lowers (char character, int current_number_lowers) —
Determines if the character passed into the function is a lowercase character
(use is_lower ( )),
if so the function adds 1 to the current_number_lowers and returns the
value; otherwise it returns the current_number_lowers without any
modification.
(4 pts) int is_upper (char character) - Determines if the character is an
uppercase character, if the character is an uppercase character a 6 is returned
otherwise a 0 is returned.
Make sure that you #define two constants UPPER and NOT_UPPER as 6 and
0, respectively. Return the #defined constant.
(4 pts) int number_uppers (char character, int current_number_uppers) —
Determines if the character passed into the function is a uppercase character
(use is_upper ( )),
if so the function adds 1 to the current_number_uppers and returns the
value; otherwise it returns the current_number_uppers without any
modification.
(4 pts) int is_space (char character) - Determines if the character is a
whitespace character (i.e. space ' ', form feed '\f', new-line '\n', carriage return
'\r', horizontal tab '\t', and vertical tab '\v'),
if the character is a whitespace character a 7 is returned otherwise a 0 is
returned. Make sure that you #define two constants WHITESPACE and
NOT_WHITESPACE as 7 and 0, respectively.
Return the #defined constant.
(4 pts) int number_spaces (char character, int current_number_spaces) —
Determines if the character passed into the function is a space character (use
is_space ( )),
if so the function adds 1 to the current_number_spaces and returns the
value; otherwise it returns the current_number_spaces without any
modification.
(4 pts) int is_alnum (char character) - Determines if the character is an
alpha or digit character, if the character is an alpha or digit character a 8 is
returned otherwise a 0 is returned.
Make sure that you #define two constants ALNUM and NOT_ALNUM as 8 and
0, respectively. Return the #defined constant.
(4 pts) int number_alnums (char character, int current_number_alnums) —
Determines if the character passed into the function is an alphanumeric
character (use is_alnum ( )),
if so the function adds 1 to the current_number_alnums and returns the
value; otherwise it returns the current_number_alnums without any
modification.
(4 pts) int is_punct (char character) - Determines if the character is a
punctuation character (i.e. '.', '!', ',', etc.) if the character is a punctuation
character an 9 is returned otherwise a 0 is returned.
Make sure that you #define two constants PUNCT and NOT_PUNCT as 9 and
0, respectively. Return the #defined constant.
(4 pts) int number_puncts (char character, int current_number_puncts) —
Determines if the character passed into the function is a punctuation character
(use is_punct ( )),
if so the function adds 1 to the current_number_puncts and returns the
value; otherwise it returns the current_number_puncts without any
modification.
(3 pts) void print_int (FILE *outfile, int number) — Prints an integer to an
output file.
(3 pts) void print_stats (FILE *outfile, char header[ ], int number) — Prints
a line like the following:
Number Vowels: 45
where "Number of vowels" is the string represented by the variable
header and 45 is represented by number.
(10 pts) A main function that does the following:
Opens an input file input.dat for reading;
Opens an output file output_stats.dat for writing all data generated by
print_stats ( );
Opens an output file output_ascii.dat for writing all ascii values of each
character;
Checks to see if the files were opened successfully
Reads one character at a time from the input file (input.dat), until all 10
characters have been read; For each character that is read in, its
corresponding ASCII value should be printed to the output file,
output_ascii.dat; Hint: use the print_int ( ) function to print the ASCII
values;
Prints the number of lines in the file to output_stats.dat;
Prints the number of vowels in the file to output_stats.dat;
Prints the number of digits in the file to output_stats.dat;
Prints the number of alpha characters in the file to output_stats.dat;
Prints the number of lowercase characters in the file to output_stats.dat;
Prints the number of uppercase characters in the file to output_stats.dat;
Prints the number of space characters in the file to output_stats.dat;
Prints the number of alphanumeric characters in the file to
output_stats.dat;
Prints the number of punctuation characters in the file to
output_stats.dat;
Closes all opened files;
Sample Execution:
The following sample session demonstrates how your program should work,
although your program is only required to read in 10 characters.
Assuming input.dat stores the following characters:

V. Submitting Assignments:
1.
Using Blackboard Learn https://learn.wsu.edu/webapps/login/ submit
your assignment to your TA through the link ending with “-LAB”. Under
the "Content" link navigate to the "Programming Assignment Submissions"
folder and upload your solutions to the appropriate “Assignment” space.
You must upload your solutions as _pa3.zip by the due
date and time.
Your .zip file should contain your one header file (a .h file), two C
source files (which must be .c files), and project workspace. Delete the
debug folders before you zip the project folder.
3. Your project must build properly. The most points an assignment can
receive if it does not build properly is 65 out of 100.
