It's so common to hear people start sentences with "I am"
(as opposed to
René Descartes, who is famous for ending a sentence like that).
The Department of Sociology
might be interested in a study of the qualities that people believe they
possess.
With the careful use of
hidden microphones
and IBM's
Watson Speech to Text software, it has been possible to obtain
transcripts of several conversations.
Let's see what people think of themselves ...
Write a program that:
- Opens a file called MyQualities.txt for writing.
- Repeatedly ...
- Reads a sentence from the keyboard (using fgets).
- Checks if the sentences starts with "I am " (using strstr)
- If it does, then extracts the substring starting at the 5th character,
i.e., the substring containing the quality the person believes they
possess. (using strncpy).
- Concatenates the substring onto a growing string containing all such
qualities, with a comma separator (using strncat - the growing
string has a maximal length of 1024 characters).
- Appends the substring to the MyQualities.txt file.
- Stops looping when a string containing just a "." is entered (check
using strcmp).
- Closes the file
- Outputs the grown string of qualities to the screen.
- Opens the MyQualities.txt file for reading
- Reads and echo the qualities from the file
- Closes and deletes the file
Here's what a sample run should look like (with the keyboard input shown in
italics) ...
Please enter sentences, . to end.
