confused how to begin this program

Dec 10th, 2004

i am taking a cpsc 140 class and i'm a little confused how to begin my assignment. Write a C++ program that reads in an unknown number of characters from the a text file, count the number of words, and print each word in reverse to the screen.
Words are delimited by blanks, tabs, newlines and the end of file. Note that mulitple whitespace characters should only count one word. Hint: You can use the get method to enter whitespace . i dont recall what the get method is. if anyone can start me out i would be greatly appreciated. thanks

int fgetc(FILE* stream);
Returns next character from (input) stream stream, or EOF on end-of-file or error.

Just a little help ...
[php]// pulls the words out of a text stream
string get_word(istream& in)
{
char ch;
string s;

while(in.get(ch))
{
// these characters separate the words
if (ch == ' ' || ch == ',' || ch == '.' || ch == '\n' || ch == '\t')
break;
s.push_back(ch); // build the word
}
return s;
}
[/php]

May 'the Google' be with you!

steps:
1) order a large amount of coffee
2) order some pizzas
3) kickstart your brain
4) start thinking how you would solve it
5) write down your solution in words on a piece of paper
6) translate that into a flowchart and/or other diagrams
7) translate that into a functional model of your application
8) translate that into code
9) test and fix until working

thanks for all the help..the only thing i cant figure out now is how to put the actual text file in. the text is :

this is a file containing lots of
words with whitespace such as tabs and
endoflines and blanks but no
punctuation
you should be counting the
words and reversing each word before
echoing this tothescreen at the end
print the number of words in the file

is there a way for me to put this in without actually putting all this text in my code?

Sure, and that's exactly how you should do it:

Create a textfile on disk.
Read in the file in your program. C(++) has full facilities for reading and writing any kind of file built right into the core language.

Select the text in your editor and save it as test.txt then read it into your program as a text file. You can separate the text into words with strtok(), setting the appropriate delimiters. It's up to your genius to spell each word in reverse.
