Text Formatting: alignment FILE
hi guys..
Must to write a program that takes 2 parameters from the command line:
A) the name of a text file, and
B) N the number of characters per line.
The program should open the data file, reads the text, and the printed
TAKES the main output aligned in rows of length N.
how i will do that?
THANKS
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
thanks man.. but i know this part of the problem..Originally Posted by Salem
how i can do the others?
How about you show us all the parts you CAN do (reading command line arguments, opening files, reading words, counting lengths of words or whatever).
Then we can help you with the issue which is really bugging you, as opposed to you replying "yeah, I knew that already".
Instead of this guessing game which I'm already bored of.

salem please dont reply again in my thread..
guys(expect salem) my main problem is how to do the aligment.. maybe some standar fanctions?
Look up fopen(), fgets(), fclose(). How do you mean align the rows? Right-align each word to a right margin for example?
i mean middle margin...
Perhaps it's time you read this

Like I'm going to pay any attention to that kind of demand.

So you mean you want to align words to be centered? If the width is N (number of characters per line), then you can print out each word by preceding them with (N - strlen(word)) / 2 spaces.
Consider the example of using example.txt file that contains the text:
As you know, I’m quite keen of comic books, especially the
ones about superheroes. I find the whole mythology surrounding
superheroes fascinating. Take my favorite superhero; Superman, not a
great comic book, not particularly well-drawn, but the mythology;
the mythology is not only great, it’s unique.
Then the command ./ask example.txt 60 should produce the output:

superhero; Superman, not a great comic book, not

not only great, it’s unique.
Look up the string functions from string.h and print from stdio.h.
strcat - C++ Reference
sprintf - C++ Reference
You are very likely to need strcat (or maybe strncat) but you might be able to use sprintf (or maybe snprintf) instead.
The other functions will depend on your design.
The above is needed for one way of solving the problem.
The other obvious way to to use fgetc and fputc functions.

and? how this function will help me? i think you havent undrestard what i want to do.. the user will gives a file..
I understand perfectly, you want someone to hand you code instead of looking at links and learning to program.
You are now on my ignore list, goodbye.

Oh OK. You want to read the file word for word and try to place as many words in one line so that the line length is <= 60, output each line.
yes my friend.. the 60<= its example the user willgives the number of words in line..
