    how do i read an external file

    I looked it up in the c book I have but it wasn't very clear. I also tried to search the site but there were too many specific examples.

    I was wondering how I read a text file and then do something with it in a program. For example, look for a specific word in a text file (with a list of words).

    I think this is a simple problem but I couldn't really find a simple answer so I had to post it here. I hope there's someone who can help.

    Thanks.

    To read you can use fscanf, fread, fgets, fgetc, getc ...
    To write you can use fprintf, fwrite, fputs, fputc...

    Try searching the web for these functions to see how they work.

    >For example, look for a specific word in a text file (with a list of words).
    Try do this without using files, and then translate the input/output functions so that they can read from/print to a file.

    checkout cplusplus.com

    from their site
    Code:
    /* fopen example */
    #include <stdio.h>
    int main ()
    {
      FILE * pFile;
      pFile = fopen ("myfile.txt","wt");
      if (pFile!=NULL)
      {
        fputs ("fopen example",pFile);
        fclose (pFile);
      }
      return 0;
    }

    Use this:

    C_Ref_Card.pdf

    It has all the info on functions and basic descriptions. For examples on use do a search on this forum. I did a string program for someone not to long ago that should provide a decent template for using them.

    That card is like the ULTIMATE refrence, I think.

    Thanks mart_man00 and Lynux-Penguin. The C ref card was awsome.
