    I'd advise purchasing/borrowing "The C Programming Language" (Kernighan and Ritchie) otherwise known as the K&R book. It covers I/O for files as well as low-level access in Unix and is *the* C reference book.

    this program will read a file and count how many characters, spaces and newlines are present in a file

    [quote]

    #include "stdio.h"

    void main()
    {
    FILE *fp;
    char ch;
    int nol=0, not=0,nos=0,noc=0;

    fp=fopen("Test","r");

    while(1)
    {
    ch=fgetc(fp);

    if(ch==EOF)
    break;
    noc++;

    if(ch=="")
    nob++;

    if(ch='\n')
    nol++;

    if(ch=='\t')
    not++;

    }

    fclose(fp);

    printf("\nNumber of characters=%d",noc);
    printf("\nNumber of blanks=%d",noc);
    printf("\nNumber of tabs=%d",noc);
    printf("\nNumber of lines=%d",noc);
    }[\quote]


    haven't compiled but it should work let me know if it dosen't or u don't understand anything

    before a file could be read or written it must be opened. opening a file establishes a link between the program and the operationg system. the link between our prog and the OS is a structure called FILE which has been defined in the header "stdio.h". we request the OS to open a file and what we get back is a pointer to the structure FILE. that is why we make the following dec.


    FILE *fp;

    i can understand the rest of the code except
    fp=fopen("Test","r");
    fp is the file pointer what does fopen() do
