newbie question

[abhiii]

Hi,
I'm trying to write a program which just reads from a file and prints the characters on the screen, plz take a look at the code and tell me whats wrong

# include <stdio.h>
# include <stdlib.h>
# include <fcntl.h>

main(int argc, char *argv[])
{
        int i,j;
        char c;
        FILE *fp;

        if(argc < 2)
          fprintf(stderr, "usage a.out <filename>\n");
        fp = fopen(*++argv, O_RDONLY);
        if(fp == NULL)
        {
                fprintf(stderr, "File cannot be opened\n");
                exit(1);
        }
        else
        {
                while ((j = read(fp, &c, 1)) != 1)
                {
                //      j = read(fp, &c, 1);
                        if(j <= 0)
                           break;
                        else
                           putchar(c);
                }
                fclose(fp);
        }
}

while ((j = read(fp, &c, 1)) != 1)

That statement is never going to be true (unless there's nothing in the file). Think about it and read the manual for the read function.
