Cant Figure Out File I/O Error!

Objective of this program is to read binary data from a file and print it.

Code:

---

#include <stdio.h>


void readFile(void);


int main(){
    readFile();
    return 0;
}


void readFile(void){
    FILE *fp;
    char ch;
    if((fp = fopen("newfile","rb"))==NULL){
        printf("Error reading.\n");
        return;
    }
    while(!feof(fp)){
        if(fread(&ch, sizeof ch, 1, fp)!=1){
            printf("Error.\n");
            return;
        }
        putchar(ch);
    }
    fclose(fp);
}

But When I Run This Code First It Print "Error." Then Rest Of The File.Say In My File I Have "I AM HUMAN", It Prints "Error. HUMAN"!!
I Cant Figure Out Whats Wrong In The readFile() Function.It seems right to me.

Quote:

---

n My File I Have "I AM HUMAN"

Why are you opening the file in binary mode instead of text mode and why are you using fread() instead of fgets()? The description of your file sounds like a text file. How did you write this file? Normally with binary files you must first write the file with unformatted output functions like fwrite() before you try to read it.

Also what operating system are you using?

First of all i have used binary mood cause if i used text mood functions like fgets() or fscanf(), i have to use array to catch string from file but i want to make my program dynamic so that it doesn,t depend on file size as array does.I have also assume that i didn,t know file size.if i used array i have to knew that.Another reason for that is its better using binarry mood than text mood as conversion happens when using text mode function.Yes, In description i have used only text as example but its not constant that i will only use text i want to use any type of data.

Yes, I have written file using fwrite();

I am using windows.

Thanks :)

I can't reproduce that "Error." is printed before the content of the file. If I run your program it is printed after the content. Reason: FAQ > Why it's bad to use feof() to control a loop - Cprogramming.com

Thanks.
