To output the contents of a text file

[jhamb]

Hye,

I wanted to get a help to display the contents of a text file.
It contains 1024 bits but output shows just 300 bits.
There may be some problem. The program should start reading the file from beginning, but its counting only last 300 bits.

Here's my code :

#include "iostream.h"
#include "stdafx.h"
#include "conio.h"
#include "string.h"
 
int main(int argc, char* argv[])
{
 
     char ch;
    char fname[]="\0";
    strcpy(fname,"D:\code.txt");
    FILE *fp;
    fp = fopen(fname,"r");
 
    while(!(fread(&ch,1,1,fp)==0))
    {
        cout<<ch;    
    }    
 
    fclose(fp); 
    getch();
    return 0;
}
 

Any one can help..!
Thanks.

Is this a C or C++ code?
Also what you mean by 1024 bits..
In a file every character is a byte.
Can you attach the ip file also

Its a CPP file..
Code.txt file contains digits 1 or -1.
Here we use -1 in place of 0.
They are 1024 in total.

In a txt file the minus sign is a character.so when you say 1024 -1's and zeros you need to account for those. also depending upon the whay its written your loop to display the code may count a line break as a character.
So taking this into account
300 x 1
150 x -
300 x \n newline
300 x \r carriage return

1050 - give or take a few...

this is why you are only getting about 300 of your characters.
because each character is treated individualy. Hope this helps....

If this is C++ code, then you should be using <iostream> and not <iostream.h>.

iostream.h is the pre-ANS C++ that was used prior to 1998 so it's 10 years out of date.

Also, the C-string library is deprecated in C++. You should be using the C++ string object and not C-strings that are kept in arrays.

Also, you should be using file stream objects and not eh C FILE* stuff.
