not printing the last number

1 2 3 4

file "text1.txt" contain the above data

Code:

---

#include<stdio.h>
void main()
 {
        FILE *fp;
        int i;
        fp=fopen("text1.txt","r");
        while((i=getw(fp))!=EOF)
        putw(i,stdout);
 }

---

Output:
1 2 3

But it should be 1 2 3 4..Where is 4?
I am not getting the answer..Please help me out.

Is there a newline at the end of the line?

Perhaps you need fflush(stdout); if there isn't.

Then again, perhaps you're using that old fossil known as TurboC.

That data is in a file. I am using TurboC 4.5.
I have already used that fflush(stdout);

So why are you using getw/putw (wide chars) instead of getc/putc ?

Thanks. Its working. But if I want to do any arithmetic operation will getc work? I think not.

Depends on what you mean by "arithmetic operation". If '1' and '2' are read in, adding them will not yield the character '3'. However, since they are integral values, they can be added.

You've definitely got the wrong idea, if you thought that reading "1 2 3 4" using getw would have given you integers 1 2 3 4.

getw reads 2 bytes WITHOUT any interpretation. So the first time around, you would have an int containing 0x3120 (or 0x2031), where 0x31 is the ASCII value for '1' and 0x20 is the ASCII character for a space.

Look at something like fscanf, if you want to convert character '1' into numeric 1.
