Thread: Print everything after Ctr+D

I want to create a small program that will get text with getchar() and print all the text added after the Ctr+D button
Here is my code:

Code:

#include <stdio.h>

main()
{
int c;
while(c=getchar()) != EOF)
if(c=EOF)
{
putchar(c);
}

}

The problem is it doesn't working any ideas?

Code:

#include <stdio.h>

int main(void)
{
    int c;

    while ( (c=getchar()) != EOF )
    {
        putchar(c);
    }
}

Code:

#include <stdio.h>

#define B_SIZE 256

int
main (void)
{
  char s[B_SIZE];  int i = 0, ch;

  while ((ch = getchar()) && i < B_SIZE-1)
  {
    if (ch == EOF)
      break;
    s[i++] = ch;
  }
  s[i] = '\0';

  printf ("\n\n\"%s\"\n\n", s);
  return 0;
}

In a strange way, noone of these program works?

Please be specific. In what way doesn't mine work?

Why would there be any text after the ctrl+D? You hit that to end input. The code looks for it and stops receiving input. If you want to keep receiving input you need to write code that ignores EOF, not that checks for it and stops when it gets it. You'll need some other way to trigger it to stop trying to get input though. Why do you want this anyway? The whole point of EOF is to say that there's nothing else after it.

I assumed the OP wanted the text to be displayed after input had been closed with EOF -- ie, instead of being echoed one char at a time as input is collected with getchar() ... that way it makes sense.

The only advantage to doing it this way rather than using the usual line-oriented methods is that input can include \n's ...

Code:

#include <stdio.h>
main()
{
char c;
while((c=getchar()) != EOF)
;
if(c==(char)(-1))
{
putchar('d');
}

}

check this out....its working....

> if(c=EOF)
1. It should be ==, not =
2. It will never be true, the while loop test makes sure of that.

Code:

while ( (c=getchar()) != EOF ) {
  // do stuff upto first EOF
}
// ctrl-D gets you here, and more calls to getchar() will return EOF unless....
clearerr( stdin );
while ( (c=getchar()) != EOF ) {
  // do more stuff upto second EOF
}

kiranck007 not it isn't what I wanted to do

I want a program that will let you write:
for example
asdjsajfhsdjhfjsdhfjksdhjfkhsdkjhfsdhf
sdfsdhfjksdhjfkhsdjkahf
asdfdsfsdf sdksjfsdfCOOL
/*and after clicking Ctrl+D it will post to you everything you have writed*/
asdjsajfhsdjhfjsdhfjksdhjfkhsdkjhfsdhf
sdfsdhfjksdhjfkhsdjkahf
asdfdsfsdf sdksjfsdfCOOL
That's all!

Code:

#include <stdio.h>

#define B_SIZE 256

int
main (void)
{
          char s[B_SIZE];  int i = 0, ch;

            while ((ch = getchar()) && i < B_SIZE-1)
                      {
                                  if (ch == EOF)
                                                break;
                                      s[i++] = ch;
                                        }
              s[i] = '\0';

                printf ("\n\n\"%s\"\n\n", s);
                  return 0;
}

I found this code but it is too complicated for me? Anyone know any better way?

What on earth did you do to my formatting?

Anyway, try this -- it does the same thing but it's simpler.

Code:

#include <stdio.h>

int
main (void)
{
  char s[4096];  int i = 0, ch;

  while ((ch = getchar()) != EOF)
    s[i++] = ch;
  s[i] = '\0';

  printf ("\n\n%s\n\n", s);
  return 0;
}
