Thread: Homework Question...

Ooooooooh, I see what you mean now. Sorry, you can't portably fix it. Input in C is line based, which means you need to hit enter for any input to be sent to the program. Because of this that newline will be printed before you can do anything about it. Try this and see if you can tolerate it:

Code:

#include <stdio.h>

int main(void)
{
  int pair1, pair2, pair3, pair4, pair5, total, vchar;

  scanf("%2d%2d%2d%2d%2d", &pair1, &pair2, &pair3, &pair4, &pair5);

  total=(pair1+pair2+pair3+pair4+pair5);
  vchar=total%26+65;

  printf("Input Code	10 Digit Sum	Numeric		Validated\n");
  printf("		    Code Value	    Code Value  Code\n\n");
  printf("%2d%2d%2d%2d%2d", pair1, pair2, pair3, pair4, pair5);
  printf("%8d%10d%10d%12d%2d%2d%2d%2d%c\n",total,vchar-65,pair1,pair2,pair3,pair4,pair5,vchar);	

  getchar();

  return 0;
}

>Is there any way of doing that?
...Yes, but I don't recommend it. And it pains me to know in my heart that you're going to rejoice when you see it work like you want and that you're going to use it. And it pains me even more to know that you'll continue to use it when you don't need to despite portable options:

Code:

#include <stdio.h>
#include <conio.h>

int main(void)
{
  int pair1, pair2, pair3, pair4, pair5, total, vchar;

  printf("Input Code	10 Digit Sum	Numeric		Validated\n");
  printf("		    Code Value	    Code Value  Code\n\n");

  cscanf("%2d%2d%2d%2d%2d", &pair1, &pair2, &pair3, &pair4, &pair5);

  total=(pair1+pair2+pair3+pair4+pair5);
  vchar=total%26+65;

  printf("%8d%10d%10d%12d%2d%2d%2d%2d%c\n",total,vchar-65,pair1,pair2,pair3,pair4,pair5,vchar);	

  getchar();

  return 0;
}

>How about in C++ if C can't handle it.
C++ would suffer the same problem, and have the same non-portable solution.

>Why does it pain you?
I'm very anal about writing code that conforms to the C standard. Introducing a non-standard header and function for some frivolous formatting chafes.

>And what does more "portable options" mean?
It generally means compromising nifty features for the ability to compile your code on any machine with a C compiler and have it work properly.

It is my sworn duity (because I swear a lot), to damn you for your post! And so I shall!

Code:

void main(void)

Go read this FAQ entry now!

Code:

fflush(stdin);

When you're finished, go read this FAQ entry!

Heed my words, neophyte, lest you be haunted by the ghosts of coders past, and posters present! (Mainly posters present, like myself!)

Quzah.

> And what does more "portable options" mean?
It also means you don't have to learn (and relearn and relearn and ....) a whole bunch of stuff each time you upgrade or change your compiler.
