Aligning/justification problem

[JFonseka]

Hi, I'm a beginner programmer, I pretty much did the exercise I was supposed to do, except I don't know how to justify one set of numbers specifically

This is the end result:

k sum
--------
1 1
2 3
3 6
4 10
5 15
6 21
7 28
8 36
9 45
10 55
11 66

as you can see as it continues like this, due to 10 and the other 2 digit numbers, the numbers in the sum get shifted, i want them to stay in a justified order, how do I do that?

here is the code:

//SUMK - prints the sum of the numbers from 1 to k, for all values of k between 1 and 20.

#include <stdio.h>

int main (int argc, char **argv) {
  
  int sum = 0;
  int k = 1;
  
  printf ("k      sum\n");
  printf ("----------\n");
  
  while (k < 21) {
    
    sum = sum + k;
    printf ("&#37;d", k);
    printf ("%9d", sum);
    printf ("\n");
  k++;
  }  
  return(0);
}

These posts start automatically justifying when I don't want it to!!! Here is what the output looks like:

Use %9d or some other number for the first printf() as well.

If you want the numbers to be left-aligned, use %-9d.

Also, %09d fills the extra areas with zeros instead of spaces.

[edit] So how do you like ConTEXT? . . . [/edit]

Well you've already used 9d for one set of formatting, explore other numbers for the other printf

BTW
printf( "%d%9d\n", k, sum );
would also work.


Hint: try "%-4d"

Indeed it does, never noticed that, should have thought to try it, thanks! Context is fine...lol, why?

-4d works good with 6d on the other one, thanks!!

I see you're using Vista, and I'm trying to figure out which of my editors (ConTEXT is one of them) will work with Vista . . . anyway, it's not that important. I'll find out soon enough.

Yea context v 0.98.3. I compile using cygwin though

[JFonseka]

In fact, i tried a bunch of other editors that could compile as well with vista and most failed or created errors in the output which i could not understand, so I decided to use context for editing and cygwin for compiling and execution and it works really well, it automatically justifies the code, so I like it.

I see. I installed Dev-C++ on Vista but it didn't work. (The GCC port, that is.) GCC only worked when run from bin/. I tried meddling with its library paths, include paths, you name it, but still no luck.

Anyway, I "fixed" it with a program which cds to the right directory and calls GCC from there. I intend to install Cygwin on the computer sooner or later, so we'll see how that works.

Yes, exactly, so you know what I mean. I can send you the program I used to patch Dev-C++ if you like. It's not on this computer though.

I'll have to search around to see if anyone else has encountered/fixed this problem. [/edit]

[edit=2] I don't think it's a simple path problem, though it could be. I didn't debug it very extensively. [/edit]

Lol I did not understand much of those parameters you can put into the compiler so I left it alone. I guess they will release a vista compatible version later, vista is probably just recognizing it's gcc calling command as a potential security threat and ending it early, I'm just speculating, I'm a complete noob and probably wrong.
But yea, Vista isn't the most flexible when it comes to development for home users at the moment.
