Hi im a student and i have an assignment to do, and i seem to be a bit stuck.
I have a list of numbers which i have read from a file i need them in a list like so,
25.00
43.00
15.00
456.00
but i am getting,
25.00
43.00
25.00
456.00
I have used %4.2f to display the numbers.
Please help, thank you Ganonshin. Bye.

Well from the looks of it, you're getting exactly what you want.You should learn how to use formatting tags here. That aside, try using the - instead.
%-4.2

Hope is the first step on the road to disappointment.
Hi again Quzah.
I have just tried using the - sign, it didnt do anything to the way my figures are displayed.
The figures should be displayed justified from the right, so there should be a straight line down the right hand side of the figures, which there isn't.
Heeeelllllpppp!!!!!!
Ganonshin.
Why don't you just use a bunch of tabs?
The world is waiting. I must leave you now.
Hi Shadow.
If i use tabs i cannot put my figures where i want to, can i??
Can you expand on your theory?
Ganonshin.

To get the results you were originaly trying for, and also make what you were already using work like you expected, with those figures you need to use at least %6.2f. The number before the dot(width specifier)means how many total characters to print including the decimal. Adding a zero to the begining of the width specifier pads the numbers out with zeros instead of blanks - ie %07.2f will give you:
0025.00
0043.00
0015.00
0456.00
There are other and probably better ways to do this but whatever.
It was a bit hackish, but:
Code:#include <stdio.h> void right( char * text ); int main() { right(" 25.00\n"); right(" 43.00\n"); right(" 25.00\n"); right("456.00\n"); return 0; } void right( char * text ) { printf("\t\t\t\t\t\t\t\t\t%s", text); }
The world is waiting. I must leave you now.
I haven't tested this, but if you're using printf, can't you use the width argument combined with an align right?

Thanks Shadow, proof you should always test it

Demonographic rhinology is not the only possible outcome, but why take the chance
Do you have that link right?
The world is waiting. I must leave you now.
The proof
[code]
int main(void)
{
char num1[]={"425.00"};
char num2[]={"50.00"};
float num3=13;
double num4=15.2;
printf ("Number 1 %10s \n",num1);
printf ("Number 2 %10s \n",num2,10);
printf ("Number 2 %10.2f \n",num3,10);
printf ("Number 2 %10.2f \n",num4,10);
return 0;
}
[code]
Demonographic rhinology is not the only possible outcome, but why take the chance
Or even
Code:#include <stdio.h> int main(void) { float f; for (f = 1; f < 100002; f *= 10) { printf("Number is now %10.2f \n", f); } return 0; }
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
Thanks to all that have responded, below is part of the output.
This is what I want,
/* 4 15 20 1 7.0 105.00 11.0 165.00 */
/* 4 7 10 2 9.0 90.00 11.0 110.00 */
This is what I get
/* 4 15 20 1 7.0 105.00 11.0 165.00 */
/* 4 7 10 2 9.0 90.00 11.0 110.00 */
I have justified all the specifiers exept the ones that will only print out one number, it seems to work alright with the 15 as you can see, the problem is with the 105.00.
Ive tried everything I can think of, please help, Ganonshin.

Use code tags that way you won't loose the formating in your post.
And try making your width wider in printf() eg
>print("%10.2f\n", flt);
When all else fails, read the instructions.

Hammer i have used tags but the format still aint right strange i must be doing something wrong.
Also i have used what you wrote, but basicly the justification i am using works for the 15 (in by previous thread), but not for the 105.00. It prints like
105.00
90.00
instead of
105.00
X90.00 /* minus the X of course*/
Is that a bit clearer??
Help please anyone, cheers from Ganonshin.
Post the code that is doing the printing. Code tags are done like in my signature....
