How to right justify a column

[jwatts]

Hello group,

I am feeling pretty good about this program. I am just learning and
am trying to get the basics down. I would like to ask if someone
could tell me how to right justify the BALANCE column in my program's
output.

===============
Here is my code:
===============

#include <stdio.h>

int main (void)
{
int i;
int accountNumber[10];
char lastName[10][30];
float accountBalance[10];

printf("Enter account number, last name, and balance.\n");
printf("Enter -999 to end input.\n");
for (i = 0; i < 10; i++)
{

printf("? ");
scanf ("%i", &accountNumber[i]);

if (accountNumber[i] == -999)
{
printf("\n");

break;
}

scanf("%s", lastName[i]);
scanf("%f", &accountBalance[i]);

} /* End for loop */

printf("%-15s%-15s%-15s\n","ACCOUNT","LAST NAME","BALANCE");

for(i = 0; (i < 10) && (accountNumber[i] != -999); i++)
{

printf("%-15d%-15s%-15.2f", accountNumber[i],
lastName[i], accountBalance[i]);

printf("\n");
}

printf("\n\n");

return 0;

} /* End main */

Using the - modifier in the format left justifies the result within
the field. Removing it causes right justification.

Rgds,

Shanmu,

Wow do I feel silly. I kept looking around the Internet for how to do
it. No wonder I couldn't find it considering it happens by default.
Oh well, thanks for helping me out. :o)
