Introduction

By default, all output is right justified.

To left justify, place a minus sign directly after the %.

For example, %-10.2f left-justifies a floating -point number with two decimal places in a 10-character field.

The following program illustrates left justification:

Demo Code

#include <stdio.h>

int main(void)
{
   printf(".........................\n");
   printf("right-justified: %8d\n", 100);
   printf(" left-justified: %-8d\n", 100);

   return 0;/*  w  w w. j  av a2  s.  com*/
}
