Question

Notice that the output-formatting details are not given by the pseudocode, but are implicit in both the output requirements (the “plan”) and the example program output. How should the printf() used to implement the algorithmic step PRINT x be coded to right-justify the loop-control variable x’s value in the required 2-character field?

Answer 1

/*Sample c program that to demonstrate
the left justified with 2 column widh of printing the
value of x as left justified*/
//main.c
//include header file
#include<stdio.h>
#include<conio.h>
int main()
{
   //declare variable,x and set a value, 2 for demonstration
   int x=2;

   /*The 2d is format specifier with 2 space width occupied
   by the x value in left justified.
   Note: If a negative sign is used before format specifier ,
   then x will be printed to left justified.
   */
   printf("%2d",x);

   //pause program output on console
   getch();
   return 0;
}

sample output:

(space)2
