3. Soru

#include<stdio.h>

 int side; // length of side
   int rowPosition; // row counter

   printf( "%s", "Enter the square side: " ); // prompt for side length

   colPosition = side; // set size counter to length of side

   // loop side number of times
   while ( colPosition > 0 ) { 
      rowPosition = side; // set row counter to length of side

      // loop rowPosition number of times
      while ( rowPosition > 0 ) { 

         // if side or row counter is 1 or size print an '*'
         if ( colPosition == side ) {
