int

while(Counter>0) //Initailly my "Counter" is set to
total no. of elemnet in my 2-D array. so now I will
decrement it as I cover a element.

{

i=d;j=d;

while(j<Current_column_size-1) {
printf("%d\t",a[i][j]); j++; Counter--;}
//this is for printing the first row in forward direction.

while(i<Current_row_size-1) {
printf("%d\t",a[i][j]); i++; Counter--;}
//this is for printing the last cloumn in downward direction.

while(j>d) {
printf("%d\t",a[i][j]); j--; Counter--; }
//this is for printing the last row in backward direction.

while(i>d) {
printf("%d\t",a[i][j]); i--; Counter--; }
//this is for printing the first column in upward direction.

//When I completed the outer rectangle I move in to inner
rectangle by incrementing "d".

//and decrementing the "Current_row_size" and
"Current_column_size".
d++;
Current_row_size--;
Current_column_size--;
