3int main()

4{

5 int row;

6 int counter, m, n;

7 printf( "Enter the row of the diamond: " );

8 scanf( "%d", &row );

9

10 //above the max line

11 for ( counter = 1; counter <= ( row - 1 ) / 2; counter++ )

12 {

13 for ( m = 1; m < ( row + 1) / 2 - ( counter - 1 ); m++ )

14 printf( " " );

15 for ( n = 1; n <= 2 * counter - 1; n++ )

16 printf( "*" );

17 printf( "\n" );

18 }

19

20 //max line

21 for ( n = 1; n <= row; n++ )

22 printf( "*" );

23 printf ( "\n" );

24

25 //below the max line

26 for ( counter = 1; counter <= ( row - 1 ) / 2; counter++ )

27 {

28 for ( m = 1; m <= counter; m++ )

29 printf( " " );

30 for ( n = 1; n <= row - ( m - 1 ) * 2; n++ )

31 printf( "*" );

32 printf( "\n" );

33 }

35 return 0;
