So in class this week were given the following problem to solve:
"Write an application that displays the following patterns separately, one below the other. Use for loops to generate the patterns. All asterisks () should be printed by a single statement of the form Console.Write( "" ); which causes the asterisks to print side by side. A statement of the form Console.WriteLine(); can be used to move to the next line. A statement of the form Console.Write( " " ); can be used to display a space for the last two patterns. There should be no other output statements in the application. [Hint: the last two patterns require that each line begin with an appropriate number of blank spaces.]"
Here is my solution:
1 public static void Main( )
2 {
3 OutputAC( delegate( Int32 xAxis, Int32 i ) { return ( xAxis < i + 1 ); } );
4
5 OutputBD( delegate( Int32 xAxis, Int32 i ) { return ( xAxis < i ); } );
6
7 OutputAC( delegate( Int32 xAxis, Int32 i ) { return ( xAxis > = i ); } );
8
9 OutputBD( delegate( Int32 xAxis, Int32 i ) { return ( i <= xAxis + 1 ); } );
10 Console.ReadLine( );
11 }
12
13 private delegate Boolean CheckCondition( Int32 xAxis, Int32 charactersPerRow );
14
15 private static void OutputAC( CheckCondition condition )
16 {
17 Int32 charactersPerRow = 0;
18 // loop through the y axis from row 0 to 10
19 for ( int yAxis = 0; yAxis < 10; yAxis++ )
20 {
21 // loop through x axis from column 0 to 10 for each row.
22 for ( int xAxis = 0; xAxis < 10; xAxis++ )
23 {
24 // write the character for the current position
25 Console.Write( condition( xAxis, charactersPerRow ) ? "*" : " " );
26 }
27 ++charactersPerRow;
28 Console.WriteLine( );
29 }
30 }
31
32 private static void OutputBD( CheckCondition condition )
33 {
34 Int32 charactersPerRow = 10;
35 for ( int yAxis = 0; yAxis < 10; yAxis++ )
36 {
37 for ( int xAxis = 0; xAxis < 10; xAxis++ )
38 {
39 Console.Write( condition( xAxis, charactersPerRow ) ? "*" : " " );
40 }
41 --charactersPerRow;
42 Console.WriteLine( );
43 }
44 }
