Pseudo Code for Grass and Flower Drawing

1. Grass Drawing Function (grass2)

• Purpose: To draw a grassy area on the canvas.
• Details:
  • The grass is represented as a dark green filled rectangle at the bottom of the canvas.

Pseudo Code

FUNCTION grass2():
    PEN UP                            // Lift the pen to move without drawing
    GOTO position (-450, 0)          // Move to starting position
    SET HEADING to 0                  // Face right (0 degrees)
    PEN DOWN                          // Start drawing

    FILL COLOR 'darkgreen'            // Set fill color for grass
    BEGIN FILL                       // Start filling the shape
        FORWARD 900                   // Draw the bottom edge of the grass
        TURN RIGHT 90                 // Turn to face upwards
        FORWARD (450 / 3)             // Draw the left height of the grass
        TURN RIGHT 90                  // Turn to face left
        FORWARD 10                     // Draw the thickness of the grass
        PEN COLOR 'darkgreen'         // Change pen color to match the grass
        FORWARD 890                   // Draw the top edge of the grass
        TURN RIGHT 90                  // Turn to face downwards
        PEN COLOR 'black'              // Change pen color to black
        FORWARD (450 / 3)              // Draw the additional height
    END FILL                        // End the fill process

2. Flower Drawing Function (flower)

• Purpose: To create a flower at a specified position.
• Details:
  • The flower consists of multiple yellow circles for petals and white filled circles for its center.

Pseudo Code

FUNCTION flower():
    PEN COLOR 'deeppink'              // Set pen color for flower details
    PEN SIZE 3                        // Set thickness of the pen
    SET HEADING to 0                  // Face right (0 degrees)
    PEN UP                            // Lift the pen
    GOTO position (-375, -80)         // Move to starting position for the flower

    FOR x FROM 0 TO 8                 // Loop to create petals
        FILL COLOR 'yellow'            // Set fill color for petals
        BEGIN FILL                   // Start filling petal shape
            PENDOWN                   // Start drawing the petal
            CIRCLE(10, extent = 360)  // Draw a full circle for petal
        END FILL                    // End filling the petal

        FOR b FROM 0 TO 7             // Create additional petal shapes
            CIRCLE(10, extent = 45)   // Draw part of a petal
            FOR i FROM 0 TO 7         // Loop to create center of flower
                FILL COLOR 'white'      // Set fill color for center
                BEGIN FILL           // Start filling center
                    CIRCLE(-8, extent = 360) // Draw the center circle
                END FILL            // End filling center
        PEN UP                        // Lift the pen
        SET HEADING to 0              // Face right again
        FORWARD 90                    // Move forward by 90 units to place the next flower

Summary

The two functions grass2 and flower are designed to create a visual representation of grass and a flower using a graphical interface. The grass is formed as a filled rectangle, while the flower consists of several shapes that represent its petals and center. Each function employs basic drawing commands, movement operations, and control structures such as loops to achieve the desired outcome.
