In MSWLogo, the REPEAT
command allows you to execute a set of instructions multiple times. The syntax is REPEAT <number> [commands]
, where <number>
specifies how many times to repeat the enclosed commands. For example, REPEAT 4 [FORWARD 100 RIGHT 90]
would move the turtle forward 100 units and then turn right 90 degrees, repeating this sequence four times to create a square. This command is useful for creating patterns and shapes efficiently.
To create a curved line in MSWLogo, you can use the REPEAT command combined with the FORWARD and RIGHT (or LEFT) commands. For example, you can draw a quarter-circle by repeating a small forward movement and a slight turn: REPEAT 36 [FORWARD 5 RIGHT 10]. Adjust the values to change the curvature and size of the arc as needed.
To create a house in MSWLogo, start by using the REPEAT command to draw the square base of the house. Use commands like FORWARD and RIGHT to navigate and shape the walls. Next, use the TRIANGLE command or a combination of lines to create the roof. Customize your house by adding windows and a door with smaller shapes using similar commands.
To draw a square using MSWLogo, you can use the REPEAT command to create the four equal sides. Enter the following commands in the command window: REPEAT 4 [FORWARD 100 RIGHT 90] This code instructs the turtle to move forward 100 units and then turn right by 90 degrees, repeating this process four times to complete the square. Adjust the number in FORWARD to change the size of the square.
To draw a boat in MSWLogo, you can use simple commands to create the shape. Begin by using the REPEAT command to create the hull, using FORWARD and RIGHT or LEFT to form the angles. Add details like sails or waves with additional shapes and lines. For example, you could use PENUP and PENDOWN to move the turtle without drawing while positioning the sails.
To make a tree in MSWLogo, you can use the "repeat" command to create the trunk and branches. Start by drawing a straight line for the trunk using the "fd" (forward) command. Then, use the "lt" (left) and "rt" (right) commands to create branches by changing the angle of the turtle. You can use the "repeat" command to create multiple branches, adjusting the angle and length each time. Finally, you can add leaves by drawing small circles or shapes at the end of each branch.
A decagon is a 10-sided polygon. To draw a regular decagon in MSWLogo, first create the following procedure: to decagon :n repeat 10 [fd :n rt 36] end Now invoke it: decagon 100 This creates a decagon with sides of length 100.
To draw an oval in MSWLogo, you can use the REPEAT command to create a series of small line segments that approximate the shape of an oval. For example, you can use a command like REPEAT 360 [FORWARD 1 RIGHT 1] to create a circular shape, and then adjust the horizontal and vertical scaling to create an oval effect. Alternatively, you can use the ARC command to draw a part of an oval by specifying the radius and angle.
To create a smiley face in MSWLogo, you can use a combination of drawing commands. First, draw a circle for the face using the REPEAT command to create a rounded shape. Next, use simple shapes like circles or lines to add eyes and a curved line for the smile. Here's a sample code snippet: ; Draw face REPEAT 36 [FORWARD 10 RIGHT 10] ; Position for eyes PENUP FORWARD 20 RIGHT 90 FORWARD 30 PENDOWN ; Draw eyes REPEAT 2 [CIRCLE 5 PENUP FORWARD 20 PENDOWN] ; Draw smile PENUP BACK 30 RIGHT 90 PENDOWN LEFT 90 FORWARD 10 RIGHT 90 REPEAT 18 [FORWARD 1 RIGHT 10] This will create a simple smiley face on the screen.

Most programming languages have some loop construct, that make it possible to repeat commands several times. The available commands vary, depending on the language; as an example, Java has the "for", "while", and "do...while" keywords.
