Program Plan Intro

Program to displays a circle bouncing around the window

Program plan:

Import the required packages

In the “main()” function,

Create the object of “GraphWin()”.

Set the coordinates by calling the function “setCoords()”

Create an object named “shape” and store the points

The outline of the circle is set to “red” color.

The circle is filled with “red” color.

Draw the circle with the use of function “draw()”.

Declare the required variables.

Initialize a for loop to get the value of the points.

Store the center of the circle in “c”.

If the x-value is greater than 80 then

Assign the value of “dx” as “-1”.

If the x-value is less than -80

Assign the value of “dx” as “1”.

If the y-value is greater than 80 then

Assign the value of “dy” as “-1”.

If the y-value is less than -80

Assign the value of “dy” as “1”.

Use the function “sleep()” to slow the program.

Move the circle to the resulting point.

Call the function named “main()”

Write a program that displays an inchworm on the left-hand side of the screen, facing right. Then slowly move him across the screen, until he disappears off the right-hand side. You may wish to do this in a loop so that after disappearing to the right, the worm appears again on the left. The diagram below shows how he may look at various points on the screen. 00 00 000 00 00 00 -000000000 -0000 0000 -000 000 -0000 0000 -000000000 Please do it C++, and show the output as well, thank you

Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints: 0 1 2 3

Write a program that draws a graphic consisting of 50 rectangles with randomly generated sides and 75 located randomly within a 300 by 300 stage. Hint: use a for loop and add each rectangle anonymous rectangle into a pane You will need to set the fill color of each rectangle to TRANSE the stroke to BLACK.
