Program Plan Intro

“if” statement:

 “if” statement is used to make a decision structure, which permits the program to hold more than one path of execution.

  • • The indented statement is executed only when the condition is “true”.
  • • If the given condition is “false”, it skips the indented statements.

Turtle:

Turtle graphics is a method which is used to simulate a “turtle” to draw a simple graphics based on the given commands.

  • • It provides numerous functions that use decision structures which determines the state of a turtle and performs actions according to the conditions.

Import turtle:

A turtle is the predefined module in a program and in order to use the turtle in a program the turtle module must be imported.

  • • To import the turtle module use “import turtle” in the program.

Algorithm:

Algorithm to determine whether the turtle’s pen color is “red” or “blue”

  • • Check whether the pen color is “red” or “blue”.
  • • If so, then make the pen size to “5” pixel using the function “pensize()”.

(Geometry: point in a circle?) Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the circle centered at (0, 0) withradius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, asshown in Figure 3.7a.(Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10.The formula for computing the distance is 2(x2 - x1)2 + (y2 - y1)2. Test yourprogram to cover all cases.) Two sample runs are shown below:   Enter a point with two coordinates: 4 5Point (4.0, 5.0) is in the circleEnter a point with two coordinates: 9 9Point (9.0, 9.0) is not in the circle
What happens if you push Enter when the emphasis is on a Button control?
The only way to start debugging was to hit "F5" or click the "Start Debugging" button. Visual Studio switches to debug mode when an error is thrown.
