Raptor Programming

 RAPTOR (Rapid Algorithmic Prototyping Tool for Ordered Reasoning) is a flowchart-based programming tool designed to help users visualize algorithms. Here are some examples of simple RAPTOR programs:                                             Program 1: Print ‘Welcome` message on the screen                                                                                 Step 1: Open RAPTOR

• Launch the RAPTOR application on your computer.

Step 2: Create a New Flowchart

• Start a new flowchart by selecting "New" from the menu.

Step 3: Add a Start Symbol

• Drag the Start symbol (oval shape) onto the workspace. This indicates the beginning of your program.

Step 4: Add an Output Symbol

• Drag an Output symbol (parallelogram shape) onto the workspace.

• Connect it to the Start symbol by dragging a line from Start to Output.

Step 5: Configure the Output Symbol

• Double-click on the Output symbol to open its properties.

• In the text box, type "Welcome" (including quotes) to display this message when the program runs.

Step 6: Add an End Symbol

• Drag an End symbol (oval shape) onto the workspace.

• Connect it from the Output symbol to indicate that the program will terminate after displaying the message.

Step 7: Run Your Program

• Click on the "Run" button (play icon) in the toolbar to execute your flowchart.

• A dialog box should appear displaying "Welcome".

Flowchart Overview

Your flowchart should look like this:

[Start] --> [Output: "Welcome"] --> [End]

                                                        Program2:Addition of 2 numbers.          

 Step 1: Open RAPTOR

- Launch the RAPTOR application on your computer.

 Step 2: Create a New Flowchart

- Start a new flowchart by selecting "New" from the menu.

Step 3: Add a Start Symbol

- Drag the Start symbol (oval shape) onto the workspace to indicate the beginning of your program.

 Step 4: Add Input Symbols

- You will need two Input symbols (parallelogram shapes) to get the numbers from the user.

- Drag the first Input symbol onto the workspace. Connect it to the Start symbol.

- Double-click on this Input symbol and set its prompt to `"Enter the first number:"`. Assign a variable name, for example, `num1`.

- Drag a second Input symbol onto the workspace. Connect it to the first Input symbol.

- Double-click on this second Input symbol and set its prompt to `"Enter the second number:"`. Assign a variable name, for example, `num2`.

 Step 5: Add a Calculation Symbol

- Drag a  Process symbol (rectangle shape) onto the workspace. Connect it to the second Input symbol.

- Double-click on this Process symbol and enter the expression for summing the two numbers. For example:

  

  sum = num1 + num2

 

  Here, `sum` is a new variable that will hold the result of the addition.

 Step 6: Add an Output Symbol

- Drag an **Output** symbol onto the workspace and connect it to the Process symbol.

- Double-click on this Output symbol and set its message to:

  

  "The sum is: " + sum

  

  This will display the result of the addition when executed.

Step 7: Add an End Symbol

- Finally, drag an **End** symbol (oval shape) onto the workspace and connect it from the Output symbol to indicate that the program will terminate after displaying the result.

 Step 8: Run Your Program

- Click on the "Run" button (play icon) in the toolbar to execute your flowchart.

- Follow the prompts to enter two numbers, and you should see their sum displayed.

Flowchart Overview

Your flowchart should look like this:

```

[Start] 

   |

[Input: "Enter first number"] --> [Input: "Enter second number"]

   |                                       |

[Process: sum = num1 + num2] |

   |

[Output: "The sum is: " + sum]

   |

[End]
