Pseudo Code for Opening a Web Browser

Objective

This pseudo code outlines the process of opening a web browser such as Chrome, Microsoft Edge, or Firefox on a user's device.

Assumptions

• The user has at least one of the specified web browsers installed on their system.
• The necessary permissions to access and launch applications are granted.

Main Steps

1. Check for installed browsers
2. Prompt user to select a browser if multiple options are available
3. Open the selected browser

Pseudo Code

BEGIN

   // Step 1: Define list of available browsers
   DECLARE browsers AS LIST OF STRING
   browsers = ["Chrome", "Edge", "Firefox"]

   // Step 2: Check if browsers are installed
   DECLARE installedBrowsers AS LIST OF STRING
   installedBrowsers = GET_INSTALLED_BROWSERS()

   // Step 3: Filter installed browsers
   DECLARE availableBrowsers AS LIST OF STRING
   FOR EACH browser IN browsers DO
       IF browser IN installedBrowsers THEN
           ADD browser TO availableBrowsers
       END IF
   END FOR

   // Step 4: Check if any browsers are available
   IF LENGTH(availableBrowsers) = 0 THEN
       PRINT "No browser installed."
       RETURN
   END IF

   // Step 5: Prompt user for selection if multiple browsers exist
   IF LENGTH(availableBrowsers) > 1 THEN
       PRINT "Select a browser to open:"
       FOR EACH browser IN availableBrowsers DO
           PRINT browser
       END FOR
       DECLARE userChoice AS STRING
       userChoice = GET_USER_INPUT()
   ELSE
       userChoice = availableBrowsers[0]
   END IF

   // Step 6: Open the selected browser
   OPEN_BROWSER(userChoice)

END

Explanation of Pseudo Code Components

• Step 1: A list of common browsers is defined for reference.
• Step 2: The program checks for installed browsers on the user's system.
• Step 3: It filters the list to create a list of only those browsers that are available on the system.
• Step 4: The program checks if any browsers are available. If none are found, it informs the user and exits.
• Step 5: If multiple browsers are available, the user is prompted to select one. If only one browser is found, it is automatically selected.
• Step 6: The selected browser is opened using a defined function that handles the action.

This pseudo code serves as a structured guide for implementing the functionality to open a web browser and can be easily adapted to specific programming languages or environments.
