Pseudocode vs Real Code Examples

Example 1 - Basic Login Logic

Check if a user is logged in and display either a dashboard or a login page based on their login status.

Pseudocode:

START
Check if the user is logged in
IF logged in
    Display user dashboard
ELSE
    Display login page
END

Python Example:

if user.is_logged_in():
    display_dashboard(user)
else:
    display_login_page()

Explanation:

• The code checks if the user is logged in using a method is_logged_in() on the user object.
• If the user is logged in, their personalized dashboard is displayed using the display_dashboard() function.
• If they are not logged in, the display_login_page() function is called to show the login screen.

---

JavaScript Example:

// Check if the user is logged in
if (user.isLoggedIn()) {
    // Display user dashboard
    displayDashboard(user);
} else {
    // Display login page
    displayLoginPage();
}

Explanation:

• The user.isLoggedIn() function checks if the user is logged in.
• If the user is logged in, the displayDashboard(user) function is called to display the dashboard.
• Otherwise, the displayLoginPage() function is called to display the login page.

---

C# Example:

// Check if the user is logged in
if (user.IsLoggedIn())
{
    // Display user dashboard
    DisplayDashboard(user);
}
else
{
    // Display login page
    DisplayLoginPage();
}

Explanation:

• IsLoggedIn() is a method that checks if the user is logged in.
• DisplayDashboard(user) is called if the user is logged in, and DisplayLoginPage() is called otherwise.

Example 2 - Variable & While Loop

Use a variable and a loop to output numbers from 1 to 5.

Pseudocode:

START
Set variable 'i' to 1
WHILE 'i' is less than or equal to 5
    Print 'i'
    Increment 'i' by 1
END WHILE
END

---

Python Example:

# Set variable i to 1
i = 1

# While i is less than or equal to 5
while i <= 5:
    # Print i
    print(i)
    # Increment i by 1
    i += 1

Explanation:

• A while loop is used to print the value of i from 1 to 5.
• The loop continues as long as i is less than or equal to 5.
• The variable i is incremented by 1 in each iteration.

---

C# Example:

// Set variable i to 1
int i = 1;

// While i is less than or equal to 5
while (i <= 5)
{
    // Print i
    Console.WriteLine(i);
    // Increment i by 1
    i++;
}

Explanation:

• Similar to Python, a while loop is used.
• The Console.WriteLine(i); statement prints the value of i in each iteration.
• The variable i is incremented by 1 using i++.

---

JavaScript Example:

// Set variable i to 1
let i = 1;

// While i is less than or equal to 5
while (i <= 5) {
    // Print i
    console.log(i);
    // Increment i by 1
    i++;
}

Explanation:

• In JavaScript, the console.log(i); statement is used to print the value of i to the console.
• A while loop runs as long as i is less than or equal to 5, incrementing i by 1 after each iteration.

Each language handles the loop and printing in a slightly different way, but they all follow the same logic outlined in the pseudocode.
