Login and Password Checker Pseudo Code

Objective

Create a basic login system that verifies a user’s username and password.

Pseudo Code

Initialize User Database

1. Create a dictionary or hash table to store user credentials:
   • Key: Username
   • Value: Password

initialize user_database as dictionary
add entry to user_database with key 'username1' and value 'password1'
add entry to user_database with key 'username2' and value 'password2'

Define Login Function

2. Define a function to check login credentials:
   • Input: username and password
   • Output: Success or failure message

define function check_login(username, password)
    if username exists in user_database then
        if user_database[username] equals password then
            return "Login successful"
        else
            return "Incorrect password"
    else
        return "Username not found"

Get User Input

3. Prompt user to enter username and password.

ask user to input username and store in variable user_input_username
ask user to input password and store in variable user_input_password

Call Login Function

4. Use the provided user input to call the login function and display the result.

result = check_login(user_input_username, user_input_password)
display result

Full Pseudo Code

Combining all the above steps, the full pseudo code will look like this:

initialize user_database as dictionary
add entry to user_database with key 'username1' and value 'password1'
add entry to user_database with key 'username2' and value 'password2'

define function check_login(username, password)
    if username exists in user_database then
        if user_database[username] equals password then
            return "Login successful"
        else
            return "Incorrect password"
    else
        return "Username not found"

ask user to input username and store in variable user_input_username
ask user to input password and store in variable user_input_password

result = check_login(user_input_username, user_input_password)
display result

Notes

• Ensure sensitive data handling practices for storing and verifying passwords.
• This pseudo code assumes that the password is stored in plaintext, which is not recommended for production systems. Instead, consider using hashed passwords with salt for security purposes.
