A programmer is designing a flowchart to represent a simple login system. The flowchart includes a decision symbol that checks if the username and password match the stored credentials. What will happen if the decision symbol is removed?

• The flowchart will still work but become more complex

• The flowchart will loop indefinitely without making a decision

• The flowchart will fail to validate user credentials

• The flowchart will function the same way but be harder to read

A process symbol is used instead of a decision symbol to check if a number is even or odd in a flowchart. What will be the impact?

• The flowchart will still work correctly

• The flowchart will not provide correct results

• The flowchart will take longer to execute

• The flowchart will be more efficient

A programmer designs a flowchart for a simple ATM withdrawal system. The decision symbol checks if the balance is greater than the withdrawal amount. If true, it proceeds to dispense cash; otherwise, it ends the process. What critical component is missing?

• A step to deduct the withdrawal amount from the balance

• A loop to repeat the process for multiple withdrawals

• A second decision symbol to check if the ATM has enough cash

• A process to print the transaction receipt

A system requires users to enter both a username and password. The system must check the credentials and, if they are incorrect, prompt the user to try again. The correct flowchart should include a loop that repeats the input process until valid credentials are provided.
