S4: Arrays and Input Validation

What is the format of the following arrays:

["apple", "banana", "grape"] ​ (a)  
[True, False, True, False]​ ​ (b)  

[3.14, 2.71, 1.62]​ (c)  

• String
• Boolean
• Real

Identify the following statements as related to either '1D arrays' or 'Input Validation':

Groups:

(a) Checking if an email contains an "@"

,

(b) Accessing the third element using index

• Input Validation

• 1D Arra

In Python, to ensure that an inputted age is between 0 and 100, which conditional statement is correct?

• if age < 0 and age > 100

• if age > 0 or age < 100

• if 0 <= age <= 100

• if age == 0 or age == 100

Match the following

• Validating if an input is an integer

• arr = ["a", "b", "c"]

• Input validation

• if type(value) == int

• 1D Array

• Ensuring a user enters a valid age between 0 and 120

• Declaration of a 1D array

• Storing multiple values in a single data structure

Given the array:

fruits = ["apple", "grape", "banana"]

What will fruits[0] return?

• Apple

• Grape

• Bannana

• Error

Which of the following is a type of input validation?

• Concatenation

• Range check

• Iteration

• Addition

Reorder the following

• print("Valid number entered.")

• if 1 <= num <= 10:

• num = int(input("Enter a number between 1 and 10: "))

What does the following code do?

value = input("Enter a value: ")

if not value.isdigit():

print("Invalid input. Please enter a number.")

• Checks if the inputted value is a string

• Checks if the inputted value is a valid number

• Converts the inputted value to an integer

• None of the above

Which of the following best defines a standard algorithm?

• A specific programming language used to write software.

• A set of guidelines on how to name variables in code.

• A universally recognized step-by-step method used to solve a particular category of problems.

• A tool used to test software applications.

______ ensures that the user input meets certain criteria before it is processed in the program.
