Problem Solving through Programming

1. What is the primary purpose of a variable in a program?

• A) To define functions
• B) To display output
• C) To store any information
• D) To perform calculations

2. Which Python function is used to display output on the screen?

• A) input()
• B) display()
• C) show()
• D) print()

3. Which of the following statements accurately describes Python's handling of case-sensitivity for variable names?

• A) Python treats `my_variable` and `My_variable` as the same variable.
• B) Python is not case-sensitive for variable names.
• C) Python treats `my_variable` and `My_variable` as two different variables.
• D) Only the first letter of a variable name is case-sensitive.

4. According to the text, which programming language is recommended as an excellent starting point for those new to programming?

• A) C++
• B) Java
• C) C
• D) Python

5. Which of the following is an INCORRECT variable name in Python, based on the naming rules provided in the text?

• A) `my_variable`
• B) `_count`
• C) `if`
• D) `variable123`

6. What is a key difference in how a compiler and an interpreter handle errors during the translation of programming instructions?

• A) A compiler translates line by line, while an interpreter translates all at once.
• B) A compiler stops on the first error, while an interpreter continues translating despite errors.
• C) A compiler translates all instructions at once and stops if any error is found, while an interpreter translates sequentially and stops on an error in any instruction.
• D) An interpreter only translates error-free code, while a compiler can translate code with minor errors.

7. If a user inputs '123' into a program using the `input()` function, what will be the data type of the stored value in Python?
