Basic Computer Programming Questions For Beginners! Quiz

1. A do while and a while loop are the same

True

False

A do while loop and a while loop are not the same. The main difference is that a do while loop executes the code block at least once before checking the condition, whereas a while loop checks the condition first and executes the code block only if the condition is true. Therefore, the correct answer is False.

Explanation

A do while loop and a while loop are not the same. The main difference is that a do while loop executes the code block at least once before checking the condition, whereas a while loop checks the condition first and executes the code block only if the condition is true. Therefore, the correct answer is False.

2. C is object-oriented

True

False

Assume C not C++

Explanation

Assume C not C++

3. A memory location that holds a single letter or number.

Double

Int

Char

Word

A char is a data type in programming that is used to store a single letter or number. It is a memory location that can hold a single character. The other options, such as double and int, are used to store numbers with decimal points and whole numbers respectively. The option "word" is not a valid data type in programming. Therefore, the correct answer is char.

4. What is a pointer?

A finger

A ruler

A reference to some chunk of memory

Option 4

A pointer is often used in computer programming to refer to a memory location. It is similar to a finger that points to a specific location in memory. By using a pointer, programmers can access and manipulate data stored in that memory location. Therefore, the analogy of a finger is used to explain the concept of a pointer in a relatable way.
