Coding Concepts

1. What is an array?

• A. A type of function
• B. A collection of items stored at contiguous memory locations ✓
• C. A programming language
• D. A type of loop

💡 An array stores multiple values of the same type in a single variable with indexed positions.

2. What does "syntax" mean in programming?

• A. The speed of a program
• B. The rules that define the structure of a programming language ✓
• C. The output of a program
• D. The memory used by a program

💡 Syntax refers to the set of rules that define how programs must be written in a specific language.

3. What is a function in programming?

• A. A type of variable
• B. A reusable block of code that performs a specific task ✓
• C. A type of loop
• D. A programming error

💡 A function is a named, reusable block of code that performs a specific task when called.

4. What does "if-else" do in programming?

• A. Creates a loop
• B. Defines a function
• C. Stores data
• D. Makes a decision based on a condition ✓

💡 An if-else statement executes different code blocks based on whether a condition is true or false.

5. What is an algorithm?

• A. A programming language
• B. A type of computer
• C. A step-by-step set of instructions to solve a problem ✓
• D. A computer error

💡 An algorithm is a step-by-step procedure or set of rules for solving a problem or completing a task.

6. What does "boolean" data type store?

• A. Numbers
• B. Text
• C. True or False values ✓
• D. Lists

💡 A boolean data type can only hold one of two values: True or False.

7. What is a loop in programming?

• A. A type of error
• B. A named storage location
• C. A function that runs once
• D. A structure that repeats code multiple times ✓

💡 A loop repeats a block of code multiple times until a condition is met.

8. What is "debugging"?

• A. Writing new code
• B. Deleting old code
• C. The process of finding and fixing errors in code ✓
• D. Running a program

💡 Debugging is the process of identifying, analyzing, and fixing bugs (errors) in a program.

9. What is the purpose of a compiler?

• A. To run a program
• B. To debug code
• C. To translate source code into machine code ✓
• D. To store data

💡 A compiler translates human-readable source code into machine code that a computer can execute.

10. What does "concatenation" mean in programming?

• A. Dividing a string
• B. Reversing a string
• C. Deleting a string
• D. Joining two strings together ✓

💡 String concatenation joins two or more strings together: "Hello" + " World" = "Hello World".
