What is a variable in programming?

• A variable is a command that executes a specific task in programming.

• A variable is a type of function that performs calculations.

• A variable is a fixed value that cannot change during program execution.

• A variable is a symbolic name for a storage location in programming that can hold a value.

Which of the following is a data type: String, Number, or Both?

• Boolean

• Both

• Decimal

• Character

What does an if statement do?

• An if statement always executes all code regardless of conditions.

• An if statement is used to declare variables.

• An if statement is a type of loop that repeats code.

• An if statement executes code based on a condition being true.

What is the purpose of a function?

• To define the main entry point of a program.

• To execute code only once during a program's runtime.

• To create variables for data storage.

• The purpose of a function is to encapsulate code for specific tasks, allowing for reuse and better organization.

How do you declare a variable in most programming languages?

• let variableName value;

• variableName : value;

• To declare a variable, use the syntax: type variableName = value; or simply variableName = value; depending on the language.

• declare variableName as value;

What is a loop used for?

• To store data temporarily.

• To repeat a block of code multiple times.

• To define a function.

• To create a new variable.

What is the difference between a while loop and a for loop?

• The main difference is that a while loop checks the condition before each iteration, while a for loop is used for a specific number of iterations or over a collection.

• A while loop is used for infinite iterations only.

• A for loop can only iterate over arrays.

• A while loop is always faster than a for loop.

What is an algorithm?

• A complex mathematical theorem.

• A random guess for a solution.

• An algorithm is a step-by-step procedure for solving a problem.

• A programming language syntax.

What does debugging mean?

• Testing software for user experience

• Improving software performance

• Finding bugs in hardware

• Debugging means identifying and fixing errors in software.

What is the purpose of logical operators?

• To perform arithmetic calculations on numbers.

• To compare string values for equality.

• To format data for display in user interfaces.

• The purpose of logical operators is to perform operations on boolean values to determine the truth value of expressions.
