What is a variable in programming?
✔✔A variable in programming is a named storage location in memory that holds a value, which
can be changed during program execution.
What are the common data types used in programming?
✔✔Common data types used in programming include integers, floating-point numbers,
characters, strings, and booleans.
What is the purpose of a control structure in programming?
✔✔The purpose of a control structure is to dictate the flow of execution in a program, allowing
for decision-making and repeated actions based on certain conditions.
What is the difference between a function and a procedure?
✔✔A function is a block of code that performs a specific task and returns a value, while a
procedure (or subroutine) performs a task but does not return a value.

,What is an algorithm?
✔✔An algorithm is a step-by-step procedure or formula for solving a problem or completing a
task, typically expressed in a structured way.
How do you perform error handling in programming?
✔✔Error handling in programming involves anticipating and managing potential errors using
techniques like try-catch blocks, exception handling, and validation checks.
What is a loop, and why is it used?
✔✔A loop is a control structure that allows for repeated execution of a block of code as long as a
specified condition is true, helping to automate repetitive tasks.
What are arrays, and how are they used in programming?
✔✔Arrays are data structures that store multiple values of the same type in a single variable,
allowing for efficient access and manipulation of collections of data.
What is the significance of comments in code?
✔✔Comments are used to annotate code, providing explanations or notes for developers, which
improves code readability and maintainability.
2
, What is the concept of scope in programming?
✔✔Scope refers to the visibility or lifetime of a variable within a program, determining where a
variable can be accessed or modified.
What is recursion, and how does it work?
✔✔Recursion is a programming technique where a function calls itself to solve smaller instances
of the same problem, with a base case to terminate the recursive calls.
What is the difference between a stack and a queue?
✔✔A stack is a data structure that follows the Last In, First Out (LIFO) principle, while a queue
follows the First In, First Out (FIFO) principle.
What is object-oriented programming (OOP)?
✔✔Object-oriented programming (OOP) is a programming paradigm that uses objects to
represent data and methods to manipulate that data, focusing on concepts like encapsulation,
inheritance, and polymorphism.
