10+ Coding Instructor Interview Questions and Answers

Loops, arrays, and conditional statements are fundamental programming concepts.

• Loops allow for repetitive execution of code based on a condition or a set number of iterations.

• Arrays are collections of data that can be accessed and manipulated using an index.

• Conditional statements allow for the execution of different code based on a specified condition.

• Examples: for loop, while loop, do-while loop, if statement, switch statement, foreach loop.

I am comfortable with OOPS programs such as Java, C++, and Python.

• Proficient in Java OOPS concepts such as Inheritance, Polymorphism, and Encapsulation

• Familiar with C++ OOPS concepts such as Abstraction, Constructors, and Destructors

• Experienced in Python OOPS concepts such as Classes, Objects, and Inheritance

A life cycle hook in auto scaling allows you to perform custom actions before an instance is launched or terminated.

• Life cycle hooks can be used to pause the instance launch process to perform custom actions.

• Common actions include validating the instance configuration or setting up additional resources.

• Examples of life cycle hooks include 'Launch' and 'Terminate'.

Print pyramid pattern and reverse it using online compiler

• Use nested loops to print the pyramid pattern

• Start with one '*' in the first row and increase by 2 in each subsequent row

• To reverse the pyramid, start with the maximum number of '*' in the first row and decrease by 2 in each subsequent row

Program to print prime numbers

• Start with a loop from 2 to n (number to check)

• For each number, check if it is divisible by any number from 2 to its square root

• If not divisible, it is a prime number and print it

Coding involves writing instructions for computers to execute tasks, using programming languages like Python, Java, and C++.

• Coding is the process of creating instructions for computers to follow.

• Programming languages like Python, Java, and C++ are used for coding.

• Coding is essential for developing software, websites, and apps.

• Debugging and problem-solving are important skills in coding.

• Coding allows for automation of tasks and creation of innovative solutions.

Polymorphism is the ability of an object to take on many forms.

• It allows objects of different classes to be treated as if they are of the same class.

• It is achieved through method overriding and method overloading.

• Example: A shape class can have different subclasses like circle, square, and triangle, but they can all be treated as shapes.

• Example: The + operator can be used to add integers, floats, and strings, demonstrating polymorphism through operator overloading.

Code in the code.org platform

• Use block-based coding to create programs

• Drag and drop blocks to sequence commands

• Test and debug your code to ensure it runs correctly

Inheritance is a concept in object-oriented programming where a class inherits attributes and methods from another class.

• Allows for code reusability by creating a new class based on an existing class

• Child class can access and modify the attributes and methods of the parent class

• Helps in creating a hierarchy of classes with shared characteristics
