Top Programming Interview Questions And Answers
So, without any further ado, here we go:
Question: Please explain what you understand by computer programming.
Answer: Also known as coding or programming, computer programming is the process of encoding an algorithm into a notation, typically a computer program, by means of some programming language so that it can be executed by a computer.
Each programming language contains a set of instructions for the computer to execute a set of tasks. Programming is a complex process that includes designing an algorithm, coding the same in a programming language, debugging a program, maintaining, and updating the code.
Question: Can you enumerate and explain the various types of errors that can occur during the execution of a computer program?
Answer: Three types of errors can occur during the execution of a computer program. These are:
Question: Please explain an algorithm. What are some of its important features?
Answer: An algorithm can be defined as a set of finite steps that when followed helps in accomplishing a particular task. Important features of an algorithm are clarity, efficiency, and finiteness.
Question: What do you understand by maintaining and updating a computer program?
Question: Please provide a brief explanation on variables.
Answer: Variables are used for storing the input of a program as well as the computational results during program execution. These are actually named memory locations. The value stored in a variable can change during the program execution.
What Is The Internet
The internet is a worldwide network of computers and devices that enables people to share information, ideas, and products. It is made up of many different types of networks, such as the internet, mobile networks, and satellite networks. The internet is used for a variety of purposes, including communication, learning, and entertainment. The internet was originally created to allow people to share information and ideas. Today, it is used for a variety of other purposes, including communication, learning, and entertainment. The internet is also an important part of the economy by connecting people around the world.
What Is The Difference Between A Default Constructor And A Conversion Constructor
When preparing for your interview, consider that interviewers may ask you to distinguish between two similar terms. This further tests your technical expertise, especially around more advanced topics. While answering these questions concisely is still important, they also allow you to demonstrate more insight into a given subject.
Example:’Default constructors contain no arguments. If they do have arguments, they all contain default argument values. A conversion constructor, on the other hand, usually has one argument that’s different in value to the others and uses this as a method of conveying conversion rules to a class.’

Which Programming Languages Do You Prefer And Why
This is a very basic question and you should know that there is no right answer to it. If the role you are applying to requires knowledge of a certain language, you can mention some things you like about that particular language. Or you can mention the language you prefer and give the reason for your preference for it. For example:
JavaScript is my favorite language because it is easy to use and it is my primary choice for back-end development. Before JavaScript, websites used to be static, however, after JS the web equation has changed. Now with JS we have features that help build user-friendly and dynamic websites. These are some reasons JS is my favorite programming language to work with.
Computer Science Engineering Interview Questions And Answers
16. What is an Algorithm?
Algorithm is a step-by-step process or set of rules that must be followed in a computer problem solving operation.
17. What is the difference between compilers and interpreters?
The compiler takes all the programs and converts them to object code which is usually stored in files. The object code can be directly executed by the machine after connecting. The interpreter directly executes line-by-line instructions written in a programming language without converting them into object code or machine code.
18. The difference between object oriented programming and procedural programming ?
In procedural programming, the main module is the procedure. These procedures are sequences of imperative statements, such as assignments, tests, repetitions, and calls for sub-procedures. This procedure is a function, which maps arguments to return statements.
In object-oriented programming, the main module in a program is class, not procedure. The object-oriented approach allows you to create classes and objects that model real-world objects.
19. What do you know about SDLC?
SDLC or Software Development Life Cycle is a process that produces the highest quality and lowest cost software in a short time. SDLC involves several different stages, including planning, design, construction, testing, and deployment.

What Is A Class Variable
A class variable is a variable that is defined in a class and shared by all instances of the class. Class variables can be used to store information about an object, such as its name, its location in memory, and its state at any given time. Class variables are often used to store information that is shared by objects in the same class. For example, a class might have a variable called name that is shared by all instances of the class. Class variables are often created with the special keyword class.
Distinguish Between Constructor And Method
The difference between constructor and method is:
| Constructor | |
|---|---|
| Constructor is used for initializing the instance of any class. | Method is used to perform some operation or function. |
| It does not have any return type | It has a return type. |
| The constructor name must be the same as a class name. | The name of the method can be the same or different as per need. |
| It calls automatically when you create a class object. | You need to call the method explicitly. |
| There is a default constructor which is provided by the compiler. | There is no method provided by the compiler. |

It also plays an important role in helping humans make critical decisions based on the data it collects. The programs I’m most familiar with include IBM Watson, Cloud Machine Learning Engine, and TensorFlow.”
What Is The Difference Between Compiler And Interpreter
The difference between compiler and interpreter is:
| Compiler | |
|---|---|
| Compiled code run faster. | Interpreted code run slower. |
| Generates output program , which can be run independently from the original program. | Do not generate an output program. So the programmer evaluates the source program at every time during execution. |
| The target program executes independently and does not require the compiler in the memory. | The interpreter exists in the memory during interpretation. |
| Difficult to implement as compilers cannot predict what happens at turn time. | It is best suited for the program and development environment. |
| It takes an entire program as an input. | It takes a single line of coding as an input. |
| Display all errors after compilation, all at the same time. | Displays all errors of each line one by one. |
