Let’s practice Some Challenging Programming interview questions
posted:3 years agobyMarry JoJoin Interviews
Complete understanding of fundamental of coding is a requisite for coding, software development or analyst job. In this post, I would like to unlock some basic programming interview questions for a quick memory refresh. In a programming interview, the interviewer tests your knowledge about algorithms and data structures. Even you need to read some answers and examples for programming technical and logical interview questions.
1. What is programming? How does it work?
Programming unlocks a set of instructions which are given to the computer for performing varied tasks. Every instruction is an executable command which has its specific purpose.
2. Why is String Final in Java?
Another programming interview question Java is to test your understanding of simple String concept. Every Java designer knows that string is immutable and they finalized it from very start. He optimized string and make it final, since this element is going to be used widely in every single Java program.
3. What you know about Debugging?
It is a process through which a programmer find and remove error found in a program. Nullable types are used for debugging. Nullable types are specific data types which contain normal values and also define the data type for null. Programming integrates them with C#, which is compatible with nullable types and value types. In a debugging process, a program declares a nullable type in C#. The syntax for declaration is? =null;
A program is checked thoroughly to identify the errors. It will list the errors; a programmer will check them end and remove them from the program.
4. How You split a String?
Java programmer gets help from Java API for splitting a string. There are multiple ways to perform this task like using any delimiter such as a comma, colon, and semicolon.
5. What is the difference between String and StringBuilder in Java?
It is a standard programming interview question related to Java. Let’s answer it. A string is immutable while StringBuilder is mutable. When it comes to Temporary String manipulation, a String builder is used because it doesn’t synchronize.
6. What is a Low-level programming language?
It is a kind of programming language that doesn’t have any generalization from a computer’s “instruction set architecture”. It heads on to machine code or assembly language.
7. What is meant by High-level Programming language?
In computer programming, many developers prefer to high-level programming language over low-level language because it lets them use natural language elements in it. This type of programming language offers high generalization from a computer’s “instruction set architecture”.
8. What is Machine code?
It is a language in which a microprocessor can process directly without any transformation requirements. A programmer doesn’t write directly in machine code. He writes in other programming languagess and then transforms it so that a computer can process it.
9. What is the use of Generics in C#?
It is one of the essential programming interview questions C#. The reason for asking this question is to know whether you can encompass all basic concepts of C# language. Make sure you provide its answer by outlining the best features of generics, once you define what generics are.
Developer use generics for defining a class, method, event or interface that accept any kind of data type. Generics put a pause on the specification of programming elements’ data types until a programmer needs to add them in a specific class, event or interface. The best thing about Generics is that they allow a programmer to reuse C# code again and again. The system is safe and highly optimized in terms of performance. You can get real-time information about the types used in the generic data time at the Runtime through reflection.
10. What is a nested loop?
When a loop is running within another loop, then it is named as a nested loop. The first loop is known as the outer loop while the loop inside it known as the inner loop.
11. Is it okay to use curly brackets ({}) to enclose a single line code in C program?
Yes, it is okay. Many programmers employ this method to organize their code. But curly brackets are typically used to enclose a group of several code lines. It is one of those programming interview questions which are asked with an intent to know what you do and how other programmers do it.
What else to prepare as Programming Interview Questions?
I highlighted only the basic questions which are commonly asked in a programming interview. You also need to focus on some other concepts of programming. An interview may ask some questions related to Binary tree coding, String coding, Linked List, Array coding and Algorithms. As you signed up for a software developer or analyst job in Pakistan that means you must know about another programming language such as PHP, Java, Jquery, SQL, etc.
I know it’s a lot to take in. Worry not!
Here you can check
They are short but fundamental programming interview questions. Go through them, and I’m sure you will land on your programmeri job position in Pakistan after having a successful interview.
