What are some good coding round questions for freshers in C. What is the best interview question ever.
Here are a couple, some I have been asked in interviews, some I made up on the spot. Most of them are conceptual but it’s not uncommon for interviewers to ask conceptual questions, especially to beginners.For an entry level position, it should be a learning period for a coder. However you should judge him whether he has basic knowledge of coding/programming. Here are some of the coding round questions for freshers in c
What is object-oriented programming? Why is this paradigm so useful for software design?
What are the differences between static and dynamic typed languages? What are the advantages/disadvantages of both?
What is a depth first search? What is a breadth first search? Which search would be better for, say, finding directions using a map/navigation app?
What is big O notation? Why is it useful for programmers?
Write a program that prints the first 100 prime numbers. What is a way that you can speed up this task? (The 2nd part is more of a math question than a programming one. Math skills are usually a plus when hiring programmers, but not a must.)
1. What’s debugging? Give an example why debugging is important.
(This question will test whether he/she believes in quality)
2. What’s an API? Share a use case for any third party API you used in any of your programs.
(This question will test his/her knowledge of software architecture)
3. How do you manage writing a program having more than 1000 lines of code?
(This question will test whether he/she is an organized coder)
4. Do you think OOP is a good coding methodology? Why or why not?
(This question will test whether he/she understands importance of using good programming styles)
5. For a large enough program, would you consider using a functions library or would you prefer coding everything by yourself?
(This question will test whether he/she believes in collaboration and reusability)
To me I think these are few of the important areas of coding knowledge for a fresher to know. These are some of the coding round questions for freshers in c.
Below are the c programs questions for freshers that were asked in the coding round, categorized section-wise.
