Question: Can we use C STL in coding interviews?

Can I use C in a coding interview?

I recommend that you use a dynamic language like Python, Ruby or JavaScript during interviews. Of course, you should use whatever language you know best. But we find that many people try interviewing in C , C++ or Java, under the impression these are the “real’ programming languages.

Can we use STL in C?

C can’t have an “exact equivalent” of STL because C doesn’t have templates or classes. You might be interested in the “Glib collections” library: http://www.ibm.com/developerworks/linux/tutorials/l-glib/

Is it good to use STL?

STL is well tested and reliable but it is not the fastest solution. Some of the containers allocate a lot of small memory blocks rather than one big block. If you really have a speed problem then you may consider making your own fixed-size list. But for many purposes STL is the standard solution.

Should I use C++ for coding interviews?

‘Real languages’ aren’t necessarily better

Some feel that blazing through a coding challenge in one of these languages will help them stand out among other candidates as more hardcore. Some books on interviewing even flatly recommend that programmers choose Java or C++. This is usually ill-advised.

Which language is best for interview coding?

From my experience as an interviewer, most candidates pick Python or Java. Other commonly seen languages include JavaScript, Ruby and C++.

Can I use Python in coding interview?

(a2a) – Yes, Python is completely accepted in the ivy companies as a coding language. It also depends on the specific role you are interviewing but in general, as long as you know python very well, you can code in it.

What is STL in C programming?

The Standard Template Library (STL) is a set of C++ template classes to provide common programming data structures and functions such as lists, stacks, arrays, etc. It is a library of container classes, algorithms, and iterators.

What is stack in C?

A stack is a linear data structure that follows the Last in, First out principle (i.e. the last added elements are removed first). This abstract data type​ can be implemented in C in multiple ways. One such way is by using an array. ​Pro of using an array: No extra memory required to store the pointers.

How do you handle exceptions in C++?

C++ exception handling is built upon three keywords: try, catch, and throw. throw − A program throws an exception when a problem shows up. This is done using a throw keyword.
…
C++ Standard Exceptions.

Is STL allowed in interview?

You should use STL unless: The question is asking for the same function/data structure, i.e do not use priority_queue or heap functions of STL, if the question is to implement a heap. The questioner mentions it specifically.

Is C++ STL slow?

STL is usually faster at runtime than either C-style solutions with callback pointers or polymorphism-based solutions with virtual methods (see also this Bjarne Stroustrup’s keynote).

Why do we need STL in C++?

Why should a C++ programmer be interested in the STL? Because the STL embodies the concept of reusable software components, and provides off-the-shelf solutions to a wide variety of programming problems.

Which is better for interviews Java or C++?

and if making high performance and fast systems is a priority, C++ is definitely a better choice for those kinds of beginners compared to Java. However, Java offers way more features and easy to use libraries than C++ and therefore, is preferred in the domain of Software Development by a lot of developers.

Are coding interviews hard?

#2) Coding interviews are unnecessarily hard

The difficulty level of most coding interviews is high. This could work well for FAANG companies like Facebook and Google who have access to HUGE pools of highly qualified candidates. In this case, a higher difficulty level could work well to shortlist the best coders.

Does Amazon hire Python developers?

Amazon. This enterprise uses Python due to it’s popularity, scalability, and ability to deal with Big Data.
