Is STL library allowed in interviews?

Can STL be used in interviews?

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.

Are libraries allowed in coding interviews?

During a coding interview, you can always ask if you can use such-and-such a function from the library, but generally you can as long as that doesn’t save you from actually having to solve the problem. If you’re asked to implement a sort, for example, you shouldn’t do it by calling the library sort.

Should you use STL?

You should use STL, because it is well tested and optimized. That doesn’t mean you shouldn’t know how to write these data structures yourself. With that ability under your belt, you will be able to choose the best STL data structure for your application.

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/

Can I use sort in interview?

Using sort for a starting point to solving a problem might be okay but your optimal solution is usually going to be a linear solution to most of the coding problems that you’ll be facing in these algorithms interviews. Yes, in general.

Can I use built in functions in interview?

Originally Answered: Is it bad to use built in language features in technical interviews? It depends on how core that built-in library is to the essence of the question. Generally, you shouldn’t replace the essence of the interview question with a built-in library.

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).

Should I use the C++ Standard Library?

You should use standard libraries in all languages, not only C++. That’s pretty much a basic rule in programming these days. Your impression is wrong; any good project will benefit from building upon known, tested, libraries.

Is C++ Standard Library slow?

Large C++ projects can therefore be relatively slow to compile. The problem is largely solved by precompiled headers in modern compilers or using the module system that was added in C++20; future C++ standards are planning to expose the functionality of the standard library using modules.

How STL is different from the C++ Standard Library?

Note that the term “STL” or “Standard Template Library” does not show up anywhere in the ISO 14882 C++ standard. So referring to the C++ standard library as STL is wrong, ie, STL and C++ Standard Library are 2 different things with the former being the subset of the latter.

What is STL in C++ with example?

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 STL programming?

The Statement List (STL) programming language is one of the three programming languages available in the basic STEP 7 software package. It is a text-based programming language with a structure similar to assembly language or machine code. STL is the native language of S7-300 and S7-400 processors.
