Written by the creator of C++, it’s no surprise that many of its functions are useful and powerful, even to this day. However, there are some lesser-known functions that can make your coding easier, or even more fun. We’ve collected 5 useful C++ functions you may not know about yet, so keep reading!

1)C stdlib function

The C standard library is a collection of functions that are included in every C compiler. These functions perform input/output, memory allocation, string manipulation, and more. stdlib is an essential part of the C language and learning how to use it can make your life as a programmer much easier. Here are five stdlib functions that you didn’t know you needed.

2)C++ 11 core library function

The C++ standard library provides a set of common classes and interfaces that greatly extend the core C++ language. The library, however, is not part of the language itself. As such, it’s easy to forget about the helpful functions it provides. Here are 5 that you didn’t know you needed.

3)Standard Template Library (STL) in C++

The Standard Template Library (STL) is a collection of algorithms and data structures that are essential for many software development projects. The STL includes the following:
-vector: A vector is a data structure that stores a sequence of elements.
-map: A map is a data structure that stores key-value pairs.
-set: A set is a data structure that stores a collection of unique elements.

4)Boost Libraries

The Boost libraries are a set of peer-reviewed portable C++ source libraries. There are over eighty Boost libraries available. These libraries range from low-level functions such as smart pointers and multithreading, to high-level functions such as image processing and machine learning. In this blog post, we will focus on the five best Boost libraries that you may not know you needed.

5)Template Metaprogramming

C++ template metaprogramming is a powerful technique that allows you to write code that is expressive, clean, and easy to maintain. It is a form of metaprogramming that enables you to write code that is executed at compile time, rather than run time. This can be used to great effect to optimize your code and make it more efficient. Here are 5 C++ template metaprogramming functions that you didn’t know you needed.
