C++ Built-in functions are the ready-made library functions. These are the part of the c++ programming language. C++ offers a large number of built-in library functions to solve programming problems faster and easier.
There are many libraries in c++ with have different sets of functions like iostream, cmath, ctime, etc. We don’t need to declare and define built-in functions. We directly use them anywhere in our code.
Here is the list of libraries that provide a variety of functions to perform different tasks in c++.
|Provide functions for general input and output
|This function library is used to solve mathematical problems
|This library provides a list of functions to deal with date and time
