How many functions are there in std in c++

As of C 23, there are about 2000 functions in the standard library. These functions are distributed in different header files, such as <algorithm> for algorithms, <string> for string processing, <vector> for containers, <iostream> for input/output,

Number of functions in std in C

C The standard library (std) contains a large number of functions for performing various kind of task. In fact, the number of functions included in the standard library is constantly changing and varies depending on the specific implementation of C.

As of C 23, there are approximately 2000 functions in the standard library. These functions are distributed in different header files, for example:

• <algorithm>: algorithm
• <string>: String processing
• <vector>: container
• <iostream>: input/output
• <chrono>: Time and date

Using functions in the std library can greatly improve the efficiency and readability of C code. For example, you can use the functions in the <vector> header file to manage dynamically sized arrays, or use the functions in the <algorithm> header file to sort a container and search.

It is worth noting that the C standard library is constantly being updated and expanded, which means that more functions may be added in the future.
