C headers conformance-CodePudding

I'm looking for a list of C standard library headers conformance report - as in, which headers are optional, which are mandatory for conforming compilers - for all C standards (or C20 at least).

CodePudding user response：

cppreference.com will give you all standards for C89 to C23 and C 98 to C 23. There is no C20 standard though, C17 was the last and C23 is the next.

CodePudding user response：

If you are using C language then please visit header-file-list-functions-c-language

here you will get all C standard library headers with proper definition with proper example.

and if you want to use all in one library then save your file .cpp example test.cpp and type in header:

#include<bits/stdc  .h>
using namespace std;
int main()
{ 
   //write your code here c or c   what ever you want. both will work
}
