# <bits/stdc++.h> in MacOS

The `stdc++.h` file is just a file with a bunch of `include`. the only thing that you have to do is to put this file in the default location of the c++ import files. Here's a quick way to add it in MacOS.

#### With XCode installed

create a file named `stdc++.h` in this path:  (you should create `bits` folder first)

`/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/bits`

#### Without XCode

create a file named `stdc++.h` in this path:  (you should create `bits` folder first)

`/usr/local/include/bits`

Now, simply fill the created file with the content below:

```cpp

/** @file stdc++.h
 *  This is an implementation file for a precompiled header.
 */

// 17.4.1.2 Headers

// C
#ifndef _GLIBCXX_NO_ASSERT
#include <cassert>
#endif
#include <cctype>
#include <cerrno>
#include <cfloat>
#include <ciso646>

#include <cstdio>
#include <cstdlib>
#include <cstring>
#include <ctime>

#if __cplusplus >= 201103L
#include <ccomplex>
#include <cfenv>
```

or you can download the file and put it the right folder:

```bash
mkdir /usr/local/include/bits
curl https://gist.githubusercontent.com/devmarkpro/94d0b20a87bd0cc5f094a9b98336aa6d/raw/724c53e3210029f7bfd5dfa6254d124791547153/stdc++.h > /usr/local/include/bits/stdc++.h
```

NOTE: You have to repeat these steps each time that you update the `XCode Command-line Tools` so if you know a permanent solution for this problem, please share it in the comment section.
