It is basically a header file that also includes every standard library and stl include file. So if we #include bits/stdc++.h in a C++ program then there is no need to include any other header files. bits/stdc++.h is not a standard header file of GNU C++ library. So, if you try to compile your code with some compiler other than GCC it might fail. Using it would include a lot of unnecessary stuff and increases compilation time. This header file is not part of the C++ standard, is therefore non-portable, and should be avoided. Below is Linux GCC 4.8.0 /bits/stdc++.h header definition. (Some syntax lost due to formatting ) /** @file stdc++.h // C++ #include algorithm #include bitset #include complex #include deque #include exception #include fstream #include functional #include iomanip #include ios #include iosfwd #include iostream #include istream #include iterator #include limits #include list #include locale #include map #include memory #include new #include numeric #include ostream #include queue #include set #include sstream #include stack #include stdexcept #include streambuf #include string #include typeinfo #include utility #include valarray #include vector read less
