Running Code Locally

If you're just starting out, it's easier to begin by running code online and worry about running locally later.

Using an IDE

Please let us know if you have trouble with installation!

Using Command Line

You can run your C++ programs from the command line and use a text editor of your choice.

Text Editors

Vim is probably the easiest way to print syntax-highlighted code on Mac, see the response to this post.

Sublime Text Notes (Ben)

• I prefer the Mariana color scheme in place of the default.
  • open command palette (Cmd-Shift-P) -> change color scheme
• subl symlink
  • Using /usr/local/bin/subl instead of ~/bin/subl worked for me on OS X Mojave.
• Package - Sublime Linter (GCC)
  • highlights compilation errors and warnings from -Wall
  • can change compilation commands in linter.py
• Package - Fast Olympic Coding (I don't use)
  • test manager can be useful
  • linting is covered by the above
  • stress testing is covered in Debugging
  • can't get debug to work

Further Instructions

See this module for information about installing, compiling, and running C++ from the command line.

Including <bits/stdc++.h>

You can use #include <bits/stdc++.h> in place of separately including libraries.

Usage

This is usable with GCC. However, Mac OS X uses Clang while Windows uses Microsoft Visual C++ (MVSC) by default. <bits/stdc++.h> is not a standard header file, so it will not work with the latter two. This is one of the reasons why you should not use <bits/stdc++.h> outside of competitive programming.

If you install GCC as described later in the module linked above, then you should be good to go.

OS-Specific Recommendations

Linux

Windows

Geany or CodeBlocks?

Mac

XCode?

Using <bits/stdc++.h> Without Installing GCC

If you installed Clang on Mac, then you can download stdc++.h from here and move it into a folder named bits that is located in the same directory as where all other C++ header files are located. However, this is not recommended.
