 You can add aliases and functions here, such as the following to compile and run C++. 
 
 ```sh
-co() { g++ -std=c++14 -O3 -o $1 $1.cpp -Wall -Wextra -Wshadow -DLOCAL -Wl,-stack_size -Wl,0xF0000000; }

 run() { co $1 && ./$1 & fg; }

 # Flags
 -O3 tells g++ to compile your code to run as fast as possible.
--std=c++14 allows you to use features that were added to C++ in 2014.
+-std=c++17 allows you to use features that were added to C++ in 2014.
 -Wall -Wextra -Wshadow checks your program for common errors.
 
+You should always compile with these flags; define an alias (as explained above) so you don't need to type them every time!
