Write and run a quick C program

This should work on any unix platform running bash. Just type the program into cat and give it a ^D when you're done, at which time it will compile, run, and remove the program. Obviously, you can run it without the "rm a.out" if you'd like to keep the binary. If you want to keep the source, well, you might as well just write it in vi or emacs first then.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
alias cstdin='echo "Ctrl-D when done." && gcc -Wall -o ~/.stdin.exe ~/.stdin.c && ~/.stdin.exe'

This is a quick hack to make a gcc caller. Since it runs with gcc instead of tcc, it's a bit more trustworthy as far as the final answers of things go.

Know a better way?

If you can do better, submit your command here.

tcc -run code.c

tcc means tinyCC

gcc > tcc

What does bash have to do with it? It will work on any system that has gcc installed.

Useless use of cat award! The command will identically compile & run your code from stdin even without piping from cat.
