Assign ints before main(){}

This is a combination of 2 golfing tricks. It's possible to write a program as just main(){}, though it will send a warning, not an error though, so it's still safe to run.

A cool trick with using this is assigning values meant to be ints which you can assign inside main anyway.

Try changing the number value here, it works!

i;main(){i=0;printf("%i",i);}

Try it online!

No need for i=0. (1 comment)
No need for i=0.

In case of the value zero specifically, i is guaranteed to already be zero even in strictly conforming C, since it has static storage duration. So maybe use some other number for example :)
