# Assign `int`s 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 `int`s which you can assign inside `main` anyway.
- ## Try changing the number value here, it works!
- <!-- language-all: lang-c -->
- i;main(){i=0;printf("%i",i);}

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.
