How do I run a C program from VIM?

Question

Is there a way to compile and run a C program from VIM without typing its filename ?

Answer 1

:!gcc -o somename % && ./somename
When using :!, % will be substituted by the name of the currently opened file.

When your project becomes larger, you can also write a makefile and compile the current project with :make, if there are any errors, vim will jump to them automatically.
