C is pass by value (or call by value). If you want a function
call to be able to change something, you pass a pointer to
the something.

But also you often (usually) pass a pointer when you are 
passing an array or structure. Before ANSI C, you couldn't pass
structures directly, only through pointers. ANSI allows it, but
it isn't used all that often.
