c - Uses of static variables inside functions -

-

i have been writing c code many years, came accross feature have never used: static variable inside function. therefore, wondering ways have used feature , right design decision.

e.g.

int count(){     static int n;     n = n + 1;     return n; }

is bad design decision. why? because later might want decrement count involve changing function parameters, changing calling code, ...

hopefully clear enough, thanks!

void first_call() {    static int n = 0;     if(!n) {      /* stuff here on first call */      n++;    }     /* other stuff here */ }
