pointer to enum type
Can I pass a enumerate type pointer to a function?
I have never seen people pass enum type pointer to a function?
why???? is it unsafe data by passing that way???
enum Color {GREEN, YELLOW, RED};
void main(void)
{
enum Color colorVar = GREEN;
foo(&colorVar);
return;
}
void foo(enum Color *colorPtr)
{
*colorPtr = RED;
printf(" Traffic light now is RED");
}
>I have never seen people pass enum type pointer to a function?
Probably because there was no need for them to do so.
>is it unsafe data by passing that way???
Not at all.
>void main(void)
This, however, is unsafe. Use int main ( void ) and return 0;.
>void foo(enum Color *colorPtr)
Don't forget to declare a prototype or place the function definition before main.
And remember to include header files for the standard functions you intend to use, but I won't be too pedantic to you this time.
