#184023 - Another static question... |
I've been meanng to ask this for a while now.
Page 113 of K&R second edition gives the following example code.
/* month_name: return name of n-th month */
char *month_name(int n)
{
static char *name[] = {
"Illegal month",
"January", "February", "March",
"April", "May", "June",
"July", "August", "September",
"October", "November", "December"
};
return (n < 1 || n > 12) ? name[0] : name[n];
}
What I don't understand is why char *name is declared static. I (think) I understand the static keyword. It restricts scope to the current procedure, and it provides permanent storage within a function. Neither appears to be a requirement in this example, or am I missing something? |

| Thank you | 01/01/70 00:00 | |
| It is worse than that | 01/01/70 00:00 | |
| could add 'const' | 01/01/70 00:00 | |
| That's the key! | 01/01/70 00:00 | |
| Thanks Neil | 01/01/70 00:00 | |
| True - but not quite the point here | 01/01/70 00:00 | |
| isn't it explained in the book itself? | 01/01/70 00:00 | |
| Yes, it is | 01/01/70 00:00 | |
| Yes, but... | 01/01/70 00:00 | |
| If the pupil does not understand... | 01/01/70 00:00 | |
| In this instance... | 01/01/70 00:00 | |
That is why the call it learning. | 01/01/70 00:00 | |
| isn't this just another example of .... | 01/01/70 00:00 | |
