找不到标识符这是为什么呢？

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
char*date[7] = { "Sunday", "Monday", " Tuesday ", "Wednesday", "Thursday", "Friday", "Saturday" };
int func（int）;
int main()
{
int n;
int adress;
printf("Date:");
scanf_s("%d", &n);
n++;
func(n);
printf("It is %s(%d)\n", date[n], date[n]);
system("PAUSE");
return 0;
}
int func(int i)
{
int num = *date[i];
printf("%d", num);
return 0;
}
