Q3-1
Create a program that displays whether or not the Olympics will be held when the year of the year is entered.
However, the part that calculates the Olympic Games should be created as a separate function.
The summer games will be held in the year 2000, and every two years thereafter, in the order of winter->summer->winter->summer.
Also, this schedule is assumed to be eternally consistent.

Solution 3-1
#include <stdio.h>
int olympic(int year);
int main(void)
{
int year, hold;
scanf("%d", &year);
hold = olympic(year);
switch (hold) {
case 0:
printf("not opened\n");
break;
case 1:
printf("Summer Olympics\n");
break;
case 2:
printf("Winter Olympics\n");
break;
};
return 0;
}
int olympic(int year)
{
if (year % 2 == 0) {
if (year % 4 == 0) {
return 1;
} else {
return 2;
}
} else {
return 0;
}
}The return value of the *olympic function is mapped to the holding.
*Note that it is easy to forget the prototype declaration.
