Q3-1
Enter a year, and it will tell you whether the Olympics will be held in that year or not.
Create a program that displays
If possible, it would be better if it could distinguish between summer and winter.
Hint: The Sydney Olympics (summer) were held in 2000.
The conditions are complicated, so please use the following
Ignore the previous years when the summer and winter seasons were in the same year.

Program reading (example solution)
Solution 2-1
Indicate whether the input value is odd or even.
O stands for odd and E for even.
The % calculates the remainder.
The last printf function is only for line breaking.
Program writing (example of solution)
Solution 3-1
#include <stdio.h>
int main(void)
{
int year;
printf("Please enter year of year:");
scanf("%d", &year);
if (year % 4 == 0) printf("Summer Olympics\n");
if (year % 2 == 0 && year % 4 ! = 0) printf("Winter Olympics\n");
if (year % 2 ! = 0) printf("No Olympics\n"); if (year % 2 == 0 && year % 4 !
return 0;
}*Here, the year the Olympics are held is divisible by two.
In addition, we took advantage of the fact that it is also divisible by 4 during the Summer Olympics.
*Other calculation methods are possible, so the answer is correct if it is obtained by calculation.
*If the years are compared as they are without calculation, the answer is incorrect.
