解答

C语言版

#include <stdio.h>

int even(int n);

int main()
{
   
	int n;

	scanf("%d", &n);
	if (even(n))
		printf("%d is even.\n", n);
	else
		printf("%d is odd.\n", n);

	return 0;
}

int even(int n)
{
   
	return n % 2 == 0 ? 1 : 0;  // 偶数返回1，奇数返回0
}

C++版

#include<iostream>

int even(int n);

int main()
{
   
	int n;

	std::cin >> n;
	if (even(n))
		std::cout << n << " is even.\n";
	else
		std::cout << n << " is odd.\n";
	return 0;
}

int even(int n)
{
   
	return n % 2 == 0 ? 1 : 0;
}

Java版

public class Main{
   

	private static int even(int n) {
   
		return n % 2 == 0 ? 1 : 0;
	}
	public static void main(String[] args) {
   
		int n = 0;
		Scanner scanner = new Scanner(System.in);
		if(scanner.hasNext()) {
   
			n = scanner.nextInt();
		}
		scanner.close();
		if (even(n) == 1)
			System.out.println(n+" is even.");
		else
			System.out.println(n+" is odd.");
	}

}
