C语言程序设计教程（第三版）课后习题11.1 （Java代码）

解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class Main {

        public static void S(int Y,int M,int D){

                int[] array = {31,28,31,30,31,30,31,31,30,31,30,31};

                int sum = 0;

               for(int i=0;i<M-1;i++)

                        sum +=array[i];

                        sum+=D;

                        if(Y%4==0&&Y%100!=0||Y%400==0)

                                if(M!=2)

                                sum+=1;

              System.out.print(sum);

        }

        public static void main(String[] arg){

                Scanner sc = new Scanner(System.in);

                int Y = sc.nextInt();

                int M = sc.nextInt();

                int D = sc.nextInt();

                S(Y, M, D);

        }

}
