코드업 100제(1066~1070)

1066 .세 정수 a, b, c가 입력되었을 때, 짝(even)/홀(odd)을 출력해보자.

 

import java.util.Scanner;

public class main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int x=sc.nextInt();
		int y=sc.nextInt();
		int z=sc.nextInt();
	
		holjjak(x);
		holjjak(y);
		holjjak(z);
	}

      public static void holjjak(int num) {
		if(num%2==0)
			System.out.println("짝");
		else
			System.out.println("홀");
		
	}
	}

 

 

 

 

 

 

1067. 정수 1개가 입력되었을 때, 음(minus)/양(plus)과 짝(even)/홀(odd)을 출력해보자.

 

import java.util.Scanner;

public class main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int x=sc.nextInt();
		int y=sc.nextInt();
		int z=sc.nextInt();
	
		holjjak(x);
		holjjak(y);
		holjjak(z);
	}

      public static void holjjak(int num) {
		if(num%2==0)
			System.out.println("짝");
		else if(num<0)
			System.out.println("음수");
		else
			System.out.println("홀");
	}}

 

 

 

 

 

1068. 점수(정수, 0 ~ 100)를 입력받아 평가를 출력해보자.

 

import java.util.Scanner;

public class main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int x=sc.nextInt();

		if(x>=90) 
			System.out.println("A");
		else if(x>=70 && x<=89)
			System.out.println("B");
		else if(x>=40 && x<=69)
			System.out.println("C");
		else
			System.out.println("D");
	}}

 

 

 

 

 

1069. 평가를 문자(A, B, C, D, ...)로 입력받아 내용을 다르게 출력해보자.

 

import java.util.Scanner;

public class main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		String x=sc.next();
		
		String big=x.toUpperCase();
		
		switch(big) {
		case "A" :
			System.out.println("best!!!");
			break;
		case "B" :
			System.out.println("good!!");
			break;
		case "C" :
			System.out.println("run!");
			break;
		case "D" :
			System.out.println("slowly~");
			break;
		default:
			System.out.println("what?");
		}	
	}}

 

 

 

 

 

1070. 월이 입력될 때 계절 이름이 출력되도록 해보자.

 

import java.util.Scanner;

public class main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int x=sc.nextInt();
		
		if (x>=13 || x<0)
			System.out.println("제대로된 숫자 입력");
		switch(x) {
		case 12:
		case 1:
		case 2:
			System.out.println("winter");
			break;
		case 3:
		case 4:
		case 5:
			System.out.println("spring");
			break;
		case 6:
		case 7:
		case 8:
			System.out.println("summer");
			break;
		case 9:
		case 10:
		case 11:
			System.out.println("fall");
			break;
		}	
	}}
