[코드업 기초 100제] Java 1041 ~1045 풀이

1041 : [기초-산술연산] 문자 1개 입력받아 다음 문자 출력하기

import java.util.*;

public class Main {
	public static void main(String arg[]){
		
		Scanner sc = new Scanner(System.in);
		
		char a = sc.next().charAt(0);
		
		System.out.println((char)(a + 1));
		
	}
}

1042 : [기초-산술연산] 정수 2개 입력받아 나눈 몫 출력하기

import java.io.*;
import java.util.*;

public class Main {
	public static void main(String arg[]) throws IOException{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		
		String s = br.readLine();
		
		StringTokenizer st = new StringTokenizer(s, " ");
		
		int a = Integer.parseInt(st.nextToken());
		int b = Integer.parseInt(st.nextToken());
		
		System.out.println(a / b);
	}
}

1043 : [기초-산술연산] 정수 2개 입력받아 나눈 나머지 출력하기

import java.util.*;
import java.io.*;

public class Main {
    public static void main(String arg[]) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        StringTokenizer st = new StringTokenizer(br.readLine());

        int a = Integer.parseInt(st.nextToken());
        int b = Integer.parseInt(st.nextToken());

        System.out.println(a % b);
    }
}

1044 : [기초-산술연산] 정수 1개 입력받아 1 더해 출력하기

import java.util.*;
import java.io.*;

public class Main {
    public static void main(String arg[]) throws IOException {
        Scanner sc = new Scanner(System.in);
        
        Long l = sc.nextLong();
        System.out.println(++l);
    }
}

1045 : [기초-산술연산] 정수 2개 입력받아 자동 계산하기

import java.util.*;

public class Main {
    public static void main(String arg[]) {
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();
        
        System.out.println(a + b);
        System.out.println(a - b);
        System.out.println(a * b);
        System.out.println(a / b);
        System.out.println(a % b);
        System.out.printf("%.2f", (float)a / b);
    }
}
