蓝桥杯算法提高- c++_ch02_02-题解（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 main(String[] args) {

Scanner scanner = new Scanner(System.in);

int a=scanner.nextInt();

int b=scanner.nextInt();

char c=scanner.next().charAt(0);//转换成字符

switch (c) 

{

case '+':

System.out.println(a+b+" ");

break;

case '-':

System.out.println(a-b+" ");

break;

case '*':

System.out.println(a*b+" ");

break;

case '/':

System.out.println(a/b+" ");

break;

case '%':

System.out.println(a%b+" ");

break;

}

}

}
