IO-02. 整数四则运算

本题要求编写程序，计算2个正整数的和、差、积、商并输出。题目保证输入和输出全部在整型范围内。

输入格式：

输入在一行中给出2个正整数A和B。

输出格式：

在4行中按照格式“A 运算符 B = 结果”顺序输出和、差、积、商。

输入样例：
3 2
输出样例：
3 + 2 = 5
3 - 2 = 1
3 * 2 = 6
3 / 2 = 1

C语言代码实现：

 #include <stdio.h>

 int main()
 {
     int a,b;

     scanf("%d %d", &a, &b);
     printf("%d + %d = %d\n", a, b, a+b);
     printf("%d - %d = %d\n", a, b, a-b);
     printf("%d * %d = %d\n", a, b, a*b);
     printf("%d / %d = %d\n", a, b, a/b);

     return ;
 }

Java代码实现：

 import java.util.Scanner;

 public class Main {
     public static void main(String[] args) {
         int a, b;
         Scanner s1 = new Scanner(System.in);
         a = s1.nextInt();
         b = s1.nextInt();
         System.out.println(a + " + " + b + " = " + (a + b));
         System.out.println(a + " - " + b + " = " + (a - b));
         System.out.println(a + " * " + b + " = " + (a * b));
         System.out.println(a + " / " + b + " = " + (a / b));
     }
 }
