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:

 1 #include <stdio.h>

 2 

 3 int main()

 4 {

 5     int a,b;

 6     

 7     scanf("%d %d", &a, &b);

 8     printf("%d + %d = %d\n", a, b, a+b);

 9     printf("%d - %d = %d\n", a, b, a-b);

10     printf("%d * %d = %d\n", a, b, a*b);

11     printf("%d / %d = %d\n", a, b, a/b);

12         

13     return 0;

14 }

 Java代码实现:

 1 import java.util.Scanner;

 2 

 3 public class Main {

 4     public static void main(String[] args) {

 5         int a, b;

 6         Scanner s1 = new Scanner(System.in);

 7         a = s1.nextInt();

 8         b = s1.nextInt();

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

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

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

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

13     }

14 }
