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 ", a, b, a+b); 9 printf("%d - %d = %d ", a, b, a-b); 10 printf("%d * %d = %d ", a, b, a*b); 11 printf("%d / %d = %d ", 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 }
