代码刚刚写的, 你看下 include(stdio.h)main(){ printf("shu ru shu zi:\n");int i,j,s;scanf("%d,%d",&i,&j);s=i*j;printf("i*j=%d",s);}
printf("请输入一个整数或两个整数的乘积:\n");if(scanf("%d", &a) == 1) { // 如果输入了一个整数 printf("%d的平方是%d\n", a, a*a);} else if(scanf("%d%d", &a, &b) == 2) { // 如果输入了两个整数 product = a * b;printf("%d和%d的乘积是%d\n", a, b,...
C#程序源码：static void Main(string[] args){ Console.Write("a=");string a = Console.ReadLine();Console.Write("b=");string b = Console.ReadLine();double x = Convert.ToDouble(a);double y = Convert.ToDouble(b);Console.WriteLine("a+b=" + (x + y));Console.WriteLine("a...
include<stdio.h>void main(){ int a,b; scanf("%d%d",&a,&b); //输入两个数 printf("%d\n",a*b); //输出乘积} 如果要通过程序来保证测试数据大于-100，小于100，而不是输入的时候人为的控制，则可以加一个if判断，如果需要的话可以追问，我再详细说 ...
include <stdio.h> int main(){ int a,b;while(scanf("%d%d",&a,&b)==2){ printf("%d+%d%c%d*%d\n",a,b,(a+b>a*b?'>':a+b==a*b?'=':'<'),a,b);} return 0;} 请点击输入图片描述
