求C++源代码小学算数题目

[j4nker]

1. 加减 （乘除可以自己选）

2.题目随机、数量随机。

3.给出错误提示。答对给鼓鼓励。


求源代码、编译

[梦境传说]

lz:这是的作业题目吗？

[Love_云]

这作业题目简单啊

要求不多

自己发挥呗

#include <iostream>
#include <time.h>
using namespace std;

int main(int argc, char** argv)
{
	int a;
	int b;
	int result;
	int value;

	srand((unsigned)time(NULL));

	cout << "请计算如下算式(输入-1退出)：" << endl;
	while(true)
	{
		a = rand();
		b = rand();

		if(a % 2 == 0)
		{
			cout << a << " + " << b << " = ";
			result = a + b;
		}
		else
		{
			if(a > b)
			{
				cout << a << " - " << b << " = ";
				result = a - b;
			}
			else
			{
				cout << b << " - " << a << " = ";
				result = b - a;
			}
		}

		cin >> value;

		if(-1 == value)
		{
			cout << "欢迎继续来练习..." << endl;
			break;
		}

		if(value == result)
		{
			cout << "正确！继续努力！" << endl;
		}
		else
		{
			cout << "错误！正确的答案是： " << result << endl;
		}
	}
	
	return 0;
}

要有个可视化界面就好了

[MayCarry]

不知道你具体表达什么 有个例子就好了
