visual studio 的汇编c++写一个判断用户输入数据的程序，已附图

Question

检测正数负数和0各自的数量。
•询问用户想输入多少个数字
•循环给定次数
•提示用户每次循环输入一个数字
•显示有多少正数，负数和零数被输入的摘要
汇编代码将在C程序的_asm块中，使用C语言声明变量
语法，如实验室任务中所示。从现有的模板创建一个新的Visual Studio项目。的
下面的屏幕截图显示了程序的预期输出。

Answer 1

#include <iostream>

using namespace std;

int main()
{
    int n,tmp;
    cout << "How many numbers:";
    cin >> n;
    int pos = 0, neg = 0, zero = 0;
    for (int i = 0; i < n; i++)
    {
        cout << "Enter a number:";
        cin >> tmp;
        if (tmp==0)
        {
            zero++;
        }
        if (tmp>0)
        {
            pos++;
        }
        if (tmp<0)
        {
            neg++;
        }
    }
    cout << "----------\n";
    cout << "Positive:" << pos << "\n";
    cout << "Negtive:" << neg << "\n";
    cout << "Zero:" << zero << "\n";
}
