1 cout << "enter two numbers:" << endl;
2     int v1 = 0, v2 = 0;
3     cin >> v1 >> v2;
4     cout << "the sum of " <<  v1  << " and " << v2 << " is " << v1 + v2 << endl;
#  the sum of 4 and 6 is 10
#输出变量v1，v2两边加空格，这样控制台输出结果才好看
#空格和回车 输入多个数

 1 while (cin>>value) 2 { 3 sum += value; 4 } 输入任意字母，退出循环，控制台得出结果

 

这里只统计最后连续输出的值    

int  v = 0,a,cnt;
    while (cin>>a)
    {
        if (a == v)
        {
            ++cnt;
        }
        else
        {
            cnt = 1;
            v = a;
        }
    }
    cout << v << " 出现了 " << cnt << " 次 " << endl;
