C++ 添加错误、简单问题

菜鸟问题！当我运行这个，我把客人的数量设为2，我应该有2个小比萨饼，因为这个数字不大于3（使之成为中等），当我运行它时，它告诉我所有尺寸的0。舍入误差？我该如何解决这个问题--请说英语，我是初学者：）

使用名称空间std；
int main（）
{
//提示用户
cout>与会者；
int large_pizzas=与会者/7；
cout也许你可以调整你想要的方式：

#include <iostream>

#define LARGE_PIZZA_SHARE 7     // 7 persons can share 1 large pizza
#define MEDIUM_PIZZA_SHARE 3    // 3 persons can share 1 medium pizza
#define SMALL_PIZZA_SHARE 1     // 1 person - 1 small pizza

int main()
{
    int attendees = 0;
    cout << "Enter number of attendees: ";
    cin >> attendees;

    int largePizzaCount = 0;
    int mediumPizzaCount = 0;
    int smallPizzaCount = 0;

    if (attendees >= LARGE_PIZZA_SHARE)
    {
        largePizzaCount = attendees / LARGE_PIZZA_SHARE;
        attendees = attendees % LARGE_PIZZA_SHARE; 
    }

    if (attendees >= MEDIUM_PIZZA_SHARE)
    {
        mediumPizzaCount = attendees / MEDIUM_PIZZA_SHARE;
        attendees = attendees % MEDIUM_PIZZA_SHARE;
    }

    if (attendees >= SMALL_PIZZA_SHARE)
    {
        smallPizzaCount = attendees / SMALL_PIZZA_SHARE;
    }

    cout << "You require: " << largePizzaCount << " large pizzas, " << mediumPizzaCount << " medium pizzas, and " << smallPizzaCount << " small pizzas!" << endl;

    return 0;
}

#定义大比萨饼共享7//7人可以共享1个大比萨饼
#定义中号比萨\u共享3//3人可以共享1个中号比萨
#定义小比萨饼分享1//1人-1个小比萨饼
int main（）
{
int与会者=0；
cout>与会者；
int largepizzaccount=0；
int mediumPizzaCount=0；
int smallpizzaccount=0；
如果（与会者>=大比萨饼分享）
{
LargePizzaccount=与会者/大比萨份额；
与会者=与会者%LARGE\u PIZZA\u份额；
}
如果（与会者>=中等比例）
{
Mediumpizzaccount=与会者/中等比萨饼份额；
与会者=与会者%中等份额；
}
如果（与会者>=小型比萨饼分享）
{
Smallpizzaccount=与会者/小比萨饼份额；
}
不能在调试器中单步执行。想想
%1
的意思。你太棒了！
