通过使用两个int变量浮点到int转换来表示float变量 [英] Float to int conversion by using two int variables for representation of the float variable
问题描述
各位大家好，我想请任何人帮我理解
应该完全解决这个问题。到目前为止，我已经提供了我所拥有的
，虽然它不太准确。
创建一个以美元操作的类。调用新类Money。
此类中所有数据组件的美元和美分都是整数
变量（这是我感到困惑的地方，不知道如何实际上
做的工作）。包括成员函数和构造函数以初始化
Money为0并将其初始化为固定值。会员功能
应以适当的格式显示。包括
允许双向数据转换的成员函数：
- 从实际（浮动）价值（4.5f美元）到美元/美分（4美元，50美元） $>
美分）
- 从美元/美分（4美元，50美分）到实际（浮动）价值（4.5f
美元）
这是我到目前为止所做的事情虽然我不确定
如果我的方法是正确的话。所以，如果有人可以帮我这个，我会很感激，这很有意思，但我一直在尝试
很长一段时间我只能''弄明白！
感谢提前任何人！

class Money {
private：int dollars; int cents;
public：Money（）{dollars = 0;美分= 0; } $ / $
Money（int dol，int cnt）{dollar = dol;美分= cnt; } $ / $
Money（float fl_dollars）// one-arg构造函数
{
cout<< fl_dollars值是： << fl_dollars<< endl;
float flt_dollars = fl_dollars;
dollar = int（flt_dollars）;
cout<< fl_dollars值是： << flt_dollars<< endl<< "并且
美元是： << levs<< endl;
float cents_part = float（fl_dollars - dollar）;
cents = cents_part;
cout<< 转换后的分数： <<美分<< endl;
cout<< 美分值是： <<美分<< endl;
cout<< \ n 1-arg构造函数已激活\ n;

Hello everybody, I would like to ask anybody to help me understand what
should be done exactly with this Problem. I have provided what I have
up to now, although it is not quite accurate.
Create a class to operate on the US currency. Call the new class Money.
All the data components in this class for dollars and cents are integer
variables (this is where I get confused and don''t know how to actually
do the job). Include member functions and constructors to initialize
Money to 0 and to initialize it to fixed values. A member function
should display it in appropriate format. Include member functions that
permit data conversion in both directions:
- from real (float) value (4.5f US) to dollars/cents ( 4 dollar, 50
cents)
- from dollars/cents (4 dollar, 50 cents) to real (float) value (4.5f
US)
Here it is what I have managed to do up to now although I am not sure
if I am on the right way even. So if anybody could help me with this I
would really appreciate, it is interesting, but I''ve been trying for
quite some time and I just can''t figure it out!
Thanks to anyone in advance!
#include <iostream>
using namespace std;
class Money {
private: int dollars; int cents;
public: Money() { dollars = 0; cents = 0; }
Money (int dol, int cnt) { dollars = dol; cents = cnt; }
Money (float fl_dollars) // one-arg constructor
{
cout << "fl_dollars value is: " << fl_dollars << endl;
float flt_dollars = fl_dollars;
dollars = int(flt_dollars);
cout << "fl_dollars value is: " << flt_dollars << endl << " And
dollars are: " << levs << endl;
float cents_part = float(fl_dollars - dollars);
cents = cents_part;
cout << "Cents after conversion: " << cents << endl;
cout << "cents value is: " << cents<< endl;
cout << "\n 1-arg Constructor activated\n";
}
void ShowMoney()
{
cout <<"\nDistObject= " << dollars << " dollars" <<" and "<< cents
<< " cents" << endl << endl;
}
};
void main ()
{
// Conversion from Basic to User Defined >>> one-arg Constructor
Money d3 = 10.89;
d3.ShowMoney();
}

[...]
class Money {
私人：美元; int cents;
public：Money（）{dollars = 0;美分= 0; Money（int dol，int cnt）{dollar = dol;美分= cnt; Money（float fl_dollars）//一个arg构造函数

float flt_dollars = fl_dollars;
dollar = int（flt_dollars）;

我猜这里''levs''应该是''美元''这里......
float cents_part = float（fl_dollars - dollar）;
美分=美分_部分;
如果''cents_part''是0.89（美元金额的一小部分），那多少美元是多少美分？你是怎么得到那个答案的？
cout<< 转换后的分数： <<美分<< endl;
cout<< 美分值是： <<美分<< endl;
cout<< " \\\
1-arg构造函数已激活\ n";
}
void ShowMoney（）
{
cout<<" \ nDistObject =" <<美元<< "美元" <<"和<<分
<< "美分" << endl<< endl;
}
};
void main（）
{
//从基本转换为用户定义>>> one-arg构造函数
钱d3 = 10.89;
d3.ShowMoney（）;

[..]
class Money {
private: int dollars; int cents;
public: Money() { dollars = 0; cents = 0; }
Money (int dol, int cnt) { dollars = dol; cents = cnt; }
Money (float fl_dollars) // one-arg constructor
{
cout << "fl_dollars value is: " << fl_dollars << endl;
float flt_dollars = fl_dollars;
dollars = int(flt_dollars);
cout << "fl_dollars value is: " << flt_dollars << endl << " And
dollars are: " << levs << endl;
I am guessing ''levs'' should be ''dollars'' here...
float cents_part = float(fl_dollars - dollars);
cents = cents_part;
If ''cents_part'' is 0.89 (the fraction of the dollar amount), how many
full cents is it? How did you get that answer?
cout << "Cents after conversion: " << cents << endl;
cout << "cents value is: " << cents<< endl;
cout << "\n 1-arg Constructor activated\n";
}
void ShowMoney()
{
cout <<"\nDistObject= " << dollars << " dollars" <<" and "<< cents
<< " cents" << endl << endl;
}
};
void main ()
{
// Conversion from Basic to User Defined >>> one-arg Constructor
Money d3 = 10.89;
d3.ShowMoney();
}

是的我的坏它应该是美元而不是levs，我已经忘了用美元来改变它。
yes my bad it should have been dollars instead of levs, i have
forgotten to change it with dollars.
