Question

C++编程 输入数字转换成对应的时间

我的代码其中分钟十位输不出来 求大神看看哪里错了

#include<iostream>
#include<string>
using namespace std;
int trans(int hours, int min, string &day, string &ho, string &minu1, string&minu2)
{
int a;
a = hours % 12;
switch (a)
{
case 0: if (hours == 0) day = "Midnight";
else day = "Noon";
ho = "";
break;
case 1: if (hours == 1) day = " AM";
else day = " PM";
ho = "One";
break;
case 2: if (hours == 2) day = " AM";
else day = " PM";
ho = "Two";
break;
case 3: if (hours == 3) day = " AM";
else day = " PM";
ho = "Three";
break;
case 4: if (hours == 4) day = " AM";
else day = " PM";
ho = "Four";
break;
case 5: if (hours == 5) day = " AM";
else day = " PM";
ho = "Five";
break;
case 6: if (hours == 6) day = " AM";
else day = " PM";
ho = "Six";
break;
case 7: if (hours == 7) day = " AM";
else day = " PM";
ho = "Seven";
break;
case 8: if (hours == 8) day = " AM";
else day = " PM";
ho = "Eight";
break;
case 9: if (hours == 9) day = " AM";
else day = " PM";
ho = "Nine";
break;
case 10: if (hours == 10) day = " AM";
else day = " PM";
ho = "Ten";
break;
case 11: if (hours == 11) day = " AM";
else day = " PM";
ho = "Eleven";
break;

}
int b;
b = min % 10;
switch (b)
{
case 1:if (min != 11) minu2 = " one";
else minu2 = " eleven";
break;

return 0;

cout << "Please input the time" << endl;
cin >> a >> b;
while (c)

cout << ho << minu1 << minu2 << day<<endl;

}

Answer 1

首先说，这代码写的太冗余了，最重要的是，你这代码里两个表示分钟的是什么意思啊

#include<iostream>
#include<string>
using namespace std;
void trans(int hours, int min, string &day, string &ho, string &minu1, string &minu2)
{
if(hours == 0) day = "Midnight";
else if(hours>12 ) day = " PM";
else day = " AM";
string num[]={"" ,"One", "Two" ,"Three", "Four", "Five","Six"," Seven","Eight" ,"Nine" , "Ten",
"Eleven", "Twelve", " Thirteen"," Fourteen"," Fifteen"," Sixteen"," Seventeen","Eighteen"," Nineteen",
"Twenty", " Thirty"," Forty"," Fifty"," Sixty"};
ho=num[hours];
if(min<20)
{
minu1="";
minu2=num[min];
}
else
{
minu1=num[min/10+18];
minu2=num[min%10];
}
}
void main()
{
int a, b,c; c = 1;
cout << "Please input the time" << endl;
cin >> a >> b;
while (c)
{
string day, ho, minu1, minu2;
trans(a, b, day, ho, minu1, minu2);
cout << ho << minu1 << minu2 << day<<endl;
cin >> a >> b;
}
system("pause");
}

追问

第一个是分钟的十位 第二个是分钟的个位啊~~~ 呵呵你有冗长的吗！？

追答

知道了 等下 马上好

Answer 2

调试了一下代码，这一段代码有问题：把赋值"="用成“==”了，赋值变成了比较导致分钟的十位没有值，把“==”改成“=“可解决这一问题。如下注释。
switch (c)
{
case 0:minu1 = "";
break;
case 1:minu1 = "";
break;
//case 2:minu1 == " twenty";
case 2:minu1 = " twenty";
break;
//case 3:minu1 == " thirty";
case 3:minu1 = " thirty";
break;
//case 4:minu1 == " forty";
case 4:minu1 = " forty";
break;
//case 5:minu1 == " fifty";
case 5:minu1 = " fifty";
break;
//case 6:minu1 == " sixty";
case 6:minu1 = " sixty";
break;
default:cout << "error time";
}
