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; case 2:if (min != 12) minu2 = " two"; else minu2 = " twelve"; break; case 3:if (min != 13) minu2 = " three"; else minu2 = " thirteen"; break; case 4:if (min != 14) minu2 = " four"; else minu2 = " fourteen"; break; case 5:if (min != 15) minu2 = " five"; else minu2 = " fifteen"; break; case 6:if (min != 16) minu2 = " six"; else minu2 = " sixteen"; break; case 7:if (min != 17) minu2 = " seven"; else minu2 = " seventeen"; break; case 8:if (min != 18) minu2 = " eight"; else minu2 = " eighteen"; break; case 9:if (min != 19) minu2 = " nine"; else minu2 = " nineteen"; break; case 0: minu2 = ""; break; } int c; c = min /10; switch (c) { case 0:minu1 = ""; break; case 1:minu1 = ""; break; case 2:minu1 == " twenty"; break; case 3:minu1 == " thirty"; break; case 4:minu1 == " forty"; break; case 5:minu1 == " fifty"; break; case 6:minu1 == " sixty"; break; default:cout << "error time"; } return 0; } 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"); }

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";
}
供参考。

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"); }
