所以我几乎完成了这个非常简单的程序,但我的代码有三个问题。
首先是我无法想出显示双零。
秒(这也可以追溯到第一个问题)输入类似0001的内容,而不是上午12:01,我得到0:1 am。
第三是我如何找到平均值?我想添加用户输入的每个军事时间(当我第一次解决前两个问题时会这样做),除以他们输入的输入数量,然后将该平均值恢复为HH:MM格式。
第四(可选但建议) - 请查看代码,看看是否可以找到我找不到的任何其他逻辑错误。请记住,一双新的眼睛更容易发现错误。
以下是控制台窗口的示例输出。
Welcome to my military time converter.
Please enter the hour hand. 12
Now enter the minute hand. 00
Please wait a second. I'm converting it to the correct format.
Press any button to continue.
Done
The time right now is 12:0Pm.
Process returned 0 (0x0) execution time : 7.774 s
Press any key to continue.
这是我的代码
#include <iostream>
using namespace std;
class Time
{
private:
int hour;
int minute;
public:
void setTime(int &x, int &y)
{
while((x > 24) || (y > 60))
{
cerr << "\nError, that isn't in standard format. " << endl;
cin >> x;
cin >> y;
}
if(x <= 12)
{
hour = x;
}
else
hour = x-12;
minute = y;
}
int getHour()
{
return hour;
}
int getMinute()
{
return minute;
}
void printTime()
{
cout << "\nThe time right now is ";
cout << getHour() << ":" << getMinute();
}
string timeOfDay(int &x, int &y)
{
const string timeArray[2]={"Am", "Pm"};
string noon={" Noon"};
string midnight={" Midnight"};
if(x < 12)
{
return timeArray[0];
}
else if(x == 12 && y == 0 )
{
return noon;
}
else if( x == 24 && y == 0)
{
return midnight;
}
else
return timeArray[1];
}
};
int main()
{
Time t;
int h;
int m;
cout << "Welcome to my military time converter. " << endl;
cout << "\nPlease enter the hour hand. ";
cin >> h;
cout << endl;
cout << "Now enter the minute hand. ";
cin >> m;
cout << endl;
t.setTime(h, m);
cout << "Please wait a second. I'm converting it to the correct ";
cout << "format. " << endl;
cout << "\nPress any button to continue. " << endl;
cin.ignore();
cin.get();
cout << "Done " << endl;
t.printTime();
cout << t.timeOfDay(h, m) << endl;
return 0;
}

<pre>
// TEST with convertToClockTime(0930)
// if you give 09:65 it returns you 10:05
// you can use this to add minutes if you need
int convertToClockTime(int number) {
stringstream strStream;
strStream << number;
string orgString = strStream.str();
int length = orgString.length();
string minuteStr = "", hourStr = "";
if (length == 4) {
hourStr = orgString.substr(0, 2);//orgString[0];
minuteStr = orgString.substr(2, 2);//orgString[1] + orgString[2];
}
else if (length == 3) {
hourStr = orgString.substr(0, 1);//orgString[0];
minuteStr = orgString.substr(1, 2);//orgString[1] + orgString[2];
}
int minute = 0, hour = 0;
strStream.str("");
strStream.clear(); // Clear state flags.

要在输出中格式化为双倍,请使用以下命令:
cout << setfill('0') << setw(2) << getHour;
根据需要进行调整以添加分钟数。
要获得平均时间,我会将军事价值转换为秒,然后将秒数转换为12小时制。
答案 2 :(得分:0)
将您的数字转换为字符串并输出字符串而不是数字(例如.. if(y&lt; 10){string =“0”+ toString(x);}
当x小于12时,您将小时设置为x。00小于12,因此结果将为0.
以数分钟(x * y)存储在数组中输入的时间。除以次数。转换回小时和分钟(小时=总分钟/ 60,分钟=总分钟%60)。
