Question

我用Dev C ++开发了具有getter和setter以及构造函数的C ++应用程序。我通过构造函数发送日，小时，分钟，秒变量，并希望将其打印出来。

但是在运行和编译时出现错误，例如“未编译源文件”。

如何解决此问题？我已经删除了collect2.exe文件，但问题仍然存在。

Sinif.CPP

#include "Sinif.h"
#include <iostream>
#include <iomanip>
using namespace std;

Sinif::Sinif(int d,int h, int m, int s) {
   day=d;
   hour = h;
   minute = m;
   second = s;

}
int Sinif::getDay() const {
   return day;
}
 void Sinif::setDay(int d) {
   day = d;
}
int Sinif::getHour() const {
   return hour;
}
 void Sinif::setHour(int h) {
   hour = h;
}
 int Sinif::getMinute() const {
   return minute;
}
 void Sinif::setMinute(int m) {
   minute = m;
}
int Sinif::getSecond() const {
   return second;
}
 void Sinif::setSecond(int s) {
   second = s;
}
 void Time::setTime(int d,int h, int m, int s) {
   day=d;
   hour = h;
   minute = m;
   second = s;
}
 void Time::print() const {
   cout << setfill('0');   
   cout << setw(2) << day 
   cout <<":"<< setw(2) << hour  
        << ":" << setw(2) << minute
        << ":" << setw(2) << second << endl;
}

Sinif.h

#ifndef TIME_H 
#define TIME_H   
class Sinif {
private:  
   int day;
   int hour;     
   int minute;   
   int second;  
public: 

   Sinif(int d=0,int h = 0, int m = 0, int s = 0); 
   int getDay() const;   // public getter for private data member hour
   void setDay(int d);
   int getHour() const;   // public getter for private data member hour
   void setHour(int h);   // public setter for private data member hour
   int getMinute() const; // public getter for private data member minute
   void setMinute(int m); // public setter for private data member minute
   int getSecond() const; // public getter for private data member second
   void setSecond(int s); // public setter for private data member second
   void setTime(int d,int h, int m, int s);   // set hour, minute and second
   void print() const; // Print a description of this instance in "hh:mm:ss"
};  // need to terminate the class declaration with a semicolon

#endif  // end of "#ifndef" block

主CPP

#include <iostream>
#include "Sinif.h" 
using namespace std;
int main() {
   Sinif t1(25,23, 59, 59);   // Test constructor
   // Test all public member functions
   t1.print(); 
   t1.setDay(17);
   t1.setHour(12);
   t1.setMinute(30);
   t1.setSecond(15);
   t1.print();       // 12:30:15
   cout << "Day is "    << t1.getDay()    << endl;
   cout << "Hour is "   << t1.getHour()   << endl;
   cout << "Minute is " << t1.getMinute() << endl;
   cout << "Second is " << t1.getSecond() << endl;

   Sinif t2;     // Test constructor with default values for hour, minute and second
   t2.print();  // 00:00:00
   t2.setTime(10,1, 2, 3);
   t2.print();  // 01:02:03

   Sinif t3(12); // Use default values for minute and second
   t3.print();  // 12:00:00

}

您应该做什么

阅读完整的构建输出，它将告诉您哪里出了问题以及在哪里。

在这种情况下，这可能是由于以下原因造成的：

<div class="pdf-container ">
    <div class="canvas-container">
        {{#if pageIsRendering}}
          <div class="loader">
            {{loading-spinner isLoading="true"}}
          </div>
        {{/if}}
    </div>
</div>

（您的课程称为void Time::setTime(int d,int h, int m, int s) { day=d; hour = h; minute = m; second = s; }，而不是Sinif。）

…还有这个

Time

（无终止分号。）

修正了这些问题后，your program compiles and runs（看起来像预期的输出）。

你不应该做的事

删除GCC的一部分，例如cout << setw(2) << day。您可能现在必须重新安装工具链。

Dev C ++源文件未编译
