C++ string problem

[hello1111]

Why I cant enter any input into the train.place1.from structure? when i compile no error occur.

struct date
{		int day;
		int month;
		int year;	
};

struct time
{		int hour;
		int minute;	
};

struct place
{		char from[20];
		char to[20];
};

struct detail
{		struct date dod;
		struct time time1;
		struct place place1;
		char cls,coach[3];
};

  void getdetail(char choice)
{
		cout<<"Please ENTER Train Detail "<<endl;
		cout<<"Departure date(day): ";
		cin>>train.dod.day;
		cout<<"Departure date(month): ";
		cin>>train.dod.month;
		cout<<"Departure date(year): ";
		cin>>train.dod.year;
		cout<<"Departure time(hour): ";
		cin>>train.time1.hour;
		cout<<"Departure time(minute): ";
		cin>>train.time1.minute;
		cout<<"From: ";
		cin.getline(train.place1.from,21);
		cout<<"To: ";
		cin.getline(train.place1.to,21);

		Sticket(choice);
		
}

Line 36 leaves a newline in the input buffer, so your getline() reads that and thinks you've entered an empty string. Try using ignore() to get rid of it.
