C++ having probs with getline function

[sabby]

I want to use the getline() so that i can enter a entire name in on line. (with spaces)
The prob is that i am initializing the variable as "N/A" and saving it to a text file. it is declared as a string. look at the code:

#include <iostream.h>
#include <fstream>
#include <cstdlib>
#include <string>
using namespace std;
 
//Account data structure
struct account
{
 string user;
 string enter_password;
};
 
//Dining Data Structure
struct Dining
{
 account username;
 string name; // the variable that i'm using to store the name 
 string time;
 int persons;
 char status;
};
 
// Array declaration
Dining seats[8][4];
char reserve[] = "C:\\Seat Reserving.txt";
 
void show();
 
void username_entry();
 
/*
password user_pass[5];
char username[] = "C:\\Username Password Storage";
*/
 
void initialise();
 
void clear();
 
//Seats reserving
void to_reserve();
int input();
 
void showed_up();
 
 
int main()
{
  ifstream check_b4_start;
 
  check_b4_start.open(reserve);
 
   if(check_b4_start.fail())
    {
      cout<<"The file failed to open"<<endl;
      cout<<"No file was found"<<endl;
      cout<<"File created"<<endl;
      initialise();
      system("PAUSE");
      system ("cls");
    }
   to_reserve();
   //show();
  //username_entry();
 
 
      system("PAUSE");
      return 0;
}

 {

sorry for the lack of documentation.

Hi,can u post just troubleshooting part because this code is just to big?

sabby-

Please take a look at our Posting Guidelines, specifically the part about not posting full code, but rather the section that you're having trouble with, as well as the part about using code tags.

[sabby]

sorry guys. i want to know how to make that little window with the scroll bar to help minimize the space it takes up.

//Account data structure
struct account
{
string user;
string enter_password;
};

//Dining Data Structure
struct Dining
{
account username;
char* name;
string time;
int persons;
char status;
};

seats[n][x].name = "N/A";//this clashes with the below input
//it is saved as a text file

cout<<"\nWho is reserving this seat";
cin.getline(sea ts[row][coloumn].name); // trying to use getline() for input to text file

You use code tags ([code'] code here [/code'] but w/o the apostrophe).
Also, getline takes two arguements. You have only one. You need another telling you the size of the data you want to get from the stream. That should probably fix your problem.

So, even if i have the variable declared as a string i have to put an other argument to show how many characters?

Yes,
so for example if I do this:

string mystring;
cin.getline(mystring, 10);
 

and the user enters "Some random string", mystring will get "Some rando".
Does that help?

THANK YOU SOOO MUCH. that was stressing me out and all i had to do was add a limiter.
