is it possible to use cin.getline in strings

Mrehman · #1 06-May-2008, 10:30

hey guyz what's up? my question is same as the title above. is it any way possible for you to use cin.getline in strings.if not then how do i read a whole line in this code. it's all the way at the bottom.

CPP / C++ / C Code:

#include <iostream>
#include <string>
using namespace std;
 
struct Information
{
	string name;
	string age;
	string state;
	
};


void main()
{  
	Information Member[100];
	
	cout<<"Data for Members :"<<endl;
	Member[0].name = "Yun Li";
	Member[0].age  = "19";
	Member[0].state = "California";
	
	Member[1].name = "Rashad Brooks";
	Member[1].age  = "22";
	Member[1].state = "New York";
	
	Member[2].name = "Anthony Miller";
	Member[2].age  = "27";
	Member[2].state = "Vermont";
	
	Member[3].name = "Andre Mitchell";
	Member[3].age  = "20";
	Member[3].state = "Texas";
	
	Member[4].name = "Kevin Lucas";
	Member[4].age  = "33";
	Member[4].state = "Mississippi";
	int i;
	for (i=0;i<5;i++)
	{
		cout << "Enter a name for user #" << i+1 << ": ";
		cin >> Member[i].name;
		

	}		
}

when i run the program it asks me to enter a name for member # 1. it did so but if i put the whole name in like Kevin Lucas and press enter it will come like this
please enter the data for member # 1
//i entered the whole name
it will display this:
please enter the data for member# 2
please enter the data for member #3
so basically it will skip the 2nd one. whenever i enter the whole name it will skip. how can i fix this.

[quote=Mrehman is it any way possible for you to use cin.getline in strings.[/QUOTE]

CPP / C++ / C Code:

        cout << "Enter a name for user #" << i+1 << ": ";
        getline(cin, Member[i].name);

I respectfully suggest that you to get a book or check an online reference such as http://www.cplusplus.com/reference/string/getline.html

I mean, it's OK to ask, but wouldn't either of these be quicker than posting a request for help and waiting for a helpful response?

Regards,

Footnote:
Note that cin.getline() is for char arrays. The global function getline() for std::strings is used as I show. In my opinion, there is rarely a (good) reason to use char arrays for things like this in a C++ program.

cin takes input as space delimited.
example:

CPP / C++ / C Code:

string a, b, c;
cout << "Enter three strings..." << endl;
cin >> a;
cin >> b;
cin >> c;
cout << "a : '" << a << "'" << endl;
cout << "b : '" << b << "'" << endl;
cout << "c : '" << c << "'" << endl;

Reacts the exact same way on either of the following inputs:

Code:

$ ./a.out
Enter three strings...
one two three
a : 'one'
b : 'two'
c : 'three'
$ ./a.out
Enter three strings...
one 
two 
three
a : 'one'
b : 'two'
c : 'three'

You may want to investigate cin.getline. Also, be sure to check the state of the stream. It is entirely possible to have bad things happen on malformed user input.
