reading whitespaces in input

[ozair]

I am using 'string' header in program, the problem is that the function cin.getline() uses char* as its first argument rathar than a string class object... I also tried using getline(cin , string) function but I am encountering some problems in, for example, in this code..

getline(cin, YourGame);
for (;YourGame!="quit";)
{
MyGames.push_back(YourGame);
getline(cin, YourGame);
}

once I input 'quit', it is still waiting for another input and this time it can be anything..
here MyGames is vector<string> object...

So, I need a solution for this problem..

From the code you have given I don't particularly understand what the rest of your code might look at but I think you should use a while loop instead of a for loop.

hey, thanks for the suggestion, but that was not my concern...
this all the code...


#include <iostream>
#include <string>
#include <vector>
#include <conio.h>
using namespace std;

int main()
{
char choice='y';
string YourGame;
vector<string> MyGames;
vector<string>::iterator i;

cout << "Enter all the games you like(enter 'quit' to exit): ";

while (choice=='y' || choice=='Y')
{
getline(cin, YourGame);
for (;YourGame!="quit";)
{
MyGames.push_back(YourGame);
getline(cin, YourGame);
}

cout << "You entered a total " << MyGames.size() << " games.\n";
cout << "Would you like to enter some more? ";
cin >> choice;
}

cout << "\nHere are all the games you just entered: \n";

for (i=MyGames.begin(); i<MyGames.end(); i++)
cout << *i << endl;

getch();

return 0;
}

it runs with no problems if I use cin >>, but I wanted to read spaces, so I can't use cin.getline with string object and getline() function is giving problems as I stated in my first post...

EDIT: Removed because I misread the question.

You have some unnecessary code such as while (choice=='y' || choice=='Y'), and your for loop is not helpful. Take a look at this program bearing in mind that it hasn't got everything you want in it:

#include <iostream>
#include <string>
#include <vector>

int main()
{
    std::string yourGame;
    std::vector<std::string> myGames;
    std::vector<std::string>::iterator it;
    
    std::cout <<"Enter all the games you like: ";
    
    while(getline(std::cin, yourGame), yourGame.compare("quit")) {
       myGames.push_back(yourGame);
       std::cout << "Enter Game: ";
    }
    
    for (it=myGames.begin(); it<myGames.end(); it++)
      std::cout << *it << std::endl;
      
    std::cin.get();
    return 0;
}

arghhh, I didnt asked for what is necessary or what is unnecessary in my code!

the only problem is, once I input 'quit' in getline(), it should come out of the loop, but it doesnt, I have to give some other input in order to getout, I even used the string.compare function, but it still the same,

Are there functions to read a line with 'string objects'??? Is there something wrong with getline() function!?

I don't have this problem. When I enter quit on its own in its own line, it gets out on the double.

I know you didn't, that was just a bonus input from me for your poorly written code.

No. If there was it probably wouldn't be in the standard library.

That's the last comment i'm making in this thread.
