c++ Accessing shared buffers concurrently

[User4699]

I'm having a problem getting my buffer(string) to print out everything that the user inputs. When I run my code the buffer only prints out the last thing that is inputted. I've tried just about everything and I really do not know what else to do. I'm new to c++ so I have not got familiar with the language just yet. Any help would be greatly appreciated.

#include <iostream>
#include <string> 
using namespace std;



int main()
{
string name;
string quote;
string answer;

cout<< "Enter user name: ";
cin>> name;
cout<< "Enter the quote: ";
cin>> quote;	
cout<< "\nAny more users?(enter yes or no) ";
cin>> answer;

do
{
cout<< "\nEnter user name: ";
cin>> name;

cout<< "Enter the quote: ";
cin >> quote;

cout<< "\nAny more users?(enter yes or no): ";
cin>> answer;

} while (answer == "yes");

if(answer == "no")
{

string buffer;

buffer = "The buffer contains:\n ";

cout<< buffer << name << ": " << quote; 
}
else 
cout<< "Invalid response";
}

It only prints the last name that was input because when cin >> name is called cin will erase the current contents if name and replace it with the new keystrokes. If you want to keep all the names in memory then you will have to put them in an array, preferably a std::vector.

std::vector<std::string> namelist;

...
cout << "Enter a name\n";
cin >> name;
namelist.push_back(name);

...
...
// now display all the names that were input
for(int i = 0; i < namelist.size(); i++)
{
   cout << namelist[i] << '\n';
}

Thanks but its still not working for some reason. I dont know what i'm doing wrong I placed it in my code but its still not repeating the whole user input at the end. Should I take my do/while loop out?

Post new code because I can't see what you have done.

	}

else
cout<< "Invalid input";
}

move the declaration of that vector up outside the do loop. Its contents are being trashed on each iteration of that do loop. You have to declare it outside the loop so that its contents are preserved.
