Thread: Two name into one string variable problem

Hello my friends, I'm Panos and this is my first post here in CBoard Forums

Take a look to my C++ code:

Code:

#include <iostream>
#include <string>

int main()
{
    std::cout << "What is your name? ";
    std::string name;
    std::cin >> name;
    std::cout << "Hello, " << name << std::endl << "And what is yours? ";
    std::cin >> name;
    std::cout << "Hello, " << name << " nice to meet you too!" << std::endl;
    return 0;
}

No errors. Let's launch this:
Attachment 9434

Everything work perfect. Now let's launch it again giving two names (firstname & lastname) as input.
Attachment 9435

As you can see, it doesn't prompt me to insert the second name because it uses the my lastname (Georgiadis) and treat it like this way.

Is there any way to avoid this happening ?

You should use std::getline to read in an entire line of text. Using std::cin >> stops at the first whitespace, but std::getline will read the entire line including spaces.

Thank you Daved

Is there a reason you don't just use

Code:

using namespace std;

I think it cleans it up a lot and makes it much easier to read.

I prefer the way the OP does it. It makes things clearer (IMO) and more consistent, especially when programs get larger. Since it's bad practice to use the using directive in header files, for example, you end up typing std::string in the header and string in the source file. Plus I prefer to see that the name comes from the standard library as opposed to from my code.
