Cin >> string, ss<<a<<string //the string is giving only 1 word, why?

[CosminPerRam]

Hi forum, i have an problem and a question:

The question, there's any funtion to put number to how much file's there in a folder ---See line 44---

The problem, if i said the "n" is Spag Heddy - It's me.mp4 it took only the word "Spag", why? I have to say the "n" its a string ---See line 53---

Thanks in advance!

cin>> reads input as far as the first space. If you want to enter a string containing spaces, use getline.

When you do that, be aware that cin>> will leave a '\n' in the buffer, so if you're going to use getline after using cin>>, clear the buffer.

[CosminPerRam]

but how to use it, you can give me an example? thanks in advance

I still dont know how to fix my problem with getline, please help me :/

[Moschops]

cin >> n; std::getline (std::cin,n);

[CosminPerRam]

Its not working, its something like its skiping the cin and go directly to start command, so its not working. I hope i will fix it :/

[Chervil]

if you're going to use getline after using cin>>, clear the buffer.

Here's one way.
change

    std::cin >> f1;

to

    std::cin >> f1 >> std::ws;

std::ws will read and discard whitespace - in particular the newline '\n' remaining after entering the value of f1.

Still dont work, The system cannot find the file Spag, HOW TO FIX IT????

[Chervil]

You need to combine the answers given by Moschops with the one I gave. Mine was only half a solution, the part needed to get the following getline to work.

[CosminPerRam]

cin >>n;

std::getline (std::cin,n);
         std::cin >> f1 >> std::ws;

Like this? (this is not working)

Anyway, i fix m problem, thanks for trying too!
