std::cin input with spaces?

#include <string>

std::string input;
std::cin >> input;

The user wants to enter "Hello World". But cin fails at the space between the two words. How can I make cin take in the whole of Hello World?

I'm actually doing this with structs and cin.getline doesn't seem to work. Here's my code:

struct cd
{
    std::string CDTitle[50];
    std::string Artist[50];
    int number_of_songs[50];
};

std::cin.getline(library.number_of_songs[libNumber], 250);

This yields an error. Any ideas?

Solution

  • You have to use cin.getline():

    char input[100];
cin.getline(input,sizeof(input));
