c++ - std::cin input with spaces? -

#include <string>  string input; cin >> input; 

the user wants enter "hello world". cin fails @ space between 2 words. how can make cin take in whole of hello world?

i'm doing structs , cin.getline doesn't seem work. here's code:

struct cd {     string cdtitle[50];     string artist[50];     int number_of_songs[50]; };  cin.getline(library.number_of_songs[libnumber], 250); 

this yields error. ideas?

you have use cin.getline():

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