We can read a line by using getline function.

There are two situation , we know the size of a line , or 

we don't know the size of a line.

if we know the size , 

// istream getline 

#include <iostream> 

using namespace std; 

int main () 

{ 

char name[256], title[256]; 

cout << "Enter your name: "; 

cin.getline (name,256); 

cout << "Enter your favourite movie: "; 

cin.getline (title,256); 

cout << name << "'s favourite movie is " << title; 

return 0; 

}

if we don't know the size ,

// getline with strings 

#include <iostream> 

#include <string> 

using namespace std; 

int main () 

{ 

string str; 

cout << "Please enter full name: "; 

getline (cin,str); 

cout << "Thank you, " << str << ".\n"; 

}

// the getline is a global function in the string library here.
