How do I use cin to take in a sentence?

Question

#include <iostream>
#include <string>
using namespace std;

int main() {
string sentence;
cin >> sentence;
cout << sentence;
}

^ This code should let me input a string, but it breaks off at the first word. If I input "Hello World" and output the string, I get only "Hello". Why is it like that? How can I input the whole sentence?

Answer 1

Have a look at this too,
# include <iostream.h>
# include <conio.h>
main()
{
char name[20],city[20];
clrscr();
cout<<"PLEASE ENTER THE NAME:->";
cin.getline(name,20);
cout<<"PLEASE ENTER THE CITY:->";
cin.getline(city,20);
cout<<"NAME IS:->"<<name<<endl;
cout<<"CITY IS:->"<<city<<endl;
}

Answer 2

use getline() instead of cin. (header file for getline function is stdio.h)

Answer 3

Thank you so much!! I used #include <stdio.h> but it wouldn't perform the getline function. It gave no errors either. I also was using namespace std. It was pretty weird.

Answer 4

So, is it working without stdio?? or not working at all?

Answer 5

#include <iostream>

int main () {
std::string name;
std::cout << "Please, enter your full name: " << std::endl; std::getline (std::cin,name);
std::cout << "Hello, " << name << "!\n";
return 0;
}

I copied the example from a site

Answer 6

#include <iostream>
using namespace std;

int main () {
string name;
cout << "Please, enter your full name: " << endl; getline (cin,name);
cout << "Hello, " << name << "!\n";
return 0;
}

nvm, it works like this, thank you so much. I would upvote your responses, but each time i try, it says "no internet connection" even though im posting stuff
