Basic doubt

hello shouldn't the code below return 11 for "hello there", it returns me the size of the first word i.e 5 for hello

Code:

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

int main(){
	string a;
	cin>>a;
	cout<<a.size();
}

well if i take the input in the code itself as string a = "hello there". i get 11.

i suspect its some thing related to input stream buffer or something. I am naive at this.

cin's >> operator will stop at whitespace. If you want to read a whole string, do this:

Code:

#include <iostream>

int main()
{
    std::string s;
    std::getline(std::cin, s); 
    std::cout << s << std::endl;
}
