CodeBlocks string output delimitered

Question

I am testing string output for a program in CodeBlocks. Here is the code:

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

    int main(){

    string entry = "";
    while(entry!="x"){

        cout<<"Enter: "; 
        cin>>entry;
        cout<<entry.substr(0,1)<<endl;

    }
    return 0;
}

However prints the result as if it is delimitered by space and cout string "Enter" with wrong order as if it is bugged. What can be the reason and how can I solve this situation?

Output:

Enter: P q r
P
Enter: q
Enter: r
Enter:

The `>>` operator extracts whitespace-delimited things. There is a list of good books [here](https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list). — molbdnilo, Dec 16 '17 at 16:24
That's how streamed input works, normally. You probably want to use `getline` into a std::string instead. — Eljay, Dec 16 '17 at 16:25

To read a whole line, don't use cin >> whatever. It will stop reading when it encounters a whitespace (space, tab and newline). Use std::getline():

getline(cin, entry);

Now this becomes true:

assert(entry == "P q r");
