Thread: Question About Getline

Hi,

I've been programming some examples out of a book and I've noticed something about getline that's made me curious. In the following simple program, you enter a make and model of a car, and then it outputs it.

But say you change the line "cin.getline(make, 19);" to "cin.getline(make, 3);". Then, if you enter something like "ford" or anything longer than that, the program no longer asks you the second question. How come?

Code:

#include <iostream>
using namespace std;

char model[20];
char make[20];

int main()
{
    cout << "Enter make: ";
    cin.getline(make, 19);
    cout << "Enter model: ";
    cin.getline(model, 19);

    cout << make << " " << model;
    return 0;
}

Thanks.
