A question about getline and cin

[jimgeor]

here is my code and if you run it you 'll see that it has a bug

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

class example
{
    public:
        example();
        void print(){cout<<itsName<<endl<<itsNumber<<endl<<endl;}
    private:
        string itsName;
        int itsNumber;

};

example::example()
{
    cout<<"Enter Name"<<endl;
    getline(cin,itsName);
    cout<<"Enter Number"<<endl;
    cin>>itsNumber;
}
int main()
{
    example a[3];
    for(int i=0;i<3;i++)
    {
        a[i].print();
    }
    return 0;
}

BUT if i change getline(cin,itsName) with cin>>itsName it works fine
can you tell me why?

ps i'm a novice (c++) programer so there is a high possibility that my question is silly

refer the expected parameter types for getline()
istream::getline - C++ Reference

and implementation of std::cin
cin - C++ Reference

It will only work right if you enter one name otherwise if you enter maybe you name plus your surname the cout the 'itsname' it will give you the name you entered first only.
