Question

I have a problem with overloading >> operator for string class;
here is my class:

class str
{
    char s[250];
    public:
    friend istream& operator >> (istream& is, str& a);
    friend ostream& operator << (ostream& os, str& a);
    friend str operator + (str a, str b);
    str * operator = (str a);
    friend int operator == (str a, str b);
    friend int operator != (str a, str b);
    friend int operator > (str a, str b);
    friend int operator < (str a, str b);
    friend int operator >= (str a, str b);
    friend int operator <= (str a, str b);
};

and here is overloaded operator:

istream& operator >> (istream& in, str& a)
{
    in>>a.s;
    return in;
}

the problem is that it reads the string only to first space(only one word from sentence).

I solved it. Found the answer on dreamincode 😀

Answer 1

The behavior for operator>> is to read until the first whitespace character. Change your function to the following:

istream& operator >> (istream& in, str& a)
{
    in.getline( a.s, sizeof(a.s) );
    return in;
}
