testing for blank line

How do I test for a blank student name
ie if ((pa+i)->fullname==blank line)
break;

Code:

---


int getinfo(student pa[], int n)
{
       
        int i;
        for (i=0;i<n;i++)
        {
                cout << "Enter the name of student "<< i+1 <<":";
                cin.getline((pa+i)->fullname,SLEN);
                if ((pa+i)->fullname=='\0')
                        break;
                cout << "Enter student "<<i+1<< " hobby:";
                cin.getline((pa+i)->hobby,SLEN);
                cout << "Enter student "<< i+1<< " ooplevel:";
                cin >>(pa+i)->ooplevel;
                cin.get();
        }
        return i;
}

Well Why dont you just get the length of the name and if its 0 then it was a blank line.

is there a function to determine the length?
can't find one in this book

strlen() does that.

I think its included in <string.h>
