    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.

    strlen() does that.

    I think its included in <string.h>
