How do I check if a StringStream variable is empty/null?

Question

Just a quick question here guys. I\'ve been searching to no avail so far.

A bit more info here:

stringstream report_string;

report_string << \         


        

Answer 1

Use eof() instead.

Sample Code:

stringstream report_string;
if ( !(report_string.eof()) ) 
    cout << "report_string EMPTY! \n";
