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

An easy check would be to see if the string content of the stream is empty or not:

#include
#include

int main(){
std::stringstream report_string;
report_string << ""; // an empty strin g

//emptiness check of stringstream
assert(report_string.str().empty());
}
