Answer #1: rdbuf()->in_avail() can be used to get the count of available characters ready to be read in from a stringstream , you can use that to check if your stringstream is “empty.” I’m assuming you’re not actually trying to check for the value null .

What library is Stringstream?

How do you clear a Stringstream in C++?

The clear() member function is inherited from ios and is used to clear the error state of the stream, e.g. if a file stream has the error state set to eofbit (end-of-file), then calling clear() will set the error state back to goodbit (no error). For clearing the contents of a stringstream , using: m. str(“”);

How do you split in C++?

Different method to achieve the splitting of strings in C++

1. Use strtok() function to split strings.
2. Use custom split() function to split strings.
3. Use std::getline() function to split string.
4. Use find() and substr() function to split string.

What does Stringstream SS do?

stringstream basically allows you to treat a string object like a stream , and use all stream functions and operators on it. I saw it used mainly for the formatted output/input goodness. One good example would be c++ implementation of converting number to stream object.

What is Rdbuf C++?

The insertion (<<) operator, which is preprogrammed for all standard C++ data types, sends bytes to an output stream object. Insertion operators work with predefined “manipulators,” which are elements that change the default format of integer arguments.

What is string in C programming?
