Is it possible to pass in a stringstream and have the function write to it directly?
I remember I saw a function invoked similar to something like this:
my_func(ss << "text" << hex << 33); 
315
How to Perform Extraction or Read Operation in StringStream in C++ Like the insertion, we can also perform extraction on StringStream in C++, like the cin >> operator. We can again do this by using the >> operator or the str() function.
You can't return a stream from a function by value, because that implies you'd have to copy the stream.
Very Informally: A string is a collection of characters, a stream is a tool to manipulate moving data around. A string stream is a c++ class that lets you use a string as the source and destination of data for a stream.
The stringstream class in C++ allows a string object to be treated as a stream. It is used to operate on strings. By treating the strings as streams we can perform extraction and insertion operation from/to string just like cin and cout streams.
Sure thing. Why wouldn't it be? Example declaration of such function:
void my_func(std::ostringstream& ss); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
