c++ return std::stringstream from a function

[prolemur]

I have read that string streams are not copy-able and I'd have to use std::move(ss) when returning it, but it still won't compile. I also cannot return just the string because I need to follow the function's prototype. Thanks

we need more info

What more info could you possibly need?

std::stringstream returnStringStream() {
	std::stringstream ss;
	return ss;
}

what are you trying to accomplish?

There may be other ways of achiving it

We need to know what you're trying to do. That code you just posted should work fine.

I'm using Code::Blocks and it's lame compiler it come's with. I'm just putting some factorials into a stream separated by the letter x.

The function prototype I am given is this, and I cannot change it.

std::stringstream displayPrimeFactors(int** factorization, int length);

c:\program files (x86)\codeblocks\mingw\bin\..\lib\gcc\mingw32\4.7.1\include\c++\bits\ios_base.h|788|error: 'std::ios_base::ios_base(const std::ios_base&)' is private|

Sounds like you're using an outdated/non-compliant compiler. Try going to Settings > Compiler then under the compiler flags makes sure the "Have g++ follow the C++11 ISO C++ language standard" is checked (can try the c++14 option too.) If enabling those doesn't work, you'll need a newer compiler.

This is for an assignment so if it doesn't compile with the compiler they tell me to use(code::blocks'), then I get a zero. I'm gonna probably ask my prof about this if someone else doesn't next lecture.

 

Currently using GCC

So this was an issue on the assignment's part. It now will return a string, so we all good.
