The above code seemed to work in a small test program, but once I tried it in my project, it did not work as expected. I changed it slightly to what I've linked below. Seems to work fine now.

Re: SStream, String, Integer, And Recursive 12 Years Ago by pseudorandom21 Personally I would rather not deal with "cin" failure, but rather a stringstream failure. I'm writing this in the textbox but it usually works when I do: [code] template<class int_type> int_type GetChosenNumber(std::istream &is, std::ostream &os){ int_type out; std::string in; std::getline(is, in); while( (std::… Re: SStream, String, Integer, And Recursive 12 Years Ago by mrnutty @OP or a more generic approach: [code] struct InvalidInputException : std::exception{ InvalidInputException(): std::exception("Error: Invalid conversion") {} }; //tries to get a data of type T, throws InvalidInputException if failed template<typename T> T prompt(const std::string msg){ cout << msg ; T res = T(); if( !… Re: SStream, String, Integer, And Recursive 12 Years Ago by pseudorandom21 Yes, good point Vijayan, I usually assume it's good input even if it has trailing crud for some reason.

Repeat: std::enable_if<> proposal was based on boost::enable_if<>, which is explained here: [url]http://drdobbs.com/cpp/184401659[/url] Alternatively, look up section 20.9.7.6 in the FDIS. Re: sstream/string problem 11 Years Ago by Ancient Dragon what compiler are you using? I know Visual Studio 6.0 had a bug that did that but it was fixed with one of its patches. Write another tiny program just to test if your compiler has a similar problem. Re: sstream/string problem 11 Years Ago by letterG im using microsoft visual c++ 6.0, so do I have to get a better compiler then? Re: sstream/string problem 11 Years Ago by Ancient Dragon get vc++ 2010 express -- its free, so is Code::Blocks/MinGW compiler. Or, download an install SP6 for your compiler from Microsoft web site. I don't know if its still available though. Re: sstream/string problem 11 Years Ago by Schol-R-LEA As an aside, you will want to use `int` as the return type of `main()` in the future. Strictly speaking, `void main()` isn't legal C++, even if some compilers accept it. Just a piece of advice, which you may need to know about as most newer compilers will flag `void main()` as erroneous, or at least give a warning. Re: sstream/string problem 11 Years Ago by letterG so my code isn't wrong at all then?, well thanks guys! Re: Returning a string. C++ SSTREAM 12 Years Ago by LevyDee Send everything you want to output into a string stream(#include <sstream>).

I do not know about classes though, so tomorrow I'll open that section and start studying it. The input is correct because the teacher sent it to us. That is what really troubles me. I have to go to bed now to wake up early, but I'll ask the teacher if he can help me tomorrow. If I can find the … Re: Strings, Sstream, and the death of both. 13 Years Ago by Rimojenkins [quote]Make sure you account for the spaces[/quote] I now see what you are saying.
