It won’t automatically convert (thank god). You’ll have to use the method c_str() to get the C string version. Note that it returns a const char *; you aren’t allowed to change the C-style string returned by c_str(). If you want to process it you’ll have to copy it first: Or in modern C++:
Given your newness to C++, I would not recommend building directly on the sockets APIs unless you can find no suitable library to use. Boost.Asio will give you a huge head start and expose you to the higher-level abstractions used in network programming. It’s easy when starting out building a sockets-based system to get something that ‘sort … Read more
I’m sorry if this is a repeat question but I already tried to search for an answer and came up empty handed. So basically I just want to add strings (single words) to the back of a vector and then display the stored strings as a single string. I am quite the rookie. Why doesn’t … Read more

A string literal is not a std::string. You throw the former, but try to catch the latter. Despite the fact a std::string may be constructed from a string literal, it won’t happen in a catch clause. The conversions which are allowed in a catch clause are detailed in [except.handle]/3: A handler is a match for an exception object of … Read more
invalid new-expression of abstract class type ‘box’ There is nothing unclear about the error message. Your class box has at least one member that is not implemented, which means it is abstract. You cannot instantiate an abstract class. If this is a bug, fix your box class by implementing the missing member(s). If it’s by design, derive … Read more
Libpng-1.6 is more stringent about checking ICC profiles than previous versions. You can ignore the warning. To get rid of it, remove the iCCP chunk from the PNG image. Some applications treat warnings as errors; if you are using such an application you do have to remove the chunk. You can do that with any … Read more
