I can’t assign a null to a String? No. std::string is not a pointer type; it cannot be made “null.” It cannot represent the absence of a value, which is what a null pointer is used to represent. It can be made empty, by assigning an empty string to it (s = “” or s = std::string()) or by clearing … Read more
Dynamic linking can reduce total resource consumption (if more than one process shares the same library (including the version in “the same”, of course)). I believe this is the argument that drives it its presence in most environments. Here “resources” includes disk space, RAM, and cache space. Of course, if your dynamic linker is insufficiently flexible there is … Read more
If you have any source file that includes GameObjects.h before ProjectilObject.h or does not include ProjectilObject.h directly, then the compiler will first find the declaration of ProjectilObject through the include in GameObjects.h before knowing what WorldObject is. That is because GameObjects.h first includes ProjectilObject.h and then declares WorldObject. In that case the include of GameObjects.h … Read more
The following code uses no if else constructs. The formatting can be got by using setw, used for setting the width of integers.Following code produces perfect output.
check that “filename.exe” is not running, I guess you are using Microsoft Windows, in that case you can use either Task Manager or Process Explorer : http://technet.microsoft.com/en-us/sysinternals/bb896653 to kill “filename.exe” before trying to generate it.

I’m using a vector to implement the “hands” in the blackJack class, and I’m using a structured data type declared in another class, which is publicly inherited. The error I’m worried about is the compiler I’m using telling me that … Read more
If you already haven’t done it, try adding “SDK Path\Include” to: And add “SDK Path\Lib” to: Also, try to change “Windows.h” to <windows.h> If won’t help, check the physical existence of the file, it should be in “\VC\PlatformSDK\Include” folder in your Visual Studio install directory.
You can follow this answer to see many different ways to process CSV in C++. In your case, the last call to getline is actually putting the last field of the first line and then all of the remaining lines into the variable genero. This is because there is no space delimiter found up until the end of file. Try … Read more
You are trying to access the struct statically with a . instead of ::, nor are its members static. Either instantiate ReducedForm: or change the members to static like this: In the latter case, you must access the members with :: instead of . I highly doubt however that the latter is what you are going for 😉
You should add the keyword const like in the example above.
