I faced this problem too. Re-ran the Visual Studio 2017 Installer, go to ‘Individual Components’ and select Windows 8.1 SDK. Go back to to the project > Right click and Re-target to match the SDK required as shown below:
By my knowledge there is no overall way to do this. If you look at the headers of cross platform/multiple compiler supporting libraries you’ll always find a lot of defines that use compiler specific constructs to determine such things: You probably will have to do such defines yourself for all compilers you use.

Static scoping means that x refers to the x declared innermost scope of declaration that has one. Since h is declared inside the global scope, the innermost x is the one in the global scope(it has no access to the xs in f and g, since it was not declared inside them), so the program prints 14 twice. Dynamic scoping means that x refers to the x declared in the most recent frame of the call-stack the … Read more
f2 is taking it’s arguments by reference, which is essentially an alias for the arguments you pass. The difference between pointer and reference is that a reference cannot be NULL. With the f you need to pass the address (using & operator) of the parameters you’re passing to the pointer, where when you pass by reference you just pass the parameters and … Read more
The problem is circular dependency. set.h includes set.cpp and set.cpp includes set.h.Remember that including a file simply pastes its code. There is no need for set.cpp to know about set.h as they will be one file when compiling.Also, you shouldn’t call set.cpp a cpp file. cpp files are ones that are meant to generate object … Read more
It’s short for “warn all” — it turns on (almost) all the warnings that g++ can tell you about. Typically a good idea, especially if you’re a beginner, because understanding and fixing those warnings can help you fix lots of different kinds of problems in your code.
The symlink to the 4.8.2 directory is nothing to worry about, it’s normal for the libstdc++ headers on Red Hat Enterprise Linux (and therefore CentOS) to be arranged like that. gcc –version will tell you the version of the gcc executable in your path. rpm -q libstdc++-devel will tell you the version of the package … Read more
When I do this: Everything works great. However, when I make it a vector of references instead: I get horrible errors like error C2528: ‘pointer’ : pointer to reference is illegal I want to put a bunch of references to structs into a vector, so that I don’t have to meddle with pointers. Why is … Read more
else doesn’ take any condition, but you’ve written this: which doesn’t do what you intend it to do. You want to do thos: Notice the difference. Also, there can be at most one else block, associated with an if block Or a chain of if, else-if, else-if blocks. That is, you can write this: Or, … Read more
