Missing vc_runtimeminimum_x86.msi and installation won’t work
Go to Control Panel–Programs and Features, uninstall the Visual C++ 2015 Redistribute items. After that, run the tool: https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed. Re-run the VS 2017 installer as administrator, then click the icon besides ‘Launch’ and choose ‘Repair’ to repair the VS 2017.
Why would we call cin.clear() and cin.ignore() after reading input?
The cin.clear() clears the error flag on cin (so that future I/O operations will work correctly), and then cin.ignore(10000, ‘\n’) skips to the next newline (to ignore anything else on the same line as the non-number so that it does not cause another parse failure). It will only skip up to 10000 characters, so the code is assuming the user will … Read more
Why am I getting string does not name a type Error?
Your using declaration is in game.cpp, not game.h where you actually declare string variables. You intended to put using namespace std; into the header, above the lines that use string, which would let those lines find the string type defined in the std namespace. As others have pointed out, this is not good practice in headers — everyone who includes that header will also involuntarily hit the using line and import std into their … Read more
Using the fstream getline() function inside a class
the function for streams that deals with std::string is not a member function of istream but rather a free function it is used like so. (the member function version deals with char*). It is worth noting there are better safer ways to do what you are trying to do like so: don’t reinvent the wheel; … Read more
C++ error: “Array must be initialized with a brace enclosed initializer”
The syntax to statically initialize an array uses curly braces, like this: This will zero-initialize the array. For multi-dimensional arrays, you need nested curly braces, like this: Note that Array_size must be a compile-time constant for this to work. If Array_size is not known at compile-time, you must use dynamic initialization. (Preferably, an std::vector).
C++ request for member ‘’ in ‘’, which is of non-class type ‘’
is a function declaration rather than variable. In c++ anything that can be parsed as a function declaration takes that parsing over the variable alternative. Removing the () would make it a variable.
push_back vs emplace_back
In addition to what visitor said : The function void emplace_back(Type&& _Val) provided by MSCV10 is non conforming and redundant, because as you noted it is strictly equivalent to push_back(Type&& _Val). But the real C++0x form of emplace_back is really useful: void emplace_back(Args&&…); Instead of taking a value_type it takes a variadic list of arguments, so that means that you can now perfectly … Read more
