How does the % operator (modulo, remainder) work? You can think of the modulus operator as giving you a remainder count % 6 divides 6 out of count as many times as it can and gives you a remainder from 0 to 5 (These are all the possible remainders because you already divided out 6 as many times as you can)
c++ - Inheriting constructors - Stack Overflow Constructors are not inherited They are called implicitly or explicitly by the child constructor The compiler creates a default constructor (one with no arguments) and a default copy constructor (one with an argument which is a reference to the same type)
c++ - How do you create a static class? - Stack Overflow In the static class, the myGlobal variable is private, but still visible This is not as important as it seems, but still, in a DLL, showing a symbol that should be private to the DLL in an exported header could be awkward In the namespace, the myGlobal exists only in the CPP file (you can even go farther and make it static)
parsing - Parse (split) a string in C++ using string delimiter . . . If you have multiple delimiters, after you have extracted one token, you can remove it (delimiter included) to proceed with subsequent extractions (if you want to preserve the original string, just use s = s substr(pos + delimiter length());):
Why are #ifndef and #define used in C++ header files? The cost of opening a file, discarding all its contents, and closing it over and over might not sound like much, but for a large header included transitively by hundreds of other headers (e g windows h, the low-level stuff providing simple type definitions like stdint h, types h, etc ), the difference between opening it exactly once per source file and opening it a hundred times (where only
