MyClass& boom(int i, std::string s) { int value {i}; MyClass mc; mc.Initialize(i,s); return mc; } const and constexpr functionsYou can declare a member function as const to specify that the function isn't allowed to change the values of any data members in the class. By declar...
myFunction() is the name of the function void means that the function does not have a return value. You will learn more about return values later in the next chapter inside the function (the body), add code that defines what the function should do...

The _itoa, _ltoa, _ultoa, _i64toa, and _ui64toa functions convert the digits of the given value argument to a null-terminated character string and store the result (up to 33 characters for _itoa, _ltoa, and _ultoa, and 65 for _i64toa and _ui64toa) in buffer. If radix equals ...

When you dereference an iterator to "zipped" range you get a tuple of the elements the iterators were holding.Example usage:array<int,4> iseq{{1,2,3,4}}; vector<float> fseq{1.2,1.4,12.3,4.5,9.9}; vector<string> sseq{"i","like","apples","a lot","dude"}; array<double,5> ...
