Web2 hours ago · 0. C/C++ has a remquo function that provides both a remainder and part of the quotient when dividing one number by another. I cannot seem to find remquo for python (the linked page has an example of why you would want such a function). As you can see from an example source implementation, getting it correct isn't trivial. WebOct 20, 2016 · The keyword class can be interchangable with typename in this case. The keyword inline makes it effient as the C++ compiler will inline this short code without actually calling it (which causes the stack frames creation and destruction)..
