Web1 day ago · For int, operator* it’s 1. For std::string, operator+ it’s "". These pairs of types and associative binary operators which have an identity element turn out to be surprisingly common in programming, they’re called monoids. Ben Deane has several great talks on monoids in C++, I’d highly recommend watching this one. WebEnter an integer: 2345 Reversed number = 5432 This program takes an integer input from the user and stores it in variable n. Then the while loop is iterated until n != 0 is false. In each iteration, the remainder when the value of n is divided by 10 is calculated, reversed_number is computed and the value of n is decreased 10 fold.
