EMBRACING USER DEFINED LITERALS SAFELY for Types that Behave as though Built-in Pablo Halpern phalpern@halpernwightsoftware.com CppCon 2021 This work by Pablo Halpern is licensed under a Creative bookstore near you! Talks in this series: ■ Embracing User Defined Literals Safely for Types that Behave as though Built-in – Pablo Halpern, Tuesday 9am ■ Embracing (and also destroying) Variant Types

That type is introduced in the next section. It can be challenging to remember how div and mod behave when either the divisor or dividend is negative, as this behavior may vary across different programming Since we have not yet introduced references or pointers, you should expect copy semantics. Strings behave just like all the other simple data types we have used before, such as integers, floating-point modifies only s1, not s2. This might not be surprising to you, but other programming languages may behave differently. For example, the assignment might not copy the textual content but only create a reference
