C++ 20 (2a) New Features - Returning Value of the Spaceship Operator

The video tutorial explains the spaceship operator and its ability to return different types of ordering: strong, weak, and partial. Strong ordering includes less, equivalent, equal, and greater, with equivalent and equal being the same. Weak ordering lacks equal and is used for case-insensitive comparisons. Partial ordering includes less, equivalent, greater, and unordered, with unordered meaning no comparison is true. Strong and weak orderings can be converted to partial ordering, but not vice versa. These orderings are mainly used in generic programming and can be compared to literal 0.
