This makes it easier to write cases where the return type non-trivially depends on the members, such as: Let R be the return type, each pair of subobjects a, b is compared as follows: Per the rules for any operator<=> overload, a defaulted <=> overload will also allow the type to be compared with <, <=, >, and >=. If the declared return type is auto, then the actual return type is the common comparison category of the base and member subobject and member array elements to be compared (see std::common_comparison_category). Comparing strings in a case-insensitive manner means comparing them without taking care of the uppercase and lowercase letters. Web programming/HTML Thanks for reading this far.

I would use stricmp(). It compares two strings without regard to case. Here are a few examples: Example 2: Compare Two Strings using String.Equals with case sensitivity Example 3: Compare two strings without case sensitivity. When the default semantics are not suitable, such as when the members must be compared out of order, or must use a comparison that's different from their natural comparison, then the programmer can write operator<=> and let the compiler generate the appropriate two-way comparison operators. If operator<=> is defaulted and operator== is not declared at all, then operator== is implicitly defaulted.
