No, it's not possible to include an array in a member initializer list for a variadic struct. Variadic structs are structures that allow a variable number of arguments to be passed to the constructor. These arguments are stored in a member variable, which is usually an array or a pointer to an array.
However, arrays cannot be used in member initializer lists, as they are not constant expressions. A member initializer list is used to initialize the member variables of a class or struct with constant values. The values are determined at compile-time and cannot be changed at runtime.
If you need to initialize a variadic struct with an array, you can either pass the array as an argument to the constructor, or you can pass the array elements one by one as separate arguments to the constructor. The first approach is more efficient, as the entire array is passed to the constructor in one call, while the second approach requires multiple calls to the constructor, one for each element in the array.
In summary, it's not possible to include an array in a member initializer list for a variadic struct, but you can pass the array as an argument to the constructor or pass the elements of the array one by one as separate arguments to the constructor.
It's worth mentioning that there are alternative approaches to using variadic structs for passing arrays to a constructor. One approach is to use a non-variadic struct and pass the entire array as an argument to the constructor. This allows you to use a member initializer list to initialize the member variables of the struct with the values from the array.
Another approach is to use a class instead of a struct. Classes can have constructors with variable arguments, just like variadic structs, but they also have the ability to use member initializer lists. This means that you can initialize member variables of a class with values from an array, just like with a non-variadic struct.
Ultimately, the choice of using a variadic struct, a non-variadic struct, or a class will depend on your specific requirements and the design of your code. Consider the trade-offs between these approaches in terms of performance, ease of use, and readability when making your decision.
In conclusion, arrays cannot be used in member initializer lists for variadic structs, but you can use non-variadic structs or classes to achieve similar functionality, depending on your requirements and the design of your code.
