How Does C 23 Revolutionize Multi-Argument Array Operator Usage?

Multi-Argument Array Operator in C : A Comprehensive Explanation

Prior to C 23, it was impossible to overload the array operator ([]) to accept multiple arguments. Attempts to do so, like the code provided by the user, would result in a compilation error citing an excessive number of parameters.

Overloading Operator() as a Workaround

As a workaround, users could overload the operator() instead. This approach is illustrated in the C FAQ section on creating a subscript operator for a matrix class.

C 23 and Multiple Arguments for [] Operator

However, C 23 introduces a significant change, allowing multiple subscript arguments to be passed directly to the [] operator. This can be seen in the cppreference page's demonstration, provided by cigien in a subsequently deleted answer.

Conclusion

In summary, multi-argument array operators were not supported in C before version 23. Overloading operator() served as a workaround. However, with the release of C 23, multiple subscript arguments can be directly passed to the [] operator, simplifying the syntax and enhancing the functionality of array-based classes.
