The understanding of two-dimensional arrays as function parameters and two-dimensional arrays in C language

When a two-dimensional array is used as a function parameter to accept a two-dimensional array in the key function, it is degraded to a pointer to an array.

In this reference to the idea in C and pointers: multiple-bit array names as function arguments are passed in the same way as one-dimensional array names--a pointer to the first element of the array. But the difference between the two is that

Each element of a multidimensional array is itself another array, and the compiler needs to know its dimensions in order to evaluate the subscript expression for the function parameter.
