What is the syntax for using the restrict keyword for a 2d array function parameter?

Question

I have an array declared in my main function: float A[n][n];

My goal is to pass it to a function with the restrict keyword: void func(int

Answer 1

The pointer can be restrict. All below forms are equivalent:

void func(int n, float A[restrict n][n]);
void func(int n, float A[restrict][n]);
void func(int n, float (* restrict A)[n]);
