Question

what if I want to pass an array by ref? An array is a pointer to its first element, and I want to pass the ‘whole array’ by ref. If I define

void someFunction(double& adouble){...}

then adouble is a ref to a double, not an array with doubles.

If I define

void anotherFunction(double* adouble){...}

then my argument is a pointer to a double or an array, but it is not passed by ref, right?

Thanks and regards

For a specific size:

void foo(double (&array)[100]);

For any size:

template <size_t N>
void foo(double (&array)[N]);
