http://en.cppreference.com/w/cpp/language/array#Array_to_pointer_decay Nov 14, 2016 at 3:34am raboki898(9) @cire oh that make sense. When supplying variable names are they the same ones as the ones used when declaring the function?
But first, we need to cover two subtopics. Array to pointer conversions (array decay) In most cases, when a C-style array is used in an expression, the array will be implicitly converted into a pointer to the element type, initialized with the address of the first element (with index 0...
If I understood the question you seem to be asking for a pointer to an array, it can be done the following way: int main(void) { int array[5] = { 1, 2, 3, 4, 5 }; int i, (*p)[5]; p = &array; for (i = 0 ; i < 5; i++) printf("%d\n", (*p)[i]); return...
printf("%lu\n", NUM_ELEMS(pointer)); The output on my system is 2, indicating that a pointer is twice the size of an integer. To avoid accidental pointer passing, I contemplated possible solutions. #define NUM_ELEMS(a) (assert((void*)&(a) == (void*)(a)), (sizeof(a)/sizeof ...
In C++, when you pass an array to a function, it will decay into a pointer. Usually, you pass the size of the array to the function as a separate parameter, rather than within the square brackets. Using sizeof on arrays passed as parameters, Possible Dupli...
Those are all addresses in the pointer array, but the compiler doesn’t know what those addresses will be. The compiler fills the elements with temporary values and adds six relocation entries to the binary, one for each element. The loader will fill out the array at load time....

So this is a true reference to the array and does not convert to a pointer on the function side (in the background)? Yes. You need to know these two things when talking about "array decay": First, the compiler silently rewrites function parameters that have array types. ...
