When arrays are passed into functions, they undergo array-to-pointer conversion. This means an array of type T[N] will simply decay into T*. Notice how the size information has been lost. All that remains is a pointer to the first element of the array. Here is a quote from the Standard: 4.2 Array-to-pointer conversion An lvalue … Read more

You can’t do it in a completely portable way. Rather than dealing with int64_t, let us consider int8_t. The principle is almost exactly the same, but the numbers are much easier to deal with. I8_MAX will be 127, and I8_MIN will be -128. Negating I8_MIN will give 128, and there is no way to store … Read more
