WebFeb 13, 2024 · Passing arrays to functions When an array is passed to a function, it's passed as a pointer to the first element, whether it's a stack-based or heap-based array. The pointer contains no other size or type information. This behavior is called pointer decay.
WebIt is to be remembered that there's no such thing as passing an array directly to a function in C [while in C++ they can be passed as a reference (1)]; (2) is passing a pointer to the array and not the array itself. Always passing an array as-is becomes a pointer-copy operation which is facilitated by array's nature of decaying into a pointer. 3.
WebSep 28, 2024 · It is the reason behind omitting the higher dimension when we pass multidimensional arrays to functions.

Because statically-allocated arrays have to be allocated at compile time, the bounds of each dimension must be constants (or, at the very least, constexprs, i ...
WebArrays can be constructed from any fundamental type (except void ), pointers, pointers to members, classes, enumerations, or from other arrays of known bound (in which case the array is said to be multi-dimensional). In other words, only object types except for array types of unknown bound can be element types of array types.
