If you want to return a single-dimension array from a function you would have to declare a function returning a pointer as in the following example.

The problem is that since the array is allocated in the functions stack frame it ceases to exist when the function returns thus the caller gets a pointer to an area of memory. Now this p array contains a function. Then return array is essentially equivalent to return array0.

We dont return an array from functions rather we return a pointer holding the base address of the array to be returned. We can use arrays to return multiple values from a function. Return an ArrayList From a Non-Static Function in Java.

It is a collection of elements of same datatype. Return pointer pointing at array from function. In turn return other function pointer.

We will try to invoke this function in another class. The reasons are esoteric but understand that when an array value is returned from a function it decays into a pointer value. The reasons are esoteric but understand that when an array value is returned from a function it decays into a pointer value.

The following code example shows us how to use arrays to return multiple values from a function in C. A local array cannot be directly returned from a C function as it may not exist in memory after the function call. It is a template of structure.

C programming does not allow to return an entire array as an argument to a function. The same occurs when a naked array is passed in as a parameter. Program to Return Array In Java.

But we must make sure that the array exists after the function ends ie. You cannot return an array from a function in C. As such by wrapping an array in a class and returning instance of that class you can get around the restriction.
