This involves allocating memory for the array within the function and then returning a pointer to this memory. To return an array using pointer follow the below syntax: Here, arr is the name of the pointer pointing to the array. n is the size of the array.

To return an array, create one outside the function, pass it by address into the function, then modify it, or create an array on the heap and return that variable. Both will work, but the first doesn't require any dynamic memory allocation to get it working correctly.

Dec 26, 2013 · The proper C solution is to use malloc to allocate an amount of space that you can use as an array, and return the pointer to that array. double * myFunc(){ double * v = malloc(10*size of(double)); return v; }

In C a function can only return one element, so to return an array you must return a pointer which can contain the address of the first element of that array. And that's what you're doing in your code. You can access both values by correctly indexing the …
