How to work with a pointer to a dynamic array in "C"?

Question

C++ / C#

Let's say this piece of code:

float *arr;
arr = malloc( 16 * sizeof(float) );
arr[0] = 1.0;
arr[1] = 1.5;
arr[2] = 2.0;

And now I need to pass a memory reference from arr to the function, so that I can also work with the array from the function:

arr[3] = 1.0;
arr[4] = 1.5;
arr[5] = 2.0;

How to do it right? Thank you.

Answer 1

void workwitharray(float *array){
array[3] = 1.0;
array[4] = 1.5;
array[5] = 2.0;
}
workwitharray(arr);
