Passing array to a function. Memory handling.

Question

Hi. May I work with the array in c++ this way? Is it OK? Mainly from the memory handling point of view.
Thanks.

void fill_arr(int xarr[], unsigned int xsize) {
...
}

int main() {
unsigned int size = 100;
int *arr = NULL;

arr = new int[size];
fill_arr(arr,size);

delete [] arr;
return 0;
}

Answer 1

You would need to take either a reference or pointer to the array as a parameter instead of the array itself.

Answer 2

@Jacob So far, what I wrote, looks like it is working. Can you please give me an example what do you mean? Thanks.

Trying this resulted in error:

void fill_arr(int *xarr[], unsigned int xsize) {
...
}

int main() {
unsigned int size = 100;
int *arr = NULL;

arr = new int[size];
fill_arr(&arr,size);

delete [] arr;
return 0;
}
