c - Assign 1 value of a 3D array to a 1D array -

i have 3d array arr1[16][8][9] , want assign contents of array 1d array arr2[36]. i'm trying:

arr2[0] = arr1[0][0][0]; arr2[1] = arr1[0][0][1]; ...... arr2[8] = arr1[0][0][8]; 

i'm calling function:

func_arr(int arr2[36], int arr1[16][8][9]) 

the function declaration goes like:

void func_arr(int arr2[36],int arr1[][8][9]); 

but array assignment seems invalid. better approach it?

function calling seems incorrect. replace below line

func_arr(int arr2[36], int arr1[16][8][9]) 

with

func_arr(arr2, arr1); 

type of first function argument int [36] , passing arr2[36]. assuming arr2 int arr2[36], type of arr2[36] int , type mis-match. arr2[36] int located @ address after arr2 ends.
