1 - for finding the size of an array in c

int arr[] = {6, 5, 12, 10, 9, 1};

int size = sizeof(arr) / sizeof(arr[0]);

printf("\n size is %d",size);

if array is of any other data type then we change it accordingly

2 - while passing an array to a function in c there's no need for square braces when it is being called but there's a need for the same in the passed function or where the function actaully is
