Array pass to function

Array is a collection of similar data type which occupies continuous location on memory. Array’s name is a constant pointer which point first element of array. So when an array is passing to a function. Address of first element pass to function instead of value. If any change made inside of function body with array, then it affects actual value of passed array. Following program demonstrate this fact.

int update(int[]);

void main()

{
