Write a function in C named find_elem which takes the following arguments:

integer elem

integer array

int size

with size being the array size, and elem the element you have to find in the array.

If elem is part of the array, return the first position of the element in the array. If elem is not part of the array return -1

For example:

Test	Output
int array[] = {4, 2, -6, -1}; printf("%d", find_elem(4, array, 4));	0
int array[] = {4, 2, -6, -1}; printf("%d", find_elem(-4, array, 4));	-1
