General Functions. Pointers are often used as function arguments when we want to return more than one value from the function. In each of the following problems, write the indicated function, and then develop a main function for testing the function:

Write a function that determines the maximum and minimum values from a one-dimensional integer array. Assume that the corresponding function prototype statement is

void ranges(int x[], int npts,int *max_ptr,           int *min_ptr);

where npts contains the number of values in array x, and max_ptr and min_ptr are pointers to the variables in which to store the maximum and minimum values in the array.
