Question

Write a function that determines the maximum and minimum values from a one-dimensional array. Assume that the corresponding function prototype statement is void ranges(int x[], int npts, int *max_ptr, int *min_ptr) where npts contain 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.

Answer 1

Answer:

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

{

   *max_ptr=*min_ptr=x[0];

   for(int i=1;i<npts;i++)

   {

       if(x[i]>*max_ptr)        //this will put max value in  max_ptr

           *max_ptr=x[i];

       if(x[i]<*min_ptr)  //this will  put min value in min_ptr

           *min_ptr=x[i];

   }

}

Explanation:

The above function can be called like :

                                    ranges(x,n,&max,&min);  

where x is array and n is number of elements and max and min are address of variables where maximum and minimum values to be stored respectively.
