Question

For this program you will declare some variables in main, call a function do_something and print out some results.

declare a constant SIZE outside of main and initialize it to 6.

in main:

Declare an dynamic array of pointers to doubles of size SIZE. Call the array dynamic_arr_ptrs_to_dbl.

Declare an alias to the array called dynamic_arr_ptrs_to_dbl_alias.

Declare a pointer to an integer called size_ptr and initialize it to be a reference to SIZE.

Declare a static array of doubles called static_arr_ptrs_to_dbl of size SIZE and initialize it to:

{ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 }

Call a function do_something using the call:

double **returned_pointer = do_something (dynamic_arr_ptrs_to_dbl_alias, static_arr_ptrs_to_dbl, size_ptr);

After to call, print out the doubles in the dynamic array returned by do_somehting as follows (It is not necessary to show the decimal point and two zeros):

Element 0 is 1.00

Element 1 is 2.00

Element 2 is 3.00

Element 3 is 4.00

Element 4 is 5.00

Element 5 is 6.00

Press any key to continue . . .

Outside of main:

Create a definition of the function do_something.

Inside the function:

Set the first group of 3 elements of the dynamic array to references to the first three elements of the static array using pointer notation for array accesses.

Set the second group of 3 elements of the dynamic array to references to the second 3 elements of the static array using square bracket notation for array accesses.

Explanation / Answer

#include<stdio.h>

#define SIZE 6

do_something(double *dynamic_arr_ptrs_to_dbl_alias[], double static_arr_ptrs_to_dbl[], int *size_ptr){

}

int main()
{
   int i;
   double *dynamic_arr_ptrs_to_dbl[SIZE];
   for(i=0; i< SIZE ;i++)
    dynamic_arr_ptrs_to_dbl[i] = malloc(sizeof(double));

   tydef dynamic_arr_ptrs_to_dbl dynamic_arr_ptrs_to_dbl_alias;

   int *size_ptr = SIZE;

   double static_arr_ptrs_to_dbl[SIZE] = {1.0,2.0,3.0,4.0,.5.0,6.0};

   double **returned_pointer = do_something(dynamic_arr_ptrs_to_dbl_alias, static_arr_ptrs_to_dbl, size_ptr);
   for(i=0; i<SIZE; i++)
   printf("Element %d is %lf", returned_pointer[i]);
}
