#include <stdio.h>
#include <string.h>

typedef struct beaches 
{
int number;
struct beaches* next;
}beach;


int
main (void)
{
beach b1, b2, b3, b4;
beach *ptr;

b1.number = 27;
b2.number = 45;
b3.number = 61;
b4.number = 36;
b1.next = NULL;
b3.next = &b1;
b4.next = &b3;
b2.next = &b4;
ptr = &b2;
while (ptr != NULL)
{
printf ("%d\n", ptr -> number);
ptr = ptr -> next;
}


return (0);
}

P3) Complete the function only (no main program) that will take in an array of double numbers and will "return" a different array containing the inverted values (1/n). For example if the original array contains 1.0, 2.0, 3.0..., the inverted array will contain 1.0, 0.5, 0.3333... Your function must work with arrays of any size (same size for both arrays). Your function must also return the value of the last cell of the inverted array.

P4) What will be the output of this program?

#include <stdio.h>

int f1 (int x, double y)
{
int z;
z = x + y / 4;
return (z);
}

double f2 (double x)
{
int i;
double xx;
xx = 0.0;
for (i=1; i <= x; ++i)
xx = xx + f1(i,x);
return (xx);
}

int
main (void)
{
printf ("%.4f\n", f2(3.0));
return (0);
}
