here is my big probelm, it is going to first include the initial programming instructions and part of my program to try to solve it, I'm stuck big time.
Write a C program incorporating a main() function and at least 2 other functions which will do the following:
Create an array of 15 doubles and initialize it as follows:
the 0 through 4 elements : 14.83,19.24,0.84,1.98,3.47
and the 10-14 elements : 827.39,632.85,471.38,0,04,4.83
and all other elements 0.
Consider the two groups of non-zero numbers in the array as lists and create four pointers such that there is a pointer to the beginning(element 0) of the first list and the end(element 4) of the first list and likewise for the second list. Use names like first and last or hedad and tail or front and back to name your pointers.
***Call a function to print out the two lists,one list per line.
***Call a function to print out the values in the 4 first and last list elements with the names of the pointer variables that point to them.
Using array notation,sum the elements in the first list(0-4) and sum the elements in the second list(10-14) and subtract the sum of the first list from the sum of the second list. ***Print out the difference in a readable sentence.
***Call the print fucntion from above to print both lists again.
Call an insert fucntion to insert the value 1298.8314 at the end of the first list using pointer notation. Make sure the list pointers are updated.
***Call the print function from above to print both lists again.
***Call a fucntion to print out the values in the 4 first and last list elements with the names of the pointer variables that point to them.
Call an insert function to insert the value 0.369 as the new second element of the second list using pointer notation. Make sure the list pointer are updated.
***Call the print function from above to print both lists again.
***Call a function to print out the values in the 4 first and last list elements with the names of the pointer variables that point to them.
Using array or pointer notation, sum the elements in the current first list and sum the elements in the current second list and subtract the sum of the first list from the sum of the second list.
***Print out the difference in a readable sentence.
***Call the print function from above to print both lists again.
Here is my program so far and I'm stuck.
#include <stdio.h>
void arrayprint(double numArray[15]);
void pointerprint(double numArray[15],double *first,double *last,double *front,double *back);
void arraysubtract(double numArray[15]);
void arrayinsert(double numArray[15]);
int main()
{
double numArray[15]={14.83, 19.24, 0.84, 1.98, 3.47, 0, 0, 0, 0, 0, 827.39,
632.85, 471.38, 0.04, 4.83};
double *first=numArray;
double *last=first+4;
double *front=first+10;
double *back=first+14;
arrayprint(numArray);
pointerprint(numArray,first,last,front,back);
arraysubtract(numArray);
arrayinsert(numArray);
return 0;
}
void arrayprint(double numArray[15])
{
int i;
for(i=0; i<15; i++)
{
if(i<5)
{
printf(" %1.2f", numArray[i]);
}
else if(i==5)
{
printf("\n");
}
else if(i>9)
{
printf(" %1.2f", numArray[i]);
}
}
}
void pointerprint(double numArray[15],double *first,double *last,double *front,double *back)
{
printf("\n");
printf("first %1.2f last %1.2f front %1.2f back %1.2f\n",*first,*last,*front,*back);
}
void arraysubtract(double numArray[15])
{

void arrayinsert(double numArray[15])
