I think you have something missing in the input array. It should have been [2,3,5,6,6,12,4,2]. Then the sum of the elements in reverse are the out put array. Where the out put would be [2,2+4,2+4+12,2+4+12+6,2+4+12+6+6,2+4+12+6+6+5,2+4+12+6+6+5+3,2+4+12+6+6+5+3+2]

Awesome.
I write down a wrong question. You fix it and give me the correct pattern!
Yes you are absoluetly right.

THERE IS AN ERROR IN THE ORIGINAL QUESTION. unnamed_array HAS THE CORRECT QUESTION.

Can't edit the original post now. Hope people see this.

I also thought there was a mistake like unnamed_array. But, then I thought it might be a little trickier pattern. Anyway, here is the solution for the original question with possible mistake but you can easily modify it for the corrected question:
{{
/* Input array is: */
/* [2, 3, 5, 6, 12, 4, 2] */

/* The output array is: */
/* [2, 6, 18, 24, 30, 35, 38, 40] */
#include "stdio.h"
void main()
{
int in_ar[7] = {2, 3, 5, 6, 12, 4, 2};

short len = sizeof(in_ar)/sizeof(int);
int* out_ar = malloc(sizeof(int)*(len + 1)); /* [2, 6, 18, 24, 30, 35, 38, 40]; */
out_ar[0] = in_ar[len - 1];
int j = len - 2;
int k = len - j - 1;

while (j >= 0) {
if (j == k) {
out_ar[k] = out_ar[k - 1] + in_ar[j];
}
else {
out_ar[k] = out_ar[k - 1] + in_ar[j];
j--;
}
printf("Cur int is : %d\n", out_ar[k]);
k++;
}
}

}}
