Question

Write a C function that sums all the elements of a n-dimensional vector:

int sum(int A[], int n)
/* Returns the sum of all elements of A */
{
/* TODO */
}

Answer 1

again wrong section..

Answer 2

nobody's in the CS section :(

Answer 3

everyone asks questions about CS here, so no one goes to CS

Answer 4

Anyway, here's my answer

int i, sum;
sum = 0;
for (i =0; i < n; sum += A[i++]);
return sum;

Answer 5

\[\vec{A}(0,5,1)\]
How's that vector represented? as A[0]=0, A[1]=5, A[2]=1? if yes then it should be correct

Answer 6

i'm just unsure if A[i++] works as it is intended
