Doing homework and I'm stuck (Fragments)

Philip Harris

I am having trouble interpreting how to write this fragment?
sum<--0
for i from 1 to n
sum <-- sum -1
for j from 1 to i
sum <-- sum + 2

Accepted answer
you also have to define 'n' with some int value

int sum = 0;
int n = ???;

for (int i=1; i <= n; i++)
{
sum -= 1;
for (int j=1; j<=i; j++)
sum += 2;
}

I really appreciate it man sometimes the way my instructor /book puts things makes the easy things hard at least for me. I might message you if i get stuck if that is cool with you.
