While loop for sum

Hi,

I need to read in an integer N from the keyboard and then use while loop to compute the value of the expression.

The expression is ((n+1)/sqrt(n)+n^3)

n = 1;
while true
  do something
  n = n + 1;
  if n > N; break; end
end

or

n = 0;
while true
  n = n + 1;
  if n > N; break; end
  do something
end

or

n = 1;
while true
  do something
  if n >= N; break; end
  n = n + 1;
end

or

n = 1;
while n <= N
   do something
   n = n + 1;
end

or

n = 0;
while true
   if n > N; break; end
   n = n + 1;
   do something
end
