What is it you are trying to achieve? 1, 1, 2, 3, 5, 8, 13, 21, 34, . . . write a program which generates the first n terms of this sequence, where the value of n is entered by the user, given the first two terms of the sequence. scuccessive terms are to be stored in an array. What is the problem you are having? im kind of stuck on this one i keep getting errors. Describe what you have tried to solve this problem i have written this program below. Turing: var number : array 1 .. 10 of int var sum := 0 put skip for counter : 1 .. 10 put "Enter number ", counter, ": " .. get number (counter) end for put skip put "The ten numbers in order of entry are: " put skip for counter : 1 .. 10 put number (counter) : 5 .. end for for counter : 1 .. 10 sum := sum + number (counter) put sum end for |

The sequence is generated by taking the previous TWO numbers and summing them, not the whole sequence:
Given your existing code, this should be a relatively simple modification. You already have something that lets you ask for a user-input number; all you have to do is do that part twice. You already have something that sums across a group of numbers. All you have to do is find a way to sum only the "current" number and the "previous" number. |
