编程序，使用如下所谓的简单变量“数据平移”方法来求出Fibonacci数列的第n项（的具体项值）并显示在屏幕上（正整数n通过键盘输入）：说明变量old1=1，old2=1，newItem；新的Fibonacci项newItem总是“距它最近”的前两项（old1与old2）的累加和。而后通过“old1=old2 old2=newItem ”进行所谓的“数据平移”。接着计算另一个新的Fibonacci项newItem，依次循环，直到求出数列的第n项时为止。

Fibonacci数列的计算公式如下：

fib（1） = 1；

fib（2） = 1；

fib（n） = fib（n-1） + fib（n-2）； //对大于等于3的任意n

-Programmed, use the following so-called simple variables　Data Translation　approach in order to obtain the first Fibonacci series n-item (the specific items of value) and displayed on the screen (positive integer n, through keyboard input): Descr iption of variables old1 = 1, old2 = 1, newItem　new items NewItem Fibonacci always　away from it recently,　the first two (old1 with old2) and cumulative. Then through　old1 = old2 old2 = newItem　the so-called　data translation.　Then a new calculation of the Fibonacci item newItem, followed by cycle, calculated until the first series until n items. Fibonacci series of calculation formula is as follows: fib (1) = 1　fib (2) = 1　fib (n) = fib (n-1)+ Fib (n-2) // greater than or equal to 3 on the arbitrary n
