To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as follows:#include #includeintMain () {inti; floats

The Fibonacci Sequence, also known as the Golden series. In mathematics, the Fibonacci series are defined as follows by recursive Methods: F0 = 0, F1 = 1, Fn = F (n-1) + F (n-2) (n> = 2, in modern physics, quasi-crystal structure, chemistry, and other fields, the Fibonacci series are directly applied. Now, from an algorithm perspective, recursive and non-recursive methods are used for implementation:
