Compile a function. When n is an even number, call the function to calculate 1/2 + 1/4 +... + 1/n. When n is an odd number, call the function 1/1 + 1/3 +... + 1/n ., Even number
First, write a function whose n is an even number:
Def peven (n): s = 0.0 for I in range (2, n + 1.0): s + =/I print 'value:', s
Write another function with n as an odd number:
Def podd (n): s = 0.0 for I in range (1, n + 1.0):

In C, suppose we have a function like this:
Int function (int A, int B)
You can use this function by using result = function. However, when a high-level language is compiled into a machine code that can be recognized by a computer, a problem arises: In the CPU, the computer cannot know how many or what parameters are required for a function call, and there is no hardware to save these parameters. That is to say, the computer does not know how to pass
