This article mainly explains "what is the difference between python higher-order functions and C language function pointers". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what's the difference between python higher-order functions and C language function pointers?"

Python higher-order function: pass a function as an argument.

C language function pointer: pass in the function pointer as an argument, and the function pointer is also the basis of the polymorphic realization of C language.

We can see that they do have something in common. Let's take a look at the code of the two to accomplish the same function.

Python:

Def sub (aformab):

Return a Murb

Def test (a _

Return c (afort b)

A=test (2, 1, 1, sub)

Print (a)

C:

# include

Typedef int (* f) (int, int)

Int sub (int a pencil int b)

{

Return a Murb

}

Int test (int a _ line int b _ r f c)

{

Return (* c) (aPerm b)

}

Int main (void)

{

Printf ("% d\ n", test (2)

}

In fact, the test function takes the sub function as an argument, and then the main function calls the test function to complete a subtraction.

At this point, I believe you have a deeper understanding of "what is the difference between python higher-order functions and C language function pointers". You might as well do it in practice.
