What is a pointer to a function A function pointer is a pointer variable that points to a function, not a pointer to an object. The function pointer itself should be a "pointer variable"; "In C, the function itself is not a variable, but you can

How the program works Before we start the journey, let's explore how the simplest C program works. To make the program simple enough, we can get the CPU to take instructions (fetch instruction) directly from Flash and execute it, and the program

Recently wrote the program, encountered a very worried about the problem is when the code reached a certain scale, the code will become very disordered, neither convenient to read, nor convenient debugging, more inconvenient to check the wrong. One

The undefined reference to ' sin ' error occurs when compiling a C program with a mathematical function using the GCC compiler. This error is generally caused by a lack of libraries. As a small program in the above diagram, the following problems
