C Language Structures (struct) From Beginner to Advanced 1) What is a Structure? A structure (<span>struct</span>) “packages” different types of logically related data into a whole, making it easier to pass, store, and manage together. Unlike arrays that can only hold “elements of the same type”, structures can hold “members of different types”. 2) Definition, … Read more
The conversion of a string to an integer (the library function is atoi) is a classic string processing problem in C, requiring consideration of various edge cases and exception handling. Below, we will implement a function similar to atoi and explain its implementation approach in detail. Functional Requirement Analysis Ignore leading whitespace characters in the … Read more
Content Hello everyone, I am Bug Jun~Recently, I came across a very interesting term “callback hell”, which refers to endless callback functions that ultimately lead to stack overflow and deadlock. The manifestation of this is multiple layers of nested function pointer callbacks, resulting in poor code readability and maintenance difficulties.Below is a simple example simulating … Read more
It is not possible to directly assign values to an array name.In C language, when we declare and define (after initialization) an array, if we want to reassign values directly to the array, the C compiler may prompt:assignment to expression with array type.For example, the following code: #include <stdio.h> int main(){ int a[] = {1,2}; … Read more
Talking about cars, today we discuss automotive development technology! I have previously written some articles mainly analyzing cars or the automotive industry, or sharing some automotive knowledge, but another area I really want to delve into, which also aligns with the positioning of this public account, is knowledge related to “automotive technology”. After all, we … Read more

Attempting to directly assign values to string type members of a structIn the following code, when we try to directly use the “.” operator to access the string (character array) member in the struct and assign a value, the compiler will prompt:assignment to expression with array type, which translates to assigning a value to an … Read more
1. Clipping Filter Method 1. Method: Determine the maximum allowable deviation between two samples based on experience (denote as A) When a new value is detected, determine: a. If the difference between the current value and the previous value is <= A, then the current value is validb. If the difference is > A, then … Read more
