Lesson 6 of C Language: if Condition Judgement = Making Programs Make Decisions ๐ค Learn to judge from scratch, make your program smarter in 5 minutes In the first five days, we learned to make the program “speak”, “remember”, “ask questions”, and “calculate”. Today, we will learn something even more powerfulโhow to make the program … Read more

Do kids lose points when writing C code after learning C++? Parents are also confused: Are C and C++ alternatives or complementary? Today, we will break down complex programming logic using two very intuitive life metaphors, making it easy for both parents to guide and children to learn independently! 1. Core Positioning: C is the … Read more
The use of the else statement in Python is quite extensive, as seen in common if-else combinations. However, many find the for-else structure, which can follow try statements or loops, hard to believe. Today, we will explore these often-overlooked constructs.For example, when writing search logic, we typically need a variable to track whether the target … Read more
11ใThe following C++ code is used to find the mirror number of N (the digits of N are reversed from the least significant to the most significant, but leading 0 will be ignored and not output), for example, if the input is 1234, the output will be 4321 , and if the input is 120, … Read more
1193 – Angled II Program Development Approach (For Beginners) Hello everyone! Today we will understand step by step how the “Angled II” program is designed and implemented. Step 1: Understand the Problem Requirements We need to create an nรn square matrix. Observing the output example, for instance when n=5: Dark version 1 2 3 4 … Read more
In the previous lecture, we learned about operators used for comparing values. However, mere comparison is not enough for a program to be functional; it also needs to possess “decision-making capabilities.” In this lesson, we will bring our code to life using if and if-else statements. Just like in real life, your program can now … Read more
Hello everyone! Today, I bring you two PLC control cases that are very suitable for beginners in electrical automation, helping you quickly grasp basic programming logic. Remember to bookmark and share this with your classmates to progress together! ๐ก 01Sequential Start and Stop ๐ Application Scenario: In industrial ventilation systems, multiple fans often need to … Read more
1. Nested if and if elseThe nested if and if else refers to including another if else statement within an if or else code block. This structure allows us to execute different code blocks based on multiple conditions.Framework 1:if (condition){ if(condition) { // Code Block 1 } else { // Code Block 2 }}else{ // … Read more
Previously, I introduced the concept of dual coils due to the PLC scanning cycle. Regarding this scanning cycle, I have found that many friends, when starting to write programs, often see no issues with the program, and the PLC shows no errors or alarms, yet the results are incorrect. This is likely due to the … Read more
