Part One: Overview of Program Control Structures 1.1 What is Control Flow In programming, control flow refers to the order in which instructions are executed in a program. By default, a program executes line by line from top to bottom in the order the code is written, which is known as sequential structure. However, real-world … Read more
Today’s topic is: Control Flow — enabling your program to make choices, loop, and have logic. Rust’s control flow is similar to Python but is stricter and safer. Day 3 Learning Plan (approximately 1–2 hours) Learning Objectives • Master <span>if</span>, <span>else if</span>, and <span>else</span> • Understand the three types of loops: <span>loop</span>, <span>while</span>, and <span>for</span> … Read more
Loop Syntax A loop repeatedly executes a set of statements until a specific condition is met. In C++, the while loop: as long as the condition is true, the while loop will repeatedly execute a set of statements until a certain specific condition is satisfied. Syntax: while (condition) { // Loop body, statements to be … Read more
1. Sequential StructureFrom top to bottom, from left to right, skip any indented methods or class methods directly2. Branching Structure (Selection Structure)(1) if~elseif condition: execute statementelse: execute statement if and else are mutually exclusive; only one clause can be executed during each run of the code The branching structure must have at least one if; … Read more
Basic Python Syntax 2 If-Else Basic Format if condition: # Actions to take if the condition is met else: # Actions to take if the condition is not met Example moon = 666 if moon == 666: print("Correct") else: print(f"Incorrect") Output: Correct No additional elements are needed after elseAnother example: m = 1 n = … Read more

It is the simplest of the three basic structures (sequence, selection, loop), reflecting a “top-down, … Read more
I will explain using relatively simple language, and I will provide analogies for each code snippet. It may become aesthetically tiring, so I hope for your support. print() The meaning is “print”, which is to output. You can fill the parentheses with numbers, strings (which must be enclosed in quotes), and variables.For example: when you … Read more
The word <span><span>while</span></span> means “during…”; thus, a <span><span>while</span></span> loop can be understood as “looping while…”. Indeed, in a <span><span>while</span></span> loop, the computer repeats execution of a certain block of code as long as the condition is met, and stops the loop when the condition is no longer satisfied. Let’s understand this looping pattern through the … Read more
for loop statement:Code for the “Knock the Table” game: #include <iostream>using namespace std; int main(){int counter = 0;for (int i = 1; i <= 100; i++) {int ge = i % 10;int shi = i / 10 % 10; if (ge == 7 || shi == 7 || i % 7 == 0) {cout << … Read more
1 Introduction Everyone knows that repeating the same action is called a loop. Similarly, in C++, there are loops. What are the specific uses of loops in C++? Of course, there are many, such as calculating 2 raised to the power of 11, which requires multiplying that number repeatedly. Another example is counting how many … Read more
