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
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
if Statement The if statement is used to execute some code when a condition is true. Syntax: if (condition) { // Executes when the condition is true} The condition is the expression to be evaluated. If the condition is true, the statements within the braces will be executed. If the condition is false, the code … 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
In daily programming, we often need to let the program perform different operations based on different situations. For example: deciding whether to bring an umbrella based on the weather, categorizing grades based on scores, or displaying different content based on user permissions. All of these require the use of conditional statements. Today, I will guide … Read more
In C++, the if statement is a conditional statement used to choose whether to execute a specific block of code based on the result of an expression. The basic syntax of the if statement is as follows: if (condition) { code; } If the condition inside the parentheses is true, the code will be executed; … 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
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
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
