Lesson 6 of C Language: if Condition Judgement = Making Programs Make Decisions 🤔 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 powerful—how to make the program … Read more
Introduction to C++ Programming 03 – Branching Structure Programming In real life, we often need to perform operations such as comparing sizes and determining equality, and then make corresponding decisions based on the results. The branching structure in C++ programming allows us to easily implement these operations. (1) Relational Operators and Relational Expressions In mathematics, … Read more
✅ Comprehensive Analysis of Control Flow in C Language: The if Statement 🌟 1. Single Branch if 📌 Executes if the condition is true, otherwise skips. #include <stdio.h> int main() { int age; printf("Please enter your age:"); scanf("%d", &age); if (age >= 18) { printf("Adult, can act independently!\n"); } return 0; } 🌟 2. if…else … 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
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
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
“From today on, study hard and make progress every day.” Repetition is the best method for memory; spend one minute each day to remember the basics of C language. “C Language Beginner’s Essential Knowledge Notes Series of 100 Articles”“ 25. if Statement: The Most Common Conditional Judgment 1.

Previous answer1: From the above image, we can see that the memory addresses of tu1 and tu2 are the same. This is because tu1 and tu2 belong to immutable sequences. To optimize performance, Python can reuse the value of immutable objects when their values are the same.2: From the above image, we can see that … Read more
The Clever Use of if and switch Statements in C Language In C language, selection structures are important tools for controlling the flow of program execution. They allow the program to execute different blocks of code based on different conditions. This article will detail two commonly used selection structures: <span>if</span> statement and <span>switch</span> statement, and … Read more
Understanding the if Statement: A Deep Dive into C Language Control Structures In programming, control flow refers to a series of statements that determine the order of execution of a program. The <span>if</span> statement is one of the most fundamental and commonly used control structures in C language. It allows us to execute different blocks … Read more
