Lesson 7 of C Language: Loops = Making Programs Repeat Tasks 🔁 Master loops from scratch, write repetitive tasks in 5 minutes Imagine doing push-ups: you need to do 100, counting each time from 1, 2, 3… up to 100. This is the essence of “loops”—repeating the same task many times according to rules, with … Read more

🔁 C Language Loop Structures (Part 2): Detailed Explanation of while and do-while Loops Author: IoT Smart Academy 💡 1. Why do we need while? Sometimes we do not know how many times a loop should execute, for example: The user keeps entering data until they input 0 to end Repeatedly entering a password until … 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
Lesson 11: do-while Loop B2068 Count 4-Digit Numbers That Meet Conditions #include <iostream> using namespace std; int main() { int n, num, g, s, b, q, cnt = 0; cin >> n; int i = 1; do { cin >> num; // Input number g = num % 10; // Units s = num % … 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

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
