Grade 8 C++ · Learn at your own pace
Short lessons, C++ coding practice, teacher-assigned quizzes and learning milestones—connected to your classroom and saved progress.
New students join with a teacher's class code. Existing students sign in with their Student ID and password.
#include <iostream>
int main() {
std::cout << "Hello, CodeQuest!\n";
std::cout << "I am learning C++.";
return 0;
}Read the statements in order and predict what they display. Code Lab helps you save a solution and submit it for teacher feedback.
Hello, CodeQuest! I am learning C++.
Use your classroom C++ compiler to compile and run downloaded .cpp files.

Introduction
Explain what an algorithm and a C++ program do, then trace a simple program.
Sign in to open lesson →Program structure & output
Recognize the parts of a C++ program and print a message on a new line.
Sign in to open lesson →Data types & operators
Store whole-number values in int variables and use them in a calculation.
Sign in to open lesson →Console input
Read a number into a declared variable, use it in a calculation, and display the result.
Sign in to open lesson →Operators
Apply arithmetic operators and explain integer division and remainder.
Sign in to open lesson →Conditions
Choose between two actions using a comparison and an if/else statement.
Sign in to open lesson →Loops
Use initialization, a condition and an update to print a countdown.
Sign in to open lesson →Loops & input
Use a while loop to process values until a sentinel appears, without adding the sentinel to the total.
Sign in to open lesson →Functions
Define a function with a parameter, return a calculated value, and call it from main.
Sign in to open lesson →Arrays
Access valid array indexes and use a loop to total five values.
Sign in to open lesson →Strings

A classroom learning journey
Read a focused lesson, trace an example, check your understanding and ask your teacher for help.
Write your own C++ solution, save your draft and explain how you tested your approach.
Use final teacher feedback to revise your work. Saved rewards and badges record your progress.
Ask your classroom teacher. Choose the matching grade and section during student registration. A paused enrollment or replaced code needs your teacher’s current instructions.
Yes. Start with the first program lesson and follow the sequence through variables, input, decisions, loops and functions. Checkpoints can be retried while you learn.
Your teacher publishes work to your grade and section. Quiz schedules and attempt limits are checked by the server. Coding assignments may also have a deadline and a work timer.
Code Lab saves your source and explanation. Your teacher reviews the submitted version and saves the final rubric scores and feedback. Guided code checks help you look for common mistakes.
The public homepage shows platform totals and course topics. Student code, quiz answers, roster identities and class join codes are available only through the appropriate signed-in account. Students can choose how their nickname and avatar appear to classmates on the leaderboard.
