C++ IDE
The online C++ IDE for high school computer science
#include <iostream>
int main() {
double length = 14.5;
double width = 7.5;
double area = length * width;
std::cout << "The area is " << area << " square feet" << std::endl;
return 0;

Runs in the browser — nothing to install.
Automated grading
Tests run against every submission.

Edit the lesson, starter code, and tests.
Browser-Based C++ IDE
JuiceMind's online C++ IDE compiles and runs C++ in the cloud — students write, compile, and debug without a local toolchain. Built for K-12 classrooms, from a first cout statement to the pointers and data structures a systems course is built on.
Instant C++ Compilation
Compile and run C++ with one click. No GCC install, no makefile, no local setup.
Test Cases & Autograding
Configure unit tests that run against student code and return instant feedback automatically.
Built-in Error Detection
Compiler messages point students to the exact line that broke, in plain view.
Works on Chromebooks & Tablets
Any device with a web browser. Nothing to install, update, or get past IT for.
Standard Library Support
Vectors, strings and streams — the parts of the standard library a CS course actually uses.
Save, Share & Submit
Student work saves automatically and can be shared with a link or turned in for grading.
