An online Cpp compiler lets you write, run, and test Cpp code instantly in your browser—no installation or setup required. Just open Nottri.com, select Cpp, and start coding. Whether you're a student, teacher, or developer, our platform provides a fast, accessible, and powerful way to practice, learn, and build projects from anywhere.
Traditional development environments require complex setup processes, dependency management, and often expensive software licenses. With Nottri.com's online Cpp compiler, you can skip all the hassle and dive straight into coding. Our platform supports the latest Cpp features, libraries, and frameworks, ensuring you're always working with cutting-edge technology.
Traditionally, online compilers take your code, send it to a remote server, and execute it using standard stdin (for input) and stdout (for output). You write code, click "Run", and see the results in a simple output box. But most platforms only offer basic execution in a shared or restricted environment, limiting what you can do.
The typical workflow involves: writing code in a basic text editor, submitting it to a queue, waiting for execution on shared resources, and receiving limited output. This approach often leads to slow performance, security concerns, and restricted functionality that doesn't reflect real-world development scenarios.
Nottri.com revolutionizes online coding by providing each user with their own isolated Linux environment. This isn't just a code executor—it's a complete development workspace that mirrors professional development environments.
cpp main.cpp, pip install, npm install)The inspiration for Nottri.com came from experiencing the frustrations of existing online coding platforms. We identified key pain points that developers, students, and educators face daily:
Most platforms suffer from slow execution, long queue times, and laggy interfaces that interrupt the coding flow.
Shared environments pose security risks, with limited isolation between users and restricted access to system resources.
Basic code runners lack the tools and flexibility needed for real-world development and learning scenarios.
Our solution addresses these challenges by providing a platform that combines the convenience of online access with the power and security of local development environments. We've built Nottri.com to be the platform we wished existed when we were learning to code.
ls, mkdir, grep, etc.)pip, npmStarting your coding journey with Nottri.com is incredibly simple:
Once you sign up on Nottri.com, you’re not just getting a compiler — you're getting a full project development workspace.
Just like GitHub or Replit, you can create new coding projects, organize them, and come back to continue anytime. But here’s what makes Nottri.com even more powerful:
flask run, npm install)Whether you're building a Flask web app, a React frontend, a Python script, or just solving DSA problems — Nottri's powerful editor and real terminal give you all the tools you need.
pip, npm, etc.We believe coding tools shouldn’t be expensive or complicated. That’s why Nottri.com offers one of the most affordable and flexible pricing systems on the internet — way cheaper than Replit, GitHub Codespaces, or any other cloud IDE.
Instead of complicated monthly plans, we use a simple credit-based system:
And here’s the best part…
Your credits are yours forever. Whether you buy 10 or 1000 credits — you can use them anytime, with no expiry date.
This gives you full freedom — pay only when you need power features.
We love consistency — and we reward it!
Every time you log in daily, you build a streak. And here’s what you get:
Even if you don’t buy credits, you can still earn them — just by showing up and learning or coding daily.
We understand that:
That’s why we offer fully custom pricing options:
Just tell us your needs — and we’ll make a plan just for you!

C++ is a powerful general-purpose programming language that supports procedural, object-oriented, and generic programming. It is widely used for game development, system programming, and competitive programming.
g++ --version in your terminal or command prompt.Let’s write our first C++ program:
#include <iostream>
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
}
Save this code as hello.cpp and compile it using g++ hello.cpp -o hello. Run the program by executing ./hello.
C++ supports various data types and variables that need to be declared before use.
// Example:
int age = 25;
double pi = 3.14159;
char grade = 'A';
bool isStudent = true;
C++ uses if, else if, and else for decision-making.
// Example:
int num = 10;
if (num > 0) {
std::cout << "Positive number" << std::endl;
} else if (num == 0) {
std::cout << "Zero" << std::endl;
} else {
std::cout << "Negative number" << std::endl;
}
// Example:
for (int i = 0; i < 5; i++) {
std::cout << i << std::endl;
}
// Example:
int count = 0;
while (count < 5) {
std::cout << count << std::endl;
count++;
}
#include <iostream>
void greet(const std::string& name) {
std::cout << "Hello, " << name << "!" << std::endl;
}
int main() {
greet("Alice");
return 0;
}
#include <iostream>
class Person {
public:
std::string name;
int age;
void introduce() {
std::cout << "Name: " << name << ", Age: " << age << std::endl;
}
};
int main() {
Person p;
p.name = "Alice";
p.age = 25;
p.introduce();
return 0;
}
#include <iostream>
int main() {
int num = 10;
int* ptr = #
std::cout << "Value: " << *ptr << ", Address: " << ptr << std::endl;
int& ref = num;
std::cout << "Reference Value: " << ref << std::endl;
return 0;
}
// Writing to a file:
#include <iostream>
#include <fstream>
int main() {
std::ofstream file("example.txt");
if (file.is_open()) {
file << "Hello, C++!" << std::endl;
file.close();
}
return 0;
}
// Reading from a file:
#include <iostream>
#include <fstream>
#include <string>
int main() {
std::ifstream file("example.txt");
std::string line;
if (file.is_open()) {
while (getline(file, line)) {
std::cout << line << std::endl;
}
file.close();
}
return 0;
}
#include <iostream>
#include <vector>
int main() {
std::vector<int> nums = {1, 2, 3, 4, 5};
for (int num : nums) {
std::cout << num << std::endl;
}
return 0;
}
C++ builds on the C standard libraries and provides additional libraries for advanced functionality, such as:
iostream: For input and output operations, such as cin and cout.string: For manipulating and managing strings.vector, map, set: For efficient data structures.algorithm: For common algorithms like sort, reverse, and unique.thread: For multithreading capabilities.
