g++ 11 · C++17
C++ compiler API
Compile and run user-submitted C++ with one HTTPS request. CodeForge compiles with g++ 11 in C++17 mode with -O2, runs the binary in an isolated sandbox, and returns compiler output, stdout, stderr and the exit code.
Example: run C++ with one request
Submit the source and stdin, then poll GET /v1/executions/{id} until it finishes.
The program
#include <iostream>
#include <vector>
#include <algorithm>
int main() {
int n; std::cin >> n;
std::vector<int> v(n);
for (auto &x : v) std::cin >> x;
std::sort(v.begin(), v.end());
for (int x : v) std::cout << x << " ";
std::cout << std::endl;
}The request
curl -X POST https://api.tatvastack.com/v1/executions \
-H "Authorization: Bearer $CODEFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"language":"cpp","source":"#include <iostream>\n#include <vector>\n#include <algorithm>\n\nint main() {\n int n; std::cin >> n;\n std::vector<int> v(n);\n for (auto &x : v) std::cin >> x;\n std::sort(v.begin(), v.end());\n for (int x : v) std::cout << x << \" \";\n std::cout << std::endl;\n}","stdin":"5\n4 1 5 2 3"}'The result

}FAQ
C++ execution questions
Which C++ standard and compiler flags are used?
g++ 11 with -std=c++17 -O2.
How do I detect a segmentation fault?
The execution returns status RUNTIME_ERROR with a non-zero exitCode instead of hanging or failing the request.
Is bits/stdc++.h available?
Yes, the GNU standard library headers are included with g++.
Are fork bombs and memory bombs contained?
Yes. Process, memory, file and time limits are enforced on every run, and a sandbox that cannot be verified clean afterwards is discarded.
