Usage

From this repository's own test project — built and run by CI, not written for the website.

// compat.safeint — assert the C++ class's normal arithmetic, non-throwing cast
// check, and both overflow and divide-by-zero exception paths.
#include <SafeInt.hpp>

#include <cstdint>
#include <cstdio>
#include <limits>

int main() {
    bool ok = true;

        if (!condition) {
            std::printf("FAIL: %s\n", what);
            ok = false;
        }
