Frequently Asked Questions

Find Quick Answers

How accurate is this memory leak checker?

This tool provides simulated analysis based on common memory leak patterns and C++ best practices. While it can detect many common issues, it's not a replacement for running actual tools like valgrind or AddressSanitizer on your compiled code.

What types of memory issues can it detect?

The tool can detect: memory allocations without corresponding deletes, double delete attempts, array new/delete mismatches, potential use-after-free scenarios, and common resource leak patterns in C++ code.

Is my code sent to external servers?

Yes, the code analysis happens server-side to provide comprehensive checking. However, no code is stored permanently and all processing is done in memory only for the duration of the analysis.

What C++ standards does it support?

The analyzer supports C++11, C++14, C++17, and C++20 code. Make sure to select the appropriate standard version in the configuration options for best results.
