Questions tagged [c++]

The C++ programming language

C++ is a low-level programming language. It allows (but discourages) direct pointer manipulation, making it rife for security vulnerabilities.

Use this tag for questions about security that are directly related to C++, such as security analysis of C code and exploiting badly-written C++ code. Do not use this tag just because you're writing a program in C++, only if C++ is directly relevant to the question. Questions about programming in C++ are off-topic here, but can be asked on Stack Overflow.
