DDC: a declarative debugger for C++

A declarative debugger for C++ is presented, called DDC. A declarative debugger receives as input an incorrect computation, builds a debugging tree based on the execution of the program and, after asking questions to an oracle (typically the user), points out a fragment of code that is the cause of the failure. We present the debugger’s main features, such as three different navigation strategies, using test cases as oracles, support for nonterminating programs and a tree transformation
