Is The Halting Problem Undecidable?

Is The Halting Problem Undecidable? Alan Turing proved in 1936 that a general algorithm running on a Turing machine that solves the halting problem for all possible program-input pairs necessarily cannot exist. Hence, the halting problem is undecidable for Turing machines. Is halting problem recursively enumerable? The language HALT corresponding to the Halting problem is

What Are Decidable And Undecidable Problems? The problems for which we can’t construct an algorithm that can answer the problem correctly in finite time are termed as Undecidable Problems. These problems may be partially decidable but they will never be decidable. What types of problems are undecidable? There are some problems that a computer can
