TRUE


FALSE


Either A or B


None of the above

Detailed explanation1: If an algorithm doesn’t have an output, it is equivalent to the empty program. (There’s no way to observe internal computations, so a program that does the computation and discards it is for all intents and purposes equivalent with one that doesn’t perform the computations at all.)
Detailed explanation2: An algorithm has input values from a specified set. From each set of input values, an algorithm produces output values from a specified set. The output values are the solution to the problem.
Detailed explanation3: Output specified: An algorithm should have 1 or more welldefined outputs and should match with the expected output. If there will be any output at all, you have to know what kind of data and how much it should be.
Detailed explanation4: Any algorithm is a program. Explanation: The statement is false. An algorithm is represented in the form of a programming language is called a program. Any program is an algorithm but the reverse is not true.
Detailed explanation5: Algorithms produce a result In our simple definition of an algorithm, we stated that an algorithm is a set of instructions for solving a problem. Unless an algorithm produces some result, we can never be certain whether our solution is correct.
