Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
You are required to design an algorithm to keep asking a user to enter a number in the range of 1 to 100, not accepting any invalid numbers or characters. Which one of the following control structures should you use?
A
Boolean.
B
Iteration.
C
Selection.
D
Sequence.
Explanation: 

Detailed explanation-1: -5)Finiteness The algorithm must stop, eventually. Stopping may mean that you get the expected output OR you get a response that no solution is possible. Algorithms must terminate after a finite number of steps.An algorithm should not be infinite and always terminate after definite number of steps.

Detailed explanation-2: -Explanation: Stack data structure is most suitable to implement redo-undo feature. This is because the stack is implemented with LIFO(last in first out) order which is equivalent to redo-undo feature i.e. the last re-do is undo first.

Detailed explanation-3: -An algorithm is any well-defined computational procedure that takes some data value, or a set of values, as input and produces some value, or set of values, as output, always terminating with a result. An algorithm is thus a sequence of computational steps that transform the input data into the output data.

Detailed explanation-4: -If exponent == 1 the loop will execute once, making result equal to value, again the correct answer.
