what does Unambiguous mean
This means that the instructions cannot be misunderstood . simply saying ‘turn’ would be ambiguous because you could turn right or left.
what does Sequence mean
An ordered set of instructions
what does algorithm mean
a precise method for solving a problem
what does high level programming language mean
A programming language that resembles natural human language.
what does flowchart mean mean
A graphical representation of an algorithm. Each step in the algorithm is representative by a symbol. Symbols are linked together with arrows showing the order in which steps are executed.
what does Pseudo-code mean
A structured code like language that can be used to describe an algorithm
what does Variable mean

what does logical operator mean
