Definition:Algorithm/Step

Definition
An algorithm consists of a finite set of steps, uniquely identified by means of a label, conventionally numeric.

A step of an algorithm consists of:


 * an operation


 * an instruction as to what the algorithm is to do next, which will be one of the following:


 * $(1): \quad$ By default: to move onto the next step in the sequence


 * $(2): \quad$ Based on the result of a condition, the specific step to perform next


 * $(1): \quad$ To terminate.

It is usual to include a statement in natural language which briefly describes the purpose of this step.
