The if/then/else operation is a conditional statement.

A sequential search is the technique of looking at all the items in a list one at a time, starting at _______ of the list, until we either find what we are looking for or come to the end of the list.

____ operations provide the computing agent with data values from the outside world that it may use in later instructions.

Explain the importance of the concept of building blocks in the use of algorithms.

During the initial phases of design, we should be thinking and writing at a highly ____________________ level.

Pseudocode is a formal language with rigidly standardized syntactic rules and regulations. _________________________

Natural language is a set of English language constructs designed to resemble the statements in a programming language but that do not actually run on a computer. _________________________

What is the problem with using natural language to represent algorithms?

Briefly define the concept of iteration.

Once an algorithm has been developed, it cannot be used in the construction of other algorithms.

Having an infinite loop in an algorithm is an error.

____ operations send results from the computing agent to the outside world.

Pattern matching can only be applied to graphics and pictures.

Which statement exemplifies abstraction?

____________________ operations allow us to alter the normal sequential flow of control in an algorithm.

The process of searching for a special pattern of symbols within a larger collection of information is called object matching. _________________________
