10. Which of the following statements are true?
A. An algorithm may produce no output
B. An algorithm expressed in a programming language is called a computer program.
C. An algorithm is expressed in a graphical form known as a flowchart
D. An algorithm can have an infinite sequence of instructions.
(1) (A) and (B) only
(2) (A), (B) and (D) only
(3) (C) and (D) only
(4) (B) and (C) only
SHOW ANSWER
Explanation: An algorithm is a collection of well-defined, computer-implementable instructions expressed as flow chart that are used to solve a problem or perform a computation. Algorithms are invariably unambiguous, clear and provides specifications for tasks like measurements, data processing, and automatic reasoning.
Natural languages, pseudocode, flowcharts, drakon-charts, programming languages, and control tables are all examples of how algorithms can be expressed. Algorithm has well defined output, well defined intput, finiteness, clear and unambiguous, physical language independence. ©navclasses
