Explain that, when used in a program,
the repetition structure
directs the computer to repeat one or more instructions until some condition is met, at which time the computer should stop repeating the instructions. Note that the repetition structure is also referred to as a loop or iteration.
Which of the following is a set of step by step instructions that accomplish a task?
- A set of step-by-step procedures for accomplishing a task is known as a(n) algorithm.
- An algorithm is a well-defined procedure that allows a computer to solve a problem.
What is the term that refers to the sequence in which a computer executes program instructions?
A program
is a sequence of instructions stored in main memory. When a program is run, the CPU fetches the instructions and executes or follows the instructions.
Which type of structure do all programs use?
Following the structured program theorem, all programs are seen as composed of
control structures
: “Sequence”; ordered statements or subroutines executed in sequence.
When an algorithm is used in a computer program it allows the computer to perform a task?
When an algorithm is part of a computer program, the process included in the algorithm ✔ is automated . When an algorithm is used in a computer program, it allows the computer to perform a ✔
repetitive task
.
What are the required steps to develop a good program?
- Brainstorming and planning.
- Requirements and feasibility analysis.
- Design.
- Development & coding.
- Integration and testing.
- Implementation and deployment.
- Operations and maintenance.
What are three examples of computer programs?
- Operating system.
- A web browser like Mozilla Firefox and Chrome can be used to view web pages on the Internet.
- An office suite can be used to write documents or spreadsheets.
- Video games are computer programs.
Is a person who writes code and communicates instructions to a computer?
Someone who writes software or programs for computers is called
a programmer
. … Programmers use a variety of computer languages to write the code (or instructions) that helps computers do the things their users want them to do.
What is a sequence coding?
Description. Sequences are
the main logical structure of algorithms or programs
. When creating algorithms or programs, the instructions are presented in a specific correct order. A sequence can contain any number of instructions but each instruction must be run in the order they are presented.
Where are the basic instructions of the computer stored?
Instructions are stored
in memory
and the contents of the PC register are used as the starting address from where the next to be executed instruction is read. Because the length of an 68k instruction is bytes can vary decoding and reading the instruction from memory (steps 1 and 2) is an iterative process.
What are the 3 types of control structures?
The three basic types of control structures are
sequential, selection and iteration
. They can be combined in any way to solve a specified problem. Sequential is the default control structure, statements are executed line by line in the order in which they appear. The selection structure is used to test a condition.
What are the three structures of a basic program?
Surprisingly, it can often be broken down into three simple programming structures called
sequences, selections, and loops
. These come together to form the most basic instructions and algorithms for all types of software.
What is structure example?
Structure is a constructed building or a specific arrangement of things or people, especially things that have multiple parts. An example of structure is
a newly built home
. An example of structure is the arrangement of DNA elements.
Which programming language came first?
The first commercially available language was
FORTRAN (FORmula TRANslation)
, developed in 1956 (first manual appeared in 1956, but first developed in 1954) by a team led by John Backus at IBM.
What are the three types of programming design?
- Creational. These design patterns are all about class instantiation or object creation. …
- Structural. These design patterns are about organizing different classes and objects to form larger structures and provide new functionality. …
- Behavioral.
What is the characteristic of a good algorithm?
Input: a good algorithm
must be able to accept a set of defined input
. Output: a good algorithm should be able to produce results as output, preferably solutions. Finiteness: the algorithm should have a stop after a certain number of instructions. Generality: the algorithm must apply to a set of defined inputs.
