Problem solving process part 2

2. Implementation phase Implement the program in some programming language

Flowchart

(Dictionary) A schematic representation of a sequence of operations, as in a manufacturing process or computer program.

Flowchart

(Technical) A graphical representation of the sequence of operations in an information system or program. Information system flowcharts show how data flows from source documents through the computer to final distribution to users. Program flowcharts show the sequence of instructions in a single program or subroutine. Different symbols are used to draw each type of flowchart.

Problem solving process part 1

1. Problem solving phase Produce an ordered sequence of steps that describe solution of problem (Algorithm)

Decision Structure

A decision structure tests a condition and then takes one path if the condition is true, or another if the condition is false.

Information

Any knowledge that can be communicated

Code

Data type specifications and instructions for a computer that are written in a programming language

Electronic computer

A programmable device that can store, retrieve, and process data.

Programming Language

A set of rules, symbols, and special words used to construct a computer program

Computer Program

Data type specifications and instructions for carrying out operations that are used by a computer to solve a problem.

Data

Information in a form a computer can use.

Algorithm

Instructions for solving a problem or subproblem in a finite amount of time using a finite amount of data

Pseudocode

It is an artificial and informal language that helps programmers develop algorithms. Pseudo code is very similar to everyday English.

Programming

Planning or scheduling the performance of a task or an event.

Computer Programming

The process of specifying the data types and the operations for a computer to apply to data in order to solve a problem.

Data Type

The specification of how information is represented in the computer as data and the set of operations that can be applied to it.

Logical expression

a logical statement that is either TRUE or FALSE. Logical expressions can compare data of any type as long as both parts of the expression have the same basic data type. You can test data to see if it is equal to, greater than, or less than other data.
