A few symbols are needed to indicate the necessary operations in flowchart. These symbols have been standardized by the (ANSI).
While programmers have a good deal of freedom in creating flowchart. The (ANSI) has recommended a number of general rules and guideline to help standardize the flow-charting process.
Pseudo-code is another program planning tool used for planning logic. "Pseudo" means imitation or false and "Code" refers to the instructions written in a programming language. Pseudo-code is an imitation of actual computer instruction. Since pseudo-code emphasizes the design of a program, it is also known as Program Design Language (PDL).
Flowchart have the following limitation: Flowchart are very time consuming and laborious to draw with in proper symbol and spacing especially for large complex program. Any change or modification in the program logic will usually completely new flowchart. There are no standards determining the amount of detail that should be included in a flowchart.
Use of flowchart for program planning provides following benefits: Better communication A flowchart is a pictorial representation of a program. Therefore, it is easier for a programmer to explain the logic of a program to some other programmer. Proper program documentation Program documentation involves collection, organizing, storing and otherwise maintaining a complete historical record of …
A flowcharts is a pictorial representation of an algorithm. Programmers often use it is a program planning tool for visually organizing a sequence of step
In order to qualify as an algorithm a sequence of instruction must passes the following characteristic
The term algorithm refers to the logic of a program. It is a step-by-step description of how to arrive at a solution to a given problem
