A program is a set of commands or commands to be dead by the computing machine to set up more than a few favour. A system of rules involves symbols for finding a puzzle and too satisfactory confirmation which would be a line to everyone who tries to grasp the system.
An algorithmic program is a formula, a method, a recipe, a footfall by footfall ceremony to be followed in command to pick up the mixture to a inhibition.
Conversion of an formula to a programme in a programing linguistic communication pursuing the syntax and semantics of that vernacular is characterised as a codification.
Syntax is the correct device or sentence structure of letters a command or progression of commands which are pre-defines by that precise planning tongue. Semantics is the diagnostic characterization of a programme or set of commands, removed from the grammatic skeleton. The machine detects structure errors but does not discover rational errors.
What are the Criteria for a not bad program?
- It should be correct i.e. production should be as per the specifications
- It should be reliable; it should control accurately for a womb-to-tomb length of instance and besides drive truly finished all ranges and coupling of data.
- It should be robust; unclaimed inputs or accumulation should be identified and becoming defect phone call should be flashed. It should never write off.
- It should be user friendly with decent comments, tips, on-line support and fleeting cut options.
- It should be efficient, with token memory and quality output in unexceptionable incident duration.
- It should be readable i.e. it should be clear-cut so that it can be hidden to engineer changes and intensify it if required.
- It should be portable so that system can be dead on opposite machines and environment.
- It should tail all standards and have proper certification.
