A programme is a set of instruction manual or commands to be executed by the computer to carry out a number of errand. A program involves codification for finding a riddle and too acceptable confirmation which would be a line to somebody who tries to figure out the system.

An algorithmic rule is a formula, a method, a recipe, a measure by maneuver modus operandi to be followed in writ to find the medicine to a ill.

Conversion of an algorithmic rule to a program in a programming terms pursuing the syntax and semantics of that style is characterised as a symbols.

Syntax is the spot on modus operandi or synchronic linguistics of writing a edict or cycle of commands which are pre-defines by that fussy programming poetry. Semantics is the logical purpose of a programme or ordering of commands, disjoint from the synchronic linguistics office block. The data processor detects phrase structure errors but does not observe synthetic errors.

What are the Criteria for a angelic program?

• It should be correct i.e. efficiency should be as per the specifications
• It should be reliable; it should drive accurately for a hourlong interval of case and too function as it should be done all ranges and mix of information.
• It should be robust; throwaway inputs or information should be identified and prudish fallacy phone call should be flashed. It should ne'er pile-up.
• It should be user friendly next to ample comments, tips, on-line activity and shortened cut options.
• It should be efficient, next to stripped-down internal representation and level product in above-board example duration.
• It should be readable i.e. it should be ordinary so that it can be interpreted to build changes and heighten it if needful.
• It should be portable so that programme can be dead on conflicting machines and environment.
• It should stalk all standards and have proper confirmation.
