How the use of constants rather than literals can simplify software maintenance.?
Say you put into your program the formula to calculate the area of a circle given its radius R asA = 3.141592 * R * R
Computer science teachers will usually mark you down for this, saying you should instead write it as
PI = 3.141592
...
A = PI * R * R
Because that way, should the value of pi ever change, you can just change it in the header and anywhere you've used the value in the program will automatically change with it.
Okay, that's not super likely, but suppose instead you had formulas to calculate the area of the circle, and the volume of a sphere, and the circumference of a circle, and the surface area of a sphere, and you run your program and notice that the answers you're getting are just slightly off what they should be. You look, and eventually find that the book you used to look up the value of pi had a typo and you've been using 3.145192 instead. Now you have to find everywhere it occurs in the program and fix it. If you had defined it in the header, you make the change in one spot, and its instantly fixed everywhere in the program.

What is software maintenance explain its types in software engin?
Software Maintenance : is the activity of modifying the software product after delivery ; in order to correct faults, improve performance and to improve other attributes ( attributes of a good software ) .Software maintenance is a vital element in SDLC . Normally and more often done by the developers / or software maintainers ( of the software service provider / the software company ) .Types of software maintenance : there were only three few years back, but present there are FOUR ( 4 ) types of software maintenance types / kinds are defined .Corrective Maintenance - corrective maintenance means a REACTIVE modification, done in the software product after the delivery . The purpose of corrective maintenance is to correct / or fix discovered ( or user reported ) problems in the system .Adaptive Maintenance - adaptive maintenance is also a modification done after delivery, in order to keep the software product usable in changing ( or changed ) environments / business environments . If this is not done properly by the time of change, business opportunities will be lost .Perfective Maintenance - a software should be efficient / less resource consuming / and should be easy to cope with . Perfective maintenance is done in order to improve the software performance ( after a change in the software or / the environment, the performance of the software changes ) . Also improving the maintainability is a concern .Preventive Maintenance - of course as it sounds, it's just PREVENTING . Preventive Maintenance is done, to detect and correct latent ( not developed ) faults before they become effective faults . This simply means the prevention of future problems .-------------------------------------------------------------------------------------------------EXTRA READING :Software maintenance sounds like, " ONLY ERROR CORRECTING ", but IT'S NOT that . 80% of the software maintenance is NON - CORRECTIVE activities ( activities which are not used to correct faults, but for other purposes ) . However, software maintenance issues can be seen in two perspectives, one is managerial issues and the other is technical issues . Managerial issues can be alignment with customer priorities, managing the staff, estimations . Technical issues may be limited understanding, impact analysis and testing .In software maintenance, SOFTWARE MAINTENANCE PLAN and SOFTWARE MAINTENANCE PROCESS are also KEY considerations . Software maintenance plan is the pre planning which should be very accurate ( this plan includes about user's requirement changes / or change requests, budget etc ) . Software maintenance process is the sequence of steps followed during the software maintenance process . which includes,Implementation ProcessProblem and modification analysis processProcess acceptance of the modificationThe migration processLast maintenance processetc ...----------------------------------------------------------------------------------------------------Hope you liked this article,CHEERS !Dileesha Mebox
