Real Life Algorithms Overview: Apžvalga
Algorithms are precise step-by-step instructions on how to accomplish a desired task. A formal algorithm for use with computers or in mathematics must be very detailed and resolve the ambiguities that we take for granted in everyday life. Your first out of class assignment is to pick a common or interesting task and approach it algorithmically, breaking it down to the level that a computer might understand.
Assignment:Užduotis
Sukurti konsolinę programą C/C++ ar kita programavimo kalba ir įgyvendinti unikalų realaus gyvenimo algoritmą. Žemiau pateiktą pavyzdį naudoti tik kaip šabloną. Temą privalote sugalvoti patys.
- Aprašyti sugalvotą algoritmą pseudokodu bei nubrėžti šio algoritmo blokinę schemą.
- Įvertinti ir realizuoti išimtis, kurios gali nulemti jūsų algortimo veikimą neteisingai.
- Realizuoti įvedimą iš klaviatūros ir priklausomai nuo pasirinkto punkto algortimo baigtis turi būti skirtinga.
For this project you need to pick an everyday or interesting task and create an algorithm that explains how to do it.
- You need to specify what (if anything) is input (like ingredients in a recipe);
- The process by which you operate on that input to produce or accomplish a task;
- What the output of the algorithm is;
- What (if any) assumptions are made in the algorithm.

Example: Pavyzdys
Algorithm: Calling a friend on the telephone
Input: The telephone number of your friend.
Output: None
Steps: Žingsniai
- Pick up the phone and listen for a dial tone
- Press each digit of the phone number on the phone
- If busy, hang up phone, wait 5 minutes, jump to step 2
- If no one answers, leave a message then hang up
- If no answering machine, hang up and wait 2 hours, then jump to step 2
- Talk to friend
- Hang up phone
- Step 1 assumes that you live alone and no one else could be on the phone.
- The algorithm assumes the existence of a working phone and active service.
- The algorithm assumes you are not deaf or mute.
- The algorithm assumes a normal corded phone.
