Algorithm vs Pseudocode
Ib qho algorithm tsuas yog kev daws teeb meem. Ib qho algorithm nthuav qhia cov kev daws teeb meem rau ib qho teeb meem raws li cov txheej txheem los yog cov lus qhia zoo. Pseudo-code yog ib txoj hauv kev piav qhia txog algorithm. Pseudo-code tsis siv cov syntax ntawm cov lus programming tshwj xeeb, yog li tsis tuaj yeem ua tiav ntawm lub computer. Tab sis nws zoo ib yam li cov qauv ntawm cov lus programming thiab muaj cov ntsiab lus zoo ib yam.
Algorithm
Ib qho algorithm muab kev daws teeb meem rau ib qho teeb meem tshwj xeeb raws li cov kauj ruam tau piav qhia zoo. Ib daim ntawv qhia hauv phau ntawv ua noj yog ib qho piv txwv zoo ntawm cov algorithm. Thaum lub khoos phis tawj siv los daws qhov teeb meem tshwj xeeb, cov kauj ruam rau kev daws yuav tsum tau sib txuas lus rau lub khoos phis tawj. Qhov no ua rau kev kawm ntawm algorithms yog ib feem tseem ceeb hauv computer science. Ib qho algorithm raug tua nyob rau hauv lub computer los ntawm kev sib txuas ntau ntawm cov haujlwm tseem ceeb xws li ntxiv thiab rho tawm los ua cov haujlwm ua lej nyuaj. Tab sis txhais lub tswv yim ntawm algorithm rau hauv computer code tsis ncaj nraim rau pem hauv ntej. Tshwj xeeb, hloov cov algorithm rau hauv cov lus qis xws li cov lus sib dhos tuaj yeem yog qhov nyuaj heev dua li siv cov lus siab xws li C lossis Java. Thaum tsim ib qho algorithm, nws yog ib qho tseem ceeb uas yuav tsum tau ua qhov kev ntsuam xyuas ntawm cov peev txheej (xws li lub sijhawm thiab kev cia khoom) uas yuav tsum tau ua los ntawm algorithm. Cov ntawv sau xws li cov cim O loj yog siv los ua lub sijhawm thiab khaws cia ntawm cov algorithms. Algorithms tuaj yeem qhia tau siv cov lus ntuj, pseudocode, flowcharts, thiab lwm yam.
Pseudocode
Pseudocode yog ib txoj hauv kev uas tuaj yeem siv los sawv cev rau algorithm. Nws tsis yog sau nyob rau hauv ib tug tshwj xeeb syntax uas yog siv los ntawm ib tug programming lus thiab yog li ntawd tsis tuaj yeem ua rau hauv lub computer. Muaj ntau ntau hom ntawv siv rau kev sau ntawv pseudocodes thiab feem ntau ntawm lawv qiv qee cov qauv los ntawm cov lus programming nrov xws li C, Lisp, FORTRAN, thiab lwm yam. Tsis tas li ntawd, cov lus ntuj siv thaum nthuav qhia cov ntsiab lus uas tsis tseem ceeb. Feem ntau ntawm cov algorithms tau nthuav tawm siv pseudocode vim lawv tuaj yeem nyeem thiab nkag siab siv cov programmers uas paub txog cov lus sib txawv. Qee hom lus xws li Pascal muaj cov syntax uas zoo ib yam li pseudocode ua rau kev hloov pauv ntawm pseudocode mus rau cov txheej txheem sib txuas lus yooj yim dua. Pseudocode tso cai rau suav nrog cov kev tswj hwm xws li THAUM, YOG-TAM SIM NO, REPEAT-UNTIL, RAU, thiab CASE, uas muaj nyob hauv ntau hom lus siab.
Qhov txawv ntawm Algorithm thiab Pseudocode yog dab tsi?
Ib qho algorithm yog ib qho kev txiav txim zoo ntawm cov kauj ruam uas muab kev daws teeb meem rau ib qho teeb meem, thaum lub pseudocode yog ib txoj hauv kev uas tuaj yeem siv los sawv cev rau ib qho algorithm. Thaum cov algorithms tuaj yeem sau ua hom lus, pseudocode yog sau rau hauv ib hom ntawv uas muaj feem xyuam nrog cov txheej txheem kev ua haujlwm siab. Tab sis pseudocode tsis siv cov lus programming lus syntax thiab yog li ntawd tuaj yeem nkag siab los ntawm cov programmer uas paub txog cov lus sib txawv. Tsis tas li ntawd, hloov cov algorithm uas tau nthuav tawm hauv pseudocode rau programming code yuav yooj yim dua li hloov cov algorithm sau ua lus ntuj.
