Nruas-taw qhia kom paub programming

Nruas-taw qhia kom paub programming - ib txoj kev raws li nyob ze li sai tau mus rau peb cov coj tus cwj pwm. Nws ua hauj lwm pab raws li ib tug natural extension ntawm ua ntej lawm nrhav muaj feem xyuam rau txoj kev loj hlob ntawm lub cajmeem lus. Yog hais tias peb tham txog cob programming, ces qhov no coj yog ntau npaum li cas structured tshaj lub ua ntej lawm version, nyob rau hauv tas li ntawd, nws yog ntau paub daws teeb, ntau modular. Peb twb tau npaj siab mus disengage thiab tsiv mus nyob rau lub cajmeem ntsiab ntawm lub thiaj li hu ua nrog theem.

Nruas-taw qhia kom paub programming yog siv rau txoj kev loj hlob ntawm tshwj xeeb cov lus. Lawv feem ntau yog yus muaj los ntawm peb lub ntsiab nta:

- encapsulation, piv txwv li lub ua ke ntawm cov ntaub ntawv nrog rau cov kev khiav dej num thiab cov txheej txheem, raws li zoo raws li manipulating cov ntaub ntawv cov ntaub ntawv teb, txoj kev ua ib tug nkaus tshiab ntawm database, hu ua tus kwv;

- qub txeeg qub teg, cov kwv txhais implying nws tom ntej siv los tsim kom tau ib tug hierarchy ntawm cov khoom tsim muaj lub peev xwm los tsim tshiab khoom uas nyob hauv lub hierarchy, raws li zoo raws li implying saib code thiab tsim ntaub ntawv hais txog tag nrho cov khoom;

- polymorphism, uas yog, muaj peev xwm muab cov kev ua ntawm lub tib lub npe, uas yuav ces yuav muab qhia thiab nce thiab nqis tus kwv hierarchy, thiab cov nyob qib siab ntawm txhua tus kwv kev siv ntawm qhov kev txiav txim nyob rau hauv no txoj kev yuav tsum tau cov luag hauj lwm uas yog txoj cai rau nws.

Nruas-taw qhia kom paub programming Delphi muab ib tug ua tiav set ntawm cov cuab yeej rau programming, cov uas yog: ntau dua modularity thiab xyaum paub daws teeb, lub built-in muaj peev xwm rov siv. Tag nrho cov yam ntxwv yuav tsum tau ntaus nqi rau tus code, uas yog ntau structured, ntau yooj yim nyob rau hauv cov nqe lus ntawm cov kev pab thiab ntau npaum li cas saj zawg zog. Heev feem ntau, cov kwv-taw qhia kom paub programming ua rau peb tawm ib sab qhov kev txiav txim hais txog programming rau ntau xyoo ntshai li tus txheej txheem. Txawm li cas los, thaum zoo li no yog ua li cas, tus txheej txheem ntawm txoj kev loj hlob tsis zoo li nyuab, thiab nkawd ib tug ntshiab thiab ib qho zoo heev lub cuab tam rau ib tug ntau yam ntawm kev pab raws qib, delivering loj loj teeb meem tseem ceeb software.

Yog hais tias koj tau ua nws peb ua hauj lwm, piv txwv li, mus kawm cov kwv-taw qhia kom paub programming nyob rau hauv PHP, nws yog tsim nyog los muab pov tseg thiab tsis nco qab dab tsi koj paub txog nws ua ntej, thiab tuaj mus rau nws txoj kev kawm nrog ib tug huv slate. Tib txoj kev koj yuav tau mus saib tag nrho cov ntsiab lus ntawm no mus kom ze rau soj ntsuam nws cov usability thiab nta. Nruas-taw qhia kom paub programming tsis yog txoj kev, nws yog ntau zoo li ib tug pab tswv yim teem rau compiling huv code. Lub compiler sau rau ntau yam ntsiab cai, yog hais tias peb los sib piv nws nrog rau cov neeg txhais lus, thaum nws ceev yog ntau dua. Compilers yog aimed ntawm txoj kev loj hlob ntawm tej npaj software khoom, tsis txhob ib tug tsawg ntau yam kev pab raws qib.

cov chav kawm

Ua ntej nws tau tsim yam khoom-taw qhia kom paub programming lus nyob rau hauv ntau uas tau brewing qhov yuav tsum tau rau ncua cov ntaub ntawv hom tshaj tiag tiag thiab integer xov tooj, phau ntawv ntau yam thiab Boolean zog. Nws yuav tsis yooj yim mus ua hauj lwm nrog integer cov ntaub ntawv arrays. Hais tias yog dab tsi siv cov chav kawm ntawv nyob rau hauv OOP tswv yim. Nrog xws lug ua yooj yim npaum li mus ua hauj lwm nrog, vim hais tias tam sim no rau cov tib khoom tsis tas yuav sau npe ib tug ntau ntawm cov kab ntawm code kom tau ib yam dab tsi uas yuav tsum generated tau. Rau cov uas tsis-theem programming lus xws li ib tug txoj kev rau nkawd yuav tsum nyuaj heev, tab sis nyob rau ib lub tshiab rau theem ntawm kev loj hlob mus siv nws heev zoo.
