Structured programming

Structured programming yog lub feem ntau loj ua ntej nyob rau hauv koj daim teb no thaum lub caij. Txawm tias muaj tseeb hais tias yuav luag tag nrho cov muaj ib tug general lub tswv yim ntawm nws, yuav luag tsis muaj ib tug yuav muab ib tug meej thiab tseeb ntsiab txhais ntawm no lub sij hawm. Structured programming txo nws hwj lub hom phiaj tseem ceeb ntawm kev sau ntawv qhov tsawg tshaj plaws kev pab cuam complexity, yuam programmer xav kom meej meej, yooj yim lub xaav ntawm qhov kev pab cuam. Cov ntawv nyeem yuav tsum tau ua kom nws nyeem los ntawm sab saum toj mus rau nram qab. Qhov no mob yog ua txhaum yog tias nyob rau hauv lub code muaj tswv mus, vim hais tias lawv ua txhaum cov qauv ntawm tag nrho ntev ntawm qhov kev pab cuam. Txawm tias muaj tseeb hais tias qhov no daim duab yuav tsis muab suav hais tias lub feem ntau yooj yim, koj yuav tseem hais tias lub hav zoov ntawm cov code ntawm tus neeg tsav tsheb yog lub feem ntau eye-catching qauv hom kev ua txhaum. Lub cev modules thiab siv yooj yim lug yuav tsum yog resistant rau kev kho vajtse tsis ua hauj lwm, uas tsis nyob rau hauv cov kev pab cuam thiab distortions ntawm qhov cov ntaub ntawv.

Cov yooj yim hauv paus ntsiab lus ntawm cob programming yog raws li nram no. Tej kev pab cuam yuav tsum nkag tsim rau lub hauv paus ntawm lub elementary lug ntawm peb tej hom:

- yooj yim ib theem zuj zus;

- tej yam kev mob los yog lwm cov kev;

- repetition, piv txwv li mus thiab iterations.

Yuav siv tau ib los yog ob tug ntawm txhua yam nyob rau tib lub sij hawm. Txhua zaug xwb qauv xam qhovkev feature - tus tsuas yog hloov lwm lub tsev ntawm kev tswj taw tes nyob rau hauv cov qauv thiab ib tug taw tes ntawm nkag mus rau hauv lub tsev. Qhov no hom ntawm kev tsim kho muaj ib tug disciplining thiab systematizing nqi.

Lub simplicity ntawm tus thawj lug nyob rau hauv lub structured programming tiv thaiv ntaub ntawv mus, thiab intricate tswj iav. Lub complexity ntawm qhov kev pab cuam yog significantly txo nrog ua structuring ntawm modules tsub kom lawv visibility, thiab qhov no yuav pab kom txo tau cov naj npawb ntawm cov uas tsis. Txawm li cas los, muaj kuj yog ib tug tsis muaj structuring - rau txoj kev zoo nkauj thiab clarity ntawm cov cai uas koj yuav tau them ntxiv nco, raws li zoo raws li lub sij hawm uas yuav tsum tau siv lawv nyob rau ib lub computer.

Structured programming, piv txwv li lub structuring ntawm software ntawv lawv tus kheej, yog nkaus nyob rau dab tsi yog siv rau cov lus no. Ntawm cov hoob kawm, rau lo lus nug tshwm sim, uas lawv yog qhov zoo tshaj plaws suited. Niaj hnub nimno software txoj kev loj hlob yam cuab yeej uas xam tau tias yog qhov zoo tshaj plaws cov lus, siv ib structured mus kom ze rau lub cajmeem. Ntawm cov feem ntau muaj peev xwm yuav qhia tau Basic, Pascal thiab FoxBASE. Piv txwv li, nyob rau hauv lub rooj sib txoos yuav lus yog yuav luag tsis yooj yim sua los mus siv rau hauv lub hauv paus ntsiab lus embodied nyob rau hauv lub tswvyim ntawm cob programming. Qhov no lus yog teem rau kev sau ntawv software ntawm ib tug tsawg theem code.

Structured programming no yeej teem rau lub sis raug zoo nrog cov neeg, tsis nrog cov cav tov, li ntawd, conducive mus sau ntawv cov kev pab cuam uas muaj tseeb thiab yooj yim daws mus rau qhov teeb meem. Lub programmer yuav tsum xav hais tias nyob rau hauv cov nqe lus ntawm qhov yooj yim ntxwv designs.

Yog hais tias peb tham txog txoj hauj lwm tus txheeb ze mus rau lub yav tas los hais cov lus mus rau, ces nws yuav tsum tau zam rau siv, peb txog qhov twg ua tau, tab sis nws yuav tsum nyob rau hauv tsis muaj txoj kev cuam tshuam rau cov clarity ntawm qhov kev pab cuam. Tej zaum siv no neeg teb xov tooj yog tsuas yuav tsum tau mus tawm los ntawm ib co ya ntawm qhov kev pab cuam los yog kev voj voog, raws li zoo raws li kom tsis txhob cov tsos ntawm ib yam nkaus thiab-qhov tob tib rab diav rawg, Ntxiv, hais tias cov kev hloov yog txuam nrog ib tug tsawg dua theem ntawm cov kev pab cuam. Nyob rau hauv qhov kev pab cuam qauv thiab yog yooj yim tshwmsim los ntawm sab saum toj mus rau nram qab. Qhov phem tshaj kev xaiv ntawm kev siv no neeg teb xov tooj yog txuam nrog rau cov kev hloov los ntawm lub hauv qab li.

Yuav kom pab txhawb kev nyeem ntawv ntawm qhov kev pab cuam feem ntau ntxiv dawb paug kab nruab nrab ntawm khej. Tsim sau ntawv pab cuam ntawv nrog translations, yog li ntawd koj yuav tau nyeem cov theem zuj zus thiab tus naj npawb ntawm attachments.
