Qhov Tseem Ceeb Qhov Sib Txawv - Cov Ntaub Ntawv Header vs Cov Tsev Qiv Ntawv
Cov lus programming xws li C thiab C ++ muaj cov ntaub ntawv header thiab cov ntaub ntawv qiv. Cov lus no khaws qhov tsis tu ncua thiab ua haujlwm prototypes hauv cov ntaub ntawv header. Tus programmer tuaj yeem sau cov ntaub ntawv header ntawm nws tus kheej lossis lawv tuaj nrog lub compiler. Header cov ntaub ntawv muaj txiaj ntsig zoo vim lawv ua rau qhov kev zov me nyuam muaj kev txhim kho thiab tswj tau. Yog tias tag nrho cov haujlwm tau hais tseg nyob rau hauv tib cov ntaub ntawv, nws ua rau qhov kev pab cuam complex. Yog li, tus programmer tuaj yeem suav nrog cov ntaub ntawv header xav tau thaum sau qhov program. Cov ntaub ntawv header muaj cov lus tshaj tawm ua haujlwm. Cov lus tshaj tawm no qhia tus neeg sau txog lub npe ua haujlwm, rov qab hom thiab tsis muaj. Cov ntaub ntawv hauv tsev qiv ntawv muaj qhov kev siv tiag tiag ntawm cov haujlwm tshaj tawm hauv cov ntaub ntawv header. C lub tsev qiv ntawv thiab C ++ tsev qiv ntawv yog cov tsev qiv ntawv cov ntaub ntawv. Yog li ntawd, qhov sib txawv tseem ceeb ntawm cov ntaub ntawv header thiab cov tsev qiv ntawv cov ntaub ntawv yog cov ntaub ntawv header muaj cov lus tshaj tawm ua haujlwm kom sib koom ntawm ntau cov ntaub ntawv thaum lub tsev qiv ntawv cov ntaub ntawv yog cov ntaub ntawv uas muaj cov ntsiab lus ua haujlwm rau cov haujlwm tshaj tawm hauv cov ntaub ntawv header.
Header File yog dab tsi?
A Header file muaj cov lus tshaj tawm ua haujlwm. Tus programmer tuaj yeem sau cov ntaub ntawv header lossis nws tuaj nrog lub compiler. Ib daim ntawv tshaj tawm qhia rau lub compiler txog lub npe ua haujlwm, rov qab hom thiab tsis muaj. Hauv C lus, cov ntaub ntawv header muaj.h extension. Cov ntaub ntawv header tau suav nrog hauv C program siv cov lus qhia ua ntej. Lub syntax ntawm kev ntxiv cov ntaub ntawv header hauv C los ntawm include. Yog tias tus programmer xav suav nrog cov ntaub ntawv lej lej, tuaj yeem sau nqe lussuav nrog.
Cov ntaub ntawv header muaj cov haujlwm uas tau teev tseg rau kev tawm tswv yim thiab tso tawm. Lub fclose yog siv los kaw cov kwj deg. Lub printf yog siv los xa cov ntaub ntawv tawm tswv yim rau cov qauv tso zis. Lub fscanf yog siv los nyeem cov tswv yim tawm tswv yim los ntawm cov tswv yim txheem. Cov ntaub ntawv header muaj cov haujlwm ntsig txog lub console. Lub getch yog siv los nyeem ib tug cim los ntawm lub console. Cov ntaub ntawv header muaj cov haujlwm muaj feem cuam tshuam rau txoj hlua manipulation. Lub strlen yog nrhiav qhov ntev ntawm txoj hlua. Txoj haujlwm strcmp yog los sib piv ob txoj hlua.
Cov haujlwm tsim nyog rau kev ua haujlwm duab kos tau suav nrog hauv cov ntaub ntawv header. Cov ntaub ntawv header muaj cov kev ua lej ntsig txog kev ua lej. Lub rand yog siv los tsim tus lej random. Txoj haujlwm pow yog siv los nrhiav lub zog ntawm tus lej. Qee qhov haujlwm ua lej yog sin, cos, tan, sqrt. Cov haujlwm no twb tau tshaj tawm hauv cov ntaub ntawv header.
suav nrog cov ntaub ntawv header hauv C ++ kuj zoo ib yam li C. Qhov ntawd kuj yog siv cov lus qhia ua ntej. Lub syntax ntawm kev ntxiv cov ntaub ntawv header hauv C ++ yog include. Yog tias tus programmer xav suav nrog iostream header cov ntaub ntawv, nws ua tiav siv include. Nws yog tus qauv input-output kwj tsev qiv ntawv. cin yog standard input kwj. Lub cout yog rau tus qauv tso zis kwj.
Daim duab 01: C program siv math.h thiab stdio.h header files
Nrog rau cov ntaub ntawv header zoo ib yam li luam thiab muab cov ntsiab lus ntawm cov ntaub ntawv header. Nws tuaj yeem ua yuam kev thiab tuaj yeem ua cov txheej txheem nyuaj yog tias muaj ntau cov ntaub ntawv. Ib yam li ntawd, cov ntaub ntawv header tuaj yeem suav nrog hauv cov haujlwm.
Cov Ntaub Ntawv Cov Ntaub Ntawv yog dab tsi?
Ib lub tsev qiv ntawv cov ntaub ntawv yuav muaj cov ntsiab lus ua haujlwm rau cov haujlwm tshaj tawm hauv cov ntaub ntawv header. Cov ntsiab lus ntawm kev ua haujlwm yog qhov tseeb ntawm kev ua haujlwm. Tus programmer siv cov haujlwm tshaj tawm hauv cov ntaub ntawv header hauv qhov program. Nws tsis yog tsim nyog los siv lawv los ntawm qhov pib. Thaum muab tso ua ke cov kev pab cuam, lub compiler pom cov ntsiab lus nyob rau hauv lub tsev qiv ntawv cov ntaub ntawv rau lub declared functions nyob rau hauv lub header ntaub ntawv.
Txawm hais tias cov ntaub ntawv header suav nrog hauv qhov program los ntawm tus programmer, cov ntaub ntawv hauv tsev qiv ntawv muaj feem cuam tshuam los ntawm lub compiler tau txais. Yog li ntawd, lub compiler siv lub tsev qiv ntawv cov ntaub ntawv los nrhiav cov kev siv tiag tiag ntawm cov haujlwm tshaj tawm hauv cov ntaub ntawv header. Yog tias printf() muaj nuj nqi siv nyob rau hauv qhov kev pab cuam, lub ntsiab txhais ntawm nws ua hauj lwm nyob rau hauv cov ntaub ntawv muaj feem xyuam rau lub tsev qiv ntawv. Yog math.h yog cov ntaub ntawv header, math.lib yog lub tsev qiv ntawv cov ntaub ntawv.
