Isihlanganisi se-C esiku-inthanethi – Sebenzisa C mahhala

Bhala, uhlanganise futhi usebenzise ikhodi ye-C mahhala kusiphequluli, ngaphandle kokufaka noma ukubhalisa. Faka i-stdin, ubone imiphumela namaphutha.

#include <stdio.h>
int main(void) { puts("Hello, world!"); return 0; }

Indlela yokusebenzisa umhlanganisi we-C ku-inthanethi

  1. Bhala noma unamathisele uhlelo lwe-C kusihleli. Qala ngohlelo olulula lwe-Hello World olunomsebenzi othi main.
  2. Uma uhlelo lufunda idatha, vula «Okufakwayo okujwayelekile» bese ufaka wonke amanani adingekayo ngaphambi kokuluqalisa.
  3. Chofoza «Qalisa» bese ubheka impendulo ku-«Umphumela». Uma ushintsha ikhodi noma idatha efakiwe, qalisa uhlelo futhi.

Ukulungiselela okufakwayo kwe-scanf ne-fgets

Lungiselela yonke idatha ngaphambi kokuqalisa. Uma ubiza scanf kabili nge-%d, faka u-3 no-4 uhlukanise ngesikhala; ku-fgets, hlukanisa imigqa yombhalo ngomugqa omusha. Kumodi yefu ezenzakalelayo, ikhodi nedatha efakiwe kuthunyelwa kusevisi ekude ukuze kuhlanganiswe futhi uhlelo lusebenze. Lena akuyona itheminali exoxisanayo: awukwazi ukufaka idatha entsha ngesikhathi uhlelo lusebenza.

Ngemva kokuba scanf ifunde nge-%d, uphawu lomugqa omusha lungasala kokufakiwe. Ngaleso sikhathi fgets ingafunda lolo phawu kuphela esikhundleni sombhalo olindelekile. Phatha uphawu olusele kukhodi ngaphambi kokufunda umugqa olandelayo.

Okufanele ukuhlole uma ukuhlanganisa kuhluleka

Funda umyalezo wokuqala wephutha lomhlanganisi bese uhlola inombolo yomugqa ekhonjisiwe. Hlola amasemikholoni, abakaki namagama eziguquguqukayo. Uma uhlelo lusebenza kodwa impendulo ingalungile, hlola idatha efakiwe nendlela ikhodi esebenza ngayo.
