Isingeniso solimi lwe-C++: Umhlahlandlela Wokugcina

Informatec Digital » Ukuhlela » Isingeniso solimi lwe-C++: Umhlahlandlela Wokugcina

I-C++ ingolunye lwezilimi zokuhlela ezinethonya kakhulu futhi ezisetshenziswa kabanzi emhlabeni wokuthuthukiswa kwesoftware. Kusukela yaqalwa kuze kube namuhla, isiguquke yaba ithuluzi elinamandla nelisebenza ngezindlela eziningi elivumela abahleli bezinhlelo ukuthi bakhe izinhlelo zokusebenza ezisebenza kahle nezisebenza kahle kakhulu. Kulesi sihloko sizovakashela Isingeniso solimi lwe-C++ ngendlela eqinile.

Isingeniso solimi lwe-C++

Yini i-C++?

I-C++ ulimi lokuhlela olunenhloso ejwayelekile oluhlanganisa izici zokuhlela ezisezingeni eliphansi nezisezingeni eliphezulu. Yaklanywa njengesandiso solimi lwe -C , yengeza imisebenzi emisha efana nokuhlela okuqondiswe ezintweni. Ukuguquguquka kwayo kwenza kube kuhle kakhulu ekuthuthukiseni yonke into kusukela ezinhlelweni zokusebenza kuya emidlalweni yevidiyo.

Umlando nokuziphendukela kwemvelo

Umlando we-C++ uqala emuva ngo-1979, lapho uBjarne Stroustrup eqala ukusebenza kulokho akubiza ngokuthi "i-C enamakilasi." Umgomo wakhe kwakuwukuthuthukisa i-C ngokungeza izici ezivela kwezinye izilimi , njenge-Simula. Ngo-1983, lolu limi lwaqanjwa kabusha ngokuthi i-C++, futhi kusukela ngaleso sikhathi luye lwabhekana nokubuyekezwa kanye nezindinganiso eziningana, kanti i-C++20 iyinguqulo yakamuva kakhulu ngesikhathi sokubhala.

C++ Okuyisisekelo

Ukuqala ukuhlela ku-C++, kubalulekile ukuqonda imiqondo yayo eyisisekelo. Ake sibheke izinto ezibalulekile ezakha isisekelo salolu limi.

I-syntax eyisisekelo

I-syntax ye-C++ ifana ne-C, kodwa inezengezo ezithile ezibalulekile. Uhlelo olujwayelekile lwe-C++ luqala ngokufakwa kwemitapo yolwazi edingekayo, kulandelwe umsebenzi main(), okuyindawo yokungena yohlelo. Ngokwesibonelo:

#include <iostream>

int main() {
    std::cout << "¡Hola, mundo!" << std::endl;
    return 0;
}

Lolu hlelo olulula lubonisa okwakudala "Sawubona, mhlaba!" esikrinini.

Izinhlobo zedatha neziguquguqukayo

I-C++ inikezela ngezinhlobo eziningi zedatha, okuhlanganisa:

• Inombolo ephelele (int)
• Izinombolo zamaphoyinti antantayo (float, double)
• Izinhlamvu (char)
• I-Booleans (bool)
• I-Arrays
• Izikhombo

Okuguquguqukayo kumenyezelwa ngokucacisa uhlobo lwedatha olulandelwa igama eliguquguqukayo. Ngokwesibonelo:

int edad = 25;
float altura = 1.75;
char inicial = 'A';
bool esEstudiante = true;

Izakhiwo zokulawula

Izakhiwo zokulawula zibalulekile kunoma yiluphi ulimi lokuhlela, futhi i-C++ injalo. Lokhu kusivumela ukuthi silawule ukusebenza kwezinhlelo zethu.

Imibandela

Izakhiwo ezinemibandela zisivumela ukuthi sisebenzise amabhlogo ahlukene wekhodi kuye ngezimo ezithile. Okuvame kakhulu kukhona if,

else if y else. Isibonelo:

int edad = 18;

if (edad >= 18) {
    std::cout << "Eres mayor de edad" << std::endl;
} else {
    std::cout << "Eres menor de edad" << std::endl;
}

Izihibe

Amaluphu asivumela ukuthi siphinde ibhulokhi yekhodi izikhathi eziningi. I-C++ inikeza izinhlobo ezimbalwa zamalophu:

1. ngoba: Kuhle uma sazi inani eliqondile lokuphindaphinda.
2. ngenkathi: Isebenzisa inqobo nje uma isimo siyiqiniso.
3. yenza-ngenkathi: Kufana nesikhathi, kodwa kuqinisekisa okungenani ukubulawa okukodwa.

Isibonelo se-loop:

for (int i = 0; i < 5; i++) {
    std::cout << i << " ";
}
// Salida: 0 1 2 3 4

Imisebenzi ku-C++

Imisebenzi amabhulokhi ekhodi asebenziseka kabusha enza imisebenzi ethile. Zibalulekile ukuhlela nokuhlela izinhlelo zethu.

Isimemezelo nencazelo

Ku-C++, ngokuvamile simemezela imisebenzi kumafayela anhlokweni (.h) futhi siwachaze kumafayela okusetshenziswa (.cpp). Isimemezelo somsebenzi sihlanganisa igama lawo, uhlobo lokubuyisela, namapharamitha, kuyilapho incazelo ihlanganisa nomzimba womsebenzi.

// Declaración (en archivo .h)
int sumar(int a, int b);

// Definición (en archivo .cpp)
int sumar(int a, int b) {
    return a + b;
}

Amapharamitha adlulayo

I-C++ ikuvumela ukuthi udlulise amapharamitha emisebenzini ngezindlela ezahlukene:

1. Ngenani: Ikhophi yengxabano idaliwe.
2. Ukuze uthole ireferensi: Ikheli lenkumbulo yengxabano lidlulisiwe.
3. Nge-pointer: Kufana nereferensi, kodwa kuvumelana nezimo.

Isibonelo sokudlula ngereferensi:

void incrementar(int &numero) {
    numero++;
}

int main() {
    int x = 5;
    incrementar(x);
    std::cout << x; // Salida: 6
    return 0;
}

Izinhlelo eziqondiswe entweni

Esinye sezici ezinamandla kakhulu ze-C++ ukusekelwa kwayo kwezinhlelo ezigxile ezintweni (OOP). Le paradigm isivumela ukuthi sihlele ikhodi yethu ibe izakhiwo ezibizwa ngokuthi amakilasi, ahlanganisa idatha ehlobene nokuziphatha.

Amakilasi nezinto

Ikilasi yisifanekiso sokudala izinto. Ichaza izici (izibaluli) nokuziphatha (izindlela) izinto zalelo klasi ezizoba nazo. Ngokwesibonelo:

class Persona {
private:
    std::string nombre;
    int edad;

public:
    Persona(std::string n, int e) : nombre(n), edad(e) {}

    void saludar() {
        std::cout << "Hola, soy " << nombre << " y tengo " << edad << " años." << std::endl;
    }
};

int main() {
    Persona p1("Ana", 25);
    p1.saludar(); // Salida: Hola, soy Ana y tengo 25 años.
    return 0;
}

Ifa kanye ne-polymorphism

Ifa likuvumela ukuthi udale amakilasi amasha ngokusekelwe kumakilasi akhona, uzuze izimfanelo nezindlela zawo. I-Polymorphism, ngakolunye uhlangothi, isivumela ukuthi sisebenzise isixhumi esibonakalayo esivamile sezinhlobo ezahlukene zedatha.

class Estudiante : public Persona {
private:
    std::string carrera;

public:
    Estudiante(std::string n, int e, std::string c) : Persona(n, e), carrera(c) {}

    void estudiar() {
        std::cout << "Estoy estudiando " << carrera << std::endl;
    }
};

Ukuphathwa kwememori

I-C++ inikezela ngokulawula okunomphumela omuhle ekulawuleni inkumbulo, okuvumela izinhlelo ezisebenza kahle kakhulu kodwa futhi kudinga ukunakekelwa okwengeziwe ngasohlangothini lomhleli.

Izikhombo

Izikhombisi ziyizinto eziguquguqukayo ezigcina amakheli ememori. Ziyithuluzi elinamandla kodwa futhi ziwumthombo ovamile wamaphutha uma zingasetshenziswa ngendlela efanele.

int x = 5;
int *ptr = &x;
std::cout << *ptr; // Salida: 5

Ukwabiwa okunamandla

I-C++ ivumela inkumbulo ukuthi yabiwe ngokuguquguqukayo ngesikhathi sokwenziwa kohlelo. Lokhu kuyasiza uma singazi kusengaphambili ukuthi sizodinga inkumbulo engakanani.

int *arr = new int[10]; // Asigna un array de 10 enteros
// ... usar el array ...
delete[] arr; // Liberar la memoria cuando ya no se necesita

Imitapo yolwazi ejwayelekile

I-C++ iza nomtapo wezincwadi ojwayelekile ocebile ohlinzeka ngemisebenzi eminingi ewusizo.

umabhebhana

Lo mtapo wolwazi uhlinzeka ngokusebenza kwe- okokufaka nokukhiphayo yedatha. Izinto cin y cout ziwusizo ikakhulukazi:

#include <iostream>

int main() {
    int numero;
    std::cout << "Introduce un número: ";
    std::cin >> numero;
    std::cout << "Has introducido: " << numero << std::endl;
    return 0;
}

i-vector nentambo

vector iwukusebenzisa amalungu afanayo ashukumisayo, kuyilapho string iyikilasi lokuphatha iyunithi yezinhlamvu zombhalo kalula kakhulu kunezinhlu zezinhlamvu ezijwayelekile.

#include <vector>
#include <string>

std::vector<int> numeros = {1, 2, 3, 4, 5};
std::string saludo = "Hola, mundo!";

Ukuphathwa okungafani

Ukuphatha okuhlukile kuyindlela yokusingatha amaphutha nezimo ezingalindelekile ezinhlelweni zethu.

Zama, bamba bese uphonsa

Sisebenzisa try ukugoqa ikhodi engase ikhiphe okuhlukile, catch ukubamba nokuphatha okuhlukile, futhi throw ukuphonsa okuhlukile.

#include <stdexcept>

try {
    int resultado = dividir(10, 0);
} catch (const std::runtime_error& e) {
    std::cerr << "Error: " << e.what() << std::endl;
}

Izifanekiso

Amathempulethi ayisici esinamandla se-C++ esikuvumela ukuthi ubhale ikhodi ejwayelekile esebenza nezinhlobo ezahlukene zedatha.

Imisebenzi Yesifanekiso

Umsebenzi wesifanekiso ungasebenza nezinhlobo eziningi zedatha:

template <typename T>
T maximo(T a, T b) {
    return (a > b) ? a : b;
}

int main() {
    std::cout << maximo(3, 7) << std::endl;     // Salida: 7
    std::cout << maximo(3.14, 2.72) << std::endl; // Salida: 3.14
    return 0;
}

Amakilasi ezifanekiso

Ngokufana nemisebenzi yesifanekiso, singakha amakilasi asebenza ngezinhlobo ezijwayelekile:

template <typename T>
class Contenedor {
private:
    T elemento;
public:
    void setElemento(T e) { elemento = e; }
    T getElemento() { return elemento; }
};

Imikhuba emihle yokuhlela

Ukwamukela izinqubo ezinhle zokuhlela kubalulekile ekubhaleni ikhodi yekhwalithi ye-C++.

Isitayela sokubhala amakhodi

Ukugcina isitayela sekhodi esingaguquki kuthuthukisa ukufundeka kwekhodi. Ezinye izincomo:

• Sebenzisa amagama achazayo kuma-variables nemisebenzi.
• Gcina ukuhlehlisa okungaguquki.
• Ikhodi yokubeka amazwana uma kudingeka.

Ukusebenziseka

I-C++ ivumela izinga eliphezulu lokwenza kahle. Amanye amasu ahlanganisa:

• Sebenzisa izinkomba esikhundleni samakhophi noma nini lapho kunokwenzeka.
• Gwema ukudalwa okungadingekile kwezinto zesikhashana.
• Sebenzisa izakhiwo zedatha ezifanele kumsebenzi ngamunye.

Amathuluzi entuthuko

Ukuze uhlele kahle ku-C++, kubalulekile ukuba namathuluzi afanele.
