         Tugas program minggu ke 9

1)      Progra m  mencari elemen serta alamatnya ..

#include <iostream>

using namespace std;

int main(int argc, char *argv[])

{

int bil[3],i;

cout<<"elemen ke-1 ? "; cin>>bil[0];

cout<<"elemen ke-2 ? "; cin>>bil[0];

bil[1] = 5;

bil[2] = bil[1] + 8;

for(i=2;i<3;i++)

bil[i] = i*8;

bil[3] = bil[bil[1]];

for(i=0;i<7;i++)

cout<<"bil["<<i<<"] = "<<bil[i]<<" dan alamatnya: "<<&bil[i]<<"\n";

system("PAUSE");

    return EXIT_SUCCESS;

   

}

Nah…. Inilah hasil outputnya

TUGAS ALPROG 1 MINGGU (3 PROGRAM )

1)      Mencari luas dan keliling segi empat

#include <iostream.h>

#include <conio.h>

class segiempat {

        public :

         segiempat(float,float);

      segiempat(const segiempat&);

      ~segiempat();

      void cetak();

      float getluas() const;

      float getkeliling() const;

      keliling(const segiempat&);

   private :

           float pan,leb;

   };

int main () {

        float a,b;

   cout <<"masukkan panjang = ";

   cin >> a;

   cout <<"masukkan lebar      = ";

   cin >> b;

   cout <<endl;

        segiempat x(a,b);

   segiempat y=x;

   x.cetak();

   cout <<"luas             = "<<x.getluas()<<endl;

   cout <<"keliling       = "<<x.getkeliling()<<endl;

   cout <<"luas             = "<<y.getluas()<<endl;

   cout <<"keliling       = "<<y.getkeliling()<<endl;

   getch();

        return 0;

}

segiempat::segiempat(float panjang, float lebar){

   pan=panjang;

   leb=lebar;

}

float segiempat::getluas() const{

   return (pan*leb);

        }

float segiempat::getkeliling() const{

   return 2*(pan+leb);

        }

segiempat::~segiempat(){

        cout << "party caaaantikk";

        }

segiempat::segiempat(const segiempat& s){

   pan=s.pan;

   leb=s.leb;

        }

void segiempat::cetak(){

   cout<<"panjang\t= "<<pan<<endl;

   cout<<"lebar\t= "<<leb<<endl;

   getch();

        }

1)      Menghitung nilai tukar (temp) nilai yang besar berada di sebelah kiri…

#include <iostream.h>

#include <conio.h>

class tukar{

        friend ostream& operator << (ostream& , tukar& );

        friend istream& operator >> (istream& , tukar& );

public:

        tukar();

        void penukaran();

private:

        int a, b, temp;

};

tukar::tukar(){}

istream& operator >> (istream& in, tukar& t){

        cout<<"masukkan nilai a : "; in>>t.a;

        cout<<"masukkan nilai b : "; in>>t.b;

return in;

}

void tukar::penukaran(){

        temp = a;

        a = b;

        b = temp;

}

ostream& operator << (ostream& out, tukar& t){

        out<<"nilai a: "<<t.a<<endl;

        out<<"nilai b: "<<t.b<<endl;

        getch();

return out;

}

void main(){

        tukar k;

        cin>>k;

        k.penukaran();

        cout<<k;

        getch();

}

3)menghitung nilai fungsi x

#include <iostream.h>

#include <conio.h>

class fungsi{

        friend ostream& operator << (ostream& , fungsi& );

        friend istream& operator >> (istream& , fungsi& );

public:

        fungsi();

        int pingan();

private:

        int x, y;

};

fungsi::fungsi(){

cout<<"fungsi f(x)=x+5 \n";

}

istream& operator >> (istream& in, fungsi& t){

        cout<<"masukkan nilai x : "; in>>t.x;

return in;

}

int fungsi::pingan(){

        return (x+5);

}

ostream& operator << (ostream& out, fungsi& t){

        out<<"nilai f(x) : "<<t.pingan()<<endl;

return out;

}

int main(){

        fungsi k;

        cin>>k;

        cout << k;

        getch();

}
