Contoh-contoh program array  :

  

1.     Jumlah bilangan

#include <iostream> using namespace std; int main ()                 { int n, i, A[100],j;                 cout<< "Masukan Bilangan N : ";                 cin>>n;                 for (i=0; i<n; i++)                 {                                 cout<< "Masukan Bilangan Ke "<< i+1 <<" : ";                                 cin >> A[i];                 }              for  (i=0; i<n; i++) {                 j = (n-1) - i;                 cout << "\ta[" << j <<"] = " << A[j]<< endl; } return 0; }

2   Menghitung Nilai rata2 dari Array

#include <iostream> using namespace std; int main () {                 int n, i, A[100], total=0;                 float rata2;                 cout<< "Masukan Nilai : ";                 cin>>n;                 for (i=0; i<n; i++)                 {                                 cout<< "Masukan Nilai ke "<< i+1 <<" : ";                                 cin>> A[i];                                 total=total + A[i];                 } rata2=total/n; cout << "maka rata2nya adalah : " << rata2 << endl; return 0; }

  

3.     Menghitung Frekuensi yang mucul di array

#include <iostream> using namespace std; int main () {                 int n, i, j, tot=0, A[100];                 cout << "Masukan Bilangan : ";                 cin>>n;                 for (i=0; i<n; i++)                 {                                 cout << "Masukan nilai ke "<< i+1 <<" : ";                                 cin>>A[i];                 }                 cout << "Masukan Angka yang akan di hitung frekuensinya : ";                 cin>> A[i];                 for (j=0; j<n; j++)                 {                                 if (A[j]==A[i])                                 {                                                 tot=tot+1;                                 }                 }                 cout<< "Maka Nilainya adalah :" <<tot;                 return 0; }

  

4.     Menghitung bilangan Genap dan Ganjil Dalam Array

#include <iostream> using namespace std; int main () {                                 int n, i, A[100];                                 cout << "Masukan berapa banyak bilangan :";                 cin>>n;                 for (i=0; i<n; i++)                 {                                 cout << "Masukan nilai ke "<< i+1 << " : ";                                 cin>> A[i];                 }                 int totg=0, gnp=0, totj=0, gjl=0;                 for (i=0; i<n; i++)                 {                                 if (A[i]%2==0)                                 {                                                 totg=totg+A[i];                                                 gnp=gnp+1;                                 }                                 else                                 {                                                 totj=totj+A[i];                                                 gjl=gjl+1;                                 }                              }                 cout << "Jumlah Bilangan Genap : " << gnp << endl;                 cout << "Jumlah Genap : " << totg << endl;                 cout << "Jumlah Bilangan ganjil : " << gjl << endl;                 cout << "Jumlah Ganjil : " << totj;                                 return 0; }

5.     Menghitung Nilai Max dan Min

Menghitung Nilai Max dan Min #include <iostream> using namespace std; int main () {                 float A[100];                 int n, i,j, max = A[0];// min = A[0];                 cout << "masukan nilai N : ";                 cin>>n;                 for (i=0; i<n; i++)                 {                                 cout << "Masukan nilai ke "<< i+1 <<" : ";                                 cin >>A[i];                 }                 for (i=0; i<n; i++)                 {                                 if ( A[i] > max )                                                 max = A[i];                 }                 int min = A[0];                 for (j=0; j<n; j++)                 {                                 if ( A[j] < min )                                                 min = A[j];                                                 //cout << min << endl;                 }                 cout << "nilai Max : " << max << endl;                 cout << "nilai Min : " << min; return 0; }

while

max=A[0]

i=0

while (i<n) do

read(A[i])

i=i+1

endwhile

i=1

while (i<=n) do

if( A[i] > max

  

6.     Melakukan pencarian hitungan di array

#include <iostream> using namespace std; int main () {                 int n, i, j, tot=0, A[100];                 cout << "Masukan Bilangan : ";                 cin>>n;                 for (i=0; i<n; i++)                 {                                 cout << "Masukan nilai ke "<< i+1 <<" : ";                                 cin>>A[i];                 }                 cout << "Masukan Angka yang akan di hitung frekuensinya : ";                 cin>> A[i];                 for (j=0; j<n; j++)                 {                                 if (A[j]==A[i])                                 {                                                 cout<<"Nilai yang di cari terdapat di index ke : "<<j+1 ;                                                 break;                                 }                 }                                 return 0; }
