Tentukan modus dari n buah data berupa bilangan bulat, di mana besar datanya antara 1 sampai dengan 10.input c++:
#include <iostream>
#include <math.h>
using namespace std;
class HitungStatistik {
friend ostream& operator<<(ostream&, HitungStatistik&);
friend istream& operator>>(istream&, HitungStatistik&);
public:
HitungStatistik();
void hitung_modus();
private:
void maksimum();
void frekuensi();
int maks, item;
int n;
int A[20];
int f[11];
};
HitungStatistik::HitungStatistik()
{ for (int i=0; i<20; i++) f[i] = 0; }
istream& operator>>(istream& in, HitungStatistik& a) {
cout << "Banyaknya data : ";
cin >> a.n;
for (int i = 0; i < a.n; i++) {
cout << "Data ke- : " << i+1 << " > ";
cin >> a.A[i];
}
return in;
}
void HitungStatistik::maksimum()
{
maks = f[0];
item = 1;
for (int i=0; i<n; i++)
if (f[i] > maks) {
maks = f[i];
item = i;
}
cout << "Modus = " << item;
}
void HitungStatistik::frekuensi()
{
for (int i=1; i<n; i++) ++f[A[i]];
}
void HitungStatistik::hitung_modus() {
cout << "Frekuensi running\n";
frekuensi();
maksimum();
}
ostream& operator<<(ostream& out, HitungStatistik& a) {
cout << "Mulai ...\n";
a.hitung_modus();
cout << "Nilai modus : " << a.item;
return out;
}
main() {
HitungStatistik run;
cin >> run;
cout << run;
return 0;
}

output c++:
