program sederhana

1. Menghitung nilai rata-rata sederhana

Dev C++

source code :

#include <iostream>
#include <conio.h>

using namespace std;

int main() {
   
    float angka, total = 0, rata;
    int jumlah;
   
    cout << "1. Mencari Rata-rata. (jumlah angka ditentukan)" << endl;
    cout << endl;
    cout << "masukkan jumlah angka      : "; cin >> jumlah;
    cout << endl;
   
    for (int i = 1; i <= jumlah; i++) {
        cout << "Masukkan angka            : "; cin >> angka;
        total = total + angka;
    }
   
    cout << endl;
    cout << "Total                      : " << total << endl;
    rata = total / jumlah;
    cout << "Rata-rata                 : " << rata;
    return 0;
}

outputnya :

2. Mencari nilai max, min dan rata

Dev C++

source code :

#include <cstdlib>
#include <iostream>
 
using namespace std;
 
int main(int argc, char *argv[])
{
    int x[100],n,max,min,i;
    double a,b;
    cout<<"Masukkan Banyaknya Data : ";cin>>n;
    for (i=0;i<n;i++)
    {
     cout<<"Masukan Nilai " <<i+1<<" : ";cin>>x[i];
    }
    max = x[0];
    min = x[0];
    for (i=0;i<n;i++)
    {
     if (max < x[i])
     {
       max = x[i];
      }
     if (min > x[i])
     {
       min = x[i];
      }
    }
    cout<<"Nilai tertinggi = "<<max<<endl;
    cout<<"Nilai terendah = "<<min<<endl;
    a=0;
    for (int i=0;i<n;i++)
    {
     a=a+x[i];
    }
    b=a/n;
    cout<<"Rata-Rata : "<<a<<"/"<<n<<" = "<<b<<endl;
    system("PAUSE");
    return EXIT_SUCCESS;  

}

outputnya :

3. Mencari nilai pangkat

Dev C++

source code :

#include <iostream>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */
using namespace std;

int kali(int i, int n, int p){
if(i<=n)
return p*kali(i+p,n,p);
}
int main(int argc, char** argv) {
int x,y,i=0;

cout<<"menghitung hasil perpangkatan\n";
cout<<"nilai pertama:";cin>>x;
cout<<"masukan hasil pangkat:";cin>>y;
cout<<"hasil="<<kali(i,y,x);
return 0;
}

outputnya :
