Rencana Kuliah Alpro Bulan ke-3

1. Menggeser elemen array

Geser kiri (Algoritma)

Deklarasi:

void tambah (int a,int b,int c)

A[3]=integer

Deskripsi:

Write( "hasil setelah geser ke kiri")

Write(“masukan bil 1 :")

Readß a[1]

Write(“masukan bil 2 : ")

Readßb[2]

Write("masukan bil 3 : ")

Readß c[3]

tambah(a[1],b[2],c[3])

Geser kiri (Raptor)

Geser Kiri (C++)

Geser Kanan (Algoritma)

Deklarasi:

A [5]={20,21,22,23,24} => Integer

n=0,temp=A[4] => Integer

Deskripsi:

Write("Data yang lama\n")

for (n=0;n<5;n++)

Write(" "<<A[n])

Write("Data yang baru : ")

for(int i=5;i>0;i--)

A[i]=A[i-1]

A[0]=temp

for (n=0;n<5;n++)

Write(" "<<A[n])

Geser Kanan (Raptor)

Geser Kanan (C++)

2. Mencari mean, median, modus, max, min dari banyak nilai yang di inputkan

Analisis:
Median :

1 1 2 2 2 3 4 5 5

f[1]=2
f[2]=3
f[3]=1
f[4]=1
f[5]=2

Raptor Mencari Mean :

C++ Mencari Mean,Modus,Median:

#define SIZE 100
#include<iostream>
using namespace std;
float mean_function(float[],int);
float median_function(float[],int);
float mode_function(float[],int);

int main()
{

int i,n,choice;

float array[SIZE],mean,median,mode;
char a;
a='b';
while(a=='b')
{
system ("cls");
cout<<"===========================";
cout<<"\nPROGRAM MEAN, MEDIAN, MODUS\n";
cout<<"===========================\n";
cout<<"Masukan jumlah data = ";
cin>>n;
cout<<"=======================\n";
cout<<"data\n";
cout<<"=======================\n";
for(i=0; i<n; i++)

cin>>array[i];

do
{

cout<<"\n\tEnter pilihan\n\t1.Mean\n\t2.Median\n\t3.Mode\n\t4.Exit\n";
cin>>choice;
switch(choice)
{

case 1:

mean=mean_function(array,n);
cout<<"\nMean ="<<mean;
break;

case 2:

median=median_function(array,n);
cout<<"\n\tMedian = "<<median;
break;

case 3:

mode=mode_function(array,n);
cout<<"\n\tMode = "<<mode;
break;

case 4:

break;

default:

cout<<"salah kode";
break;

}
}while(choice!=4);

}
}

float mean_function(float array[],int n)
{
int i;
float sum=0;
for(i=0;i<n;i++)

sum=sum+array[i];

return (sum/n);

}

float median_function(float a[],int n)
{

float temp;
int i,j;
for(i=0;i<n;i++)

for(j=i+1;j<n;j++)
{

if(a[i]>a[j])
{

temp=a[j];
a[j]=a[i];
a[i]=temp;

}

}

if(n%2==0)
return (a[n/2]+a[n/2-1])/2;
else
return a[n/2];

}

float mode_function(float a[],int n)
{

return (3*median_function(a,n)-2*mean_function(a,n));

}
