Codding dari gabungan Beberapa sorting

Setelah selesai kuliah di semester tiga ini, dan di semester 3di palajarin tentag sorting trus ,belajar beberapa tentag sorting,  maka ahirnya saya punya sedikit percikan fikiran yang bisa di share ke kalian semua...
ni gan contoh coddingya:

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

int data[100],data2[100];
int n;

void tukar(int a,int b)
{
int t;
t = data[b];
data[b] = data[a];
data[a] = t;
}

void bubble_sort()
{
for(int i=1;i<n;i++)
{
for(int j=n-1;j>=i;j--)
{
if(data[j]<data[j-1]) tukar(j,j-1);
}
}
cout<<"bubble sort selesai"<<endl;
}

void exchange_sort()
{
for (int i=0; i<n-1; i++)
{
for(int j = (i+1); j<n; j++)
{
if (data [i] > data[j]) tukar(i,j);
}
}
cout<<"exchange sort selesai!"<<endl;
}

void selection_sort()
{
int pos,i,j;
for(i=0;i<n-1;i++)
{
pos = i;
for(j = i+1;j<n;j++)
{
if(data[j] < data[pos]) pos = j;
}
if(pos != i) tukar(pos,i);
}
cout<<"selection sort selesai!"<<endl;
}

void insertion_sort()
{
int temp,i,j;
for(i=1;i<n;i++)
{
temp = data[i];
j = i -1;
while(data[j]>temp && j>=0)
{
data[j+1] = data[j];
j--;
}
data[j+1] = temp;
}
cout<<"insertion sort selesai!"<<endl;
}

void QuickSort(int L, int R)
{
int i, j;
int mid;

i = L;
j = R;
mid = data[(L+R) / 2];

do
{
while (data[i] < mid) i++;
while (data[j] > mid) j--;

if (i <= j)
{
tukar(i,j);
i++;
j--;
};
} while (i < j);

if (L < j) QuickSort(L, j);
if (i < R) QuickSort(i, R);
}


void Input()
{
cout<<"Masukkan jumlah data = "; cin>>n;
for(int i=0;i<n;i++)
{
cout<<"Masukkan data ke-"<<(i+1)<<" = "; cin>>data[i];
data2[i] = data[i];
}
}

void Tampil()
{
cout<<"Data : "<<endl;
for(int i=0;i<n;i++)
{
cout<<data[i]<<" ";
}
cout<<endl;
}

void AcakLagi()
{
for(int i=0;i<n;i++)
{
data[i] = data2[i];
}
cout<<"Data sudah teracak"<<endl;
}

void main()
{
int pil;
clrscr();
do
{
clrscr();
cout<<"Program Sorting"<<endl;
cout<<"*********************************************"<<endl;
cout<<" 1. Masukan Data"<<endl;
cout<<" 2. Bubble Sort"<<endl;
cout<<" 3. Exchange Sort"<<endl;
cout<<" 4. Selection Sort"<<endl;
cout<<" 5. Insertion Sort"<<endl;
cout<<" 6. Quick Sort"<<endl;
cout<<" 7. Tampilkan Data"<<endl;
cout<<" 8. Acak Data"<<endl;
cout<<" 9. Exit"<<endl;
cout<<" Pilihan Anda = "; cin>>pil;
switch(pil)
{
case 1:Input(); break;
case 2:bubble_sort(); break;
case 3:exchange_sort(); break;
case 4:selection_sort(); break;
case 5:insertion_sort(); break;
case 6:QuickSort(0,n-1);
cout<<"quick sort selesai!"<<endl;
break;
case 7:Tampil(); break;
case 8:AcakLagi(); break;
}
getch();
}while(pil!=9);
}



Semoga Bermanfaat ya gan....!
