Program to sort an array of integers in ascending order using quick sort.

#include<iostream>
#include<conio.h>
using namespace std;
int a[10],l,u,i,j;
void quick(int *,int,int);
int main()
{
cout<<"Enter 10 Elements\n";
for(i=0;i<10;i++)
cin>>a[i];
l=0;
u=9;
quick(a,l,u);
cout <<"\nSorted Elements\n";
for(i=0;i<10;i++)
cout<<a[i]<< " ";
cout<<"\n/*\nName-Sanjampreet Singh\nRoll Number-1507967\n*/";
return 0;
}

void quick(int a[],int l,int u)
{
   int p,temp;
if(l<u)
{
p=a[l];
i=l;
j=u;
while(i<j)
{
   while(a[i]<=p&&i<j)
i++;
   while(a[j]>p&&i<=j)
   j--;
if(i<=j)
   {
temp=a[i];
a[i]=a[j];
a[j]=temp;
}
}
temp=a[j];
a[j]=a[l];
a[l]=temp;
cout <<"\n";
for(i=0;i<10;i++)
cout <<a[i]<<" ";
quick(a,l,j-1);
quick(a,j+1,u);
}
}
