#include<iostream>
using namespace std;
void sort(int al[30], int l)
{
//we use insertion sort to sort the array.
int p,q,k;
for(q=1;q<l;q++) //starting from the 2nd item of the array.
{
k= al[q]; //taking qth item as key value.
p=q-1;
while(p>=0 && al[p]>k)
{
al[p+1]=al[p]; //all items those are greaer than al[q] are shifted //to right.
p=p-1;
}
al[p+1]=k;
}
}
int main()
{
int p,l, arrl[30];
cout<<"Enter the number of items in your array: ";
cin>>l;
cout<<endl;
cout<<"Enter your "<<l<<" items"<<endl;
for(p=0;p<l;p++)
{
cin>>arrl[p];
}
sort(arrl, l); //call function sort() to sort the array.
cout<<"The array after sorting: ";
for(p=0;p<l;p++)
{
cout<<arrl[p]<<" ";
}
cout<<endl;
cout<<"The smallest item is: ";
cout<<arrl[0]<<endl;
cout<<"The middle item is: ";
cout<<arrl[l/2]<<endl;
cout<<"The biggest item is: ";
cout<<arrl[l-1]<<endl;
}
