C++ program of bubble sorting array

In this program we will learn how  to sort elements of array in bubble sorting order.
The code is given below.

//Code starts
#include<iostream>
#include<conio.h>

using namespace std;

int main()
{
int a[50],n,i,j,temp;
cout<<"Enter the size of array: ";
cin>>n;

for(i=0;i<n;++i)
{
cout<<"Enter number at index ["<<i<<"] : ";
cin>>a[i];
}

for(i=1;i<n;++i)
{
for(j=0;j<(n-i);++j)
{
if(a[j]>a[j+1])
{
temp=a[j];
a[j]=a[j+1];
a[j+1]=temp;
}
}
}

cout<<"Array after bubble sort:";
for(i=0;i<n;++i)
cout<<" "<<a[i];

getch();
}
//Code ends
