Random array sorting..

[ipippkimo]

Hi,
I would like to make a random array in 4*5 first.
Then supply selection and bubble sort to fix the
same number in two separate lines. (show the
numbers in one line first.)

Thank for help

#include<iostream>
#include<iomanip>
#include<ctime>
#include <cstdlib>
using namespace std;
int main()
{
	int x = 4, y = 5,a;
    int **ptr = new int *[x];
	int i,j,n,temp1,temp2;
    for(int i = 0; i<y; i++)
    {
        ptr[i] = new int[y];
    }

    for(int j = 0; j<x; j++)
    {
        for(int k = 0; k<y; k++)
        {
			a =( rand() % 100 )+ 1;
            ptr[j][k] = a;
            cout<<ptr[j][k]<<" ";
        }
            for(int k = 1; k<j; k++)
			{
			a = rand() % 100 + 1;
            ptr[j][k] = a;
            cout<<ptr[j][k];
         	}
		  cout <<endl;
    }
}
	int ptr[20],j,a;	
 	 for(int j = 0; j< 19; j++)  
	{ 
	a =  rand() % 100 + 1;
    ptr[20]=a;  
    cout<<ptr[20]<<" ";   
    } 
	cout<<"\nArray after selection sort: "<<temp1;  
    cout<<"\nArray after bubble sort: "<<temp2;
{
	for (j=0;j<n;j++);	//selection sort
     for(j=i+1;j<n;j++)
	  if(ptr[j]<ptr[i])
	     i=j;
	  if (i!=i)
		{
		temp1=ptr[j];
        ptr[j]=ptr[j+1];
        ptr[j+1]=temp1;
        }	
}
	{
		 for (i = 0; i < n ; i++);  //bubble sort	
		     for(j=0;j<(n-i);++j)
				if(ptr[j]>ptr[j+1])
				{
			    temp2=ptr[j];
                ptr[j]=ptr[j+1];
                ptr[j+1]=temp2;
                }
    }
