is this program correct?

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

using namespace std;
int main()
{
int rows, cols, numOfAster

cout << "Enter the level of of the asterisks:";
cin >> numOfAster;
cout << "Press any key to see the array:\n";
getch();

for (rows=0; rows < numOfAster; rows++)
{
for (cols=(numOfAster=rows); cols > 0; cols--)
cout << "*";
cout << endl;
}

getch();
return 0;
}


>>>and I also need a program that will display a pyramid or Christmas tree.

[screw]

#include<iostream>
#include<conio.h>
using namespace std;

int main()
{
int rows, cols, numOfAster;

cout << "Enter the level of of the asterisks:";
cin >> numOfAster;
cout << "Press any key to see the array:\n";
getch();

for (rows=0; rows < numOfAster; rows++)
{
for (cols=0; cols < rows + 1; cols++) cout << "*";
cout << endl;
}

getch();
return 0;
}

You don't need array here.
