Answer 1

public class Pattern
{
public static void Main(string[] args)
{
int i=1,j=1,k=1,bl=0;
do {
//To add required predceding blank space
bl=(9-i)/2;
j=0;
do {
Console.Write(" ");
j++;
} while(j<=bl);
//To add required number of asterisks
k=1;
do {
Console.Write("*");
k++;
} while(k<=i);
//Next line
Console.WriteLine("");
//Incrementing count of asterisks
i=i+2;
} while(i<=9);
//Similar code as above but reverse pattern
i=7;
do {
bl=(9-i)/2;
j=0;
do {
Console.Write(" ");
j++;
} while(j<=bl);
k=1;
do {
Console.Write("*");
k++;
} while(k<=i);
Console.WriteLine("");
//Decrementing count of asterisks
i=i-2;
} while(i>=1);
}
}
