Create a Various Pattern using C#

This blog explains you how to draw a different pattern using C#.

These pattern logic will be useful for the interview preparation  

 

1. 4*4 Matrix:

for (int i = 0; i < 4; i++)
{
    for (int j = 0; j < 4; j++)
    {
        Console.Write("*");
    }
    Console.WriteLine();

}

Output:

 

 

2. Right angle triangle:

for (int i = 0; i <= 4; i++)
{
    for (int j = 0; j <= i; j++)
    {
        Console.Write("*");

    }
    Console.WriteLine();
}

Output:

 

 

 

 3. Right angle triangle with numbers: 

for (int i = 1; i <= 4; i++)
{
    for (int j = 1; j <= i; j++)
    {
        Console.Write(j);

    }
    Console.WriteLine();
 }

Output:

 

4. Triangle

for (int i = 1; i <= 4; i++)
{
     for (int j = 0; j <= (4 - i); j++)
     Console.Write(" ");
     for (int k = 1; k <= i; k++)
     Console.Write("*" + " ");

     Console.WriteLine();
}

Output:

 

 

5. Pyramid 

for (int i = 1; i <= 4; i++)
{
    for (int j = 0; j <= (4 - i); j++)
    Console.Write(" ");
    for (int k = 1; k <= i; k++)
    Console.Write("*" + " ");

    Console.WriteLine();
 }
 for (int i = 3; i >= 0; i--)
 {
     for (int j = 0; j < (5 - i); j++)
     Console.Write(" ");
     for (int j = 1; j <= i; j++)
     Console.Write("*" + " ");
     Console.WriteLine();
 }

Output:

 

   

 

 6. Pyramid with numbers.

for (int i = 1; i <= 4; i++)
{
    for (int j = 0; j <= (4 - i); j++)
    Console.Write(" ");
    for (int k = 1; k <= i; k++)
    Console.Write(i + " ");

    Console.WriteLine();
}
for (int i = 3; i >= 0; i--)
{
    for (int j = 0; j < (5 - i); j++)
    Console.Write(" ");
    for (int j = 1; j <= i; j++)
    Console.Write(i + " ");
    Console.WriteLine();
}

Output:
