# Program to print Even Odd Number Pyramid

Given the total number of rows as n, the task is to print the given pattern.

*
1*
*2*
1*3*
*2*4*
1*3*5*
*2*4*6*
1*3*5*7*
*2*4*6*8*
1*3*5*7*9*
.
.

Examples:

```Input: n = 5
Output:
*
1*
*2*
1*3*
*2*4*

Input: n = 10
Output:
*
1*
*2*
1*3*
*2*4*
1*3*5*
*2*4*6*
1*3*5*7*
*2*4*6*8*
1*3*5*7*9*
```

Below is the solution to the above problem:

## C++

 `// CPP program to print Even Odd Number Pyramid ` ` `  `#include ` `using` `namespace` `std; ` ` `  `// function for creating pattern ` `void` `Pattern(``int` `n) ` `{ ` `    ``// Initialization ` `    ``int` `i, j, k; ` `    ``for` `(i = 1; i <= n; i++) { ` ` `  `        ``for` `(j = 1, k = i; j <= i; j++, k--) { ` ` `  `            ``if` `(k % 2 == 0) { ` ` `  `                ``// displaying the numbers ` `                ``cout << j; ` `            ``} ` `            ``else` `{ ` ` `  `                ``// displaying the stars ` `                ``cout << ``"*"``; ` `            ``} ` `        ``} ` `        ``cout << ``"\n"``; ` `    ``} ` `} ` ` `  `// driver code ` `int` `main() ` `{ ` ` `  `    ``// Get n ` `    ``int` `n = 5; ` ` `  `    ``// Print the pattern ` `    ``Pattern(n); ` ` `  `    ``return` `0; ` `} `

## C

 `// C program to print Even Odd Number Pyramid ` ` `  `#include ` ` `  `// function for creating pattern ` `void` `Pattern(``int` `n) ` `{ ` `    ``// Initialization ` `    ``int` `i, j, k; ` `    ``for` `(i = 1; i <= n; i++) { ` `        ``for` `(j = 1, k = i; j <= i; j++, k--) { ` `            ``if` `(k % 2 == 0) { ` ` `  `                ``// displaying the numbers ` `                ``printf``(``"%d"``, j); ` `            ``} ` `            ``else` `{ ` ` `  `                ``// displaying the stars ` `                ``printf``(``"*"``); ` `            ``} ` `        ``} ` `        ``printf``(``"\n"``); ` `    ``} ` `} ` ` `  `// driver code ` `int` `main() ` `{ ` ` `  `    ``// Get n ` `    ``int` `n = 5; ` ` `  `    ``// Print the pattern ` `    ``Pattern(n); ` ` `  `    ``return` `0; ` `} `

## Java

 `// Java program to print above pattern ` ` `  `import` `java.util.Scanner; ` ` `  `class` `Pattern { ` `    ``static` `void` `display(``int` `n) ` `    ``{ ` ` `  `        ``int` `i, j, k; ` `        ``for` `(i = ``1``; i <= n; i++) { ` ` `  `            ``for` `(j = ``1``, k = i; j <= i; j++, k--) { ` ` `  `                ``if` `(k % ``2` `== ``0``) { ` `                    ``// displaying the numbers ` `                    ``System.out.print(j); ` `                ``} ` `                ``else` `{ ` `                    ``// displaying the stars ` `                    ``System.out.print(``"*"``); ` `                ``} ` `            ``} ` `            ``System.out.print(``"\n"``); ` `        ``} ` `    ``} ` `    ``// Driver Code ` `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` ` `  `        ``// Get n ` `        ``int` `n = ``5``; ` ` `  `        ``// Print the pattern ` `        ``display(n); ` `    ``} ` `} `

## Python3

 `# Python3 program to print above pattern  ` `def` `display(n): ` `    ``for` `i ``in` `range``(``1``, n ``+` `1``): ` `        ``k ``=` `i ` `        ``for` `j ``in` `range``(``1``, i ``+` `1``): ` `            ``if` `k ``%` `2` `=``=` `0``: ` `                 `  `                ``# Displaying the numbers  ` `                ``print``(j, end ``=` `'') ` `            ``else``: ` `                 `  `                ``# Displaying the stars  ` `                ``print``(``'*'``, end ``=` `'') ` `            ``k ``-``=` `1` `        ``print``() ` ` `  `# Driver Code  ` ` `  `# Get n  ` `n ``=` `5` ` `  `# Print the pattern  ` `display(n) ` ` `  `# This code is contributed by SamyuktaSHegde  `

## C#

 `// C# program to print above pattern ` `using` `System; ` ` `  `class` `GFG ` `{ ` `static` `void` `display(``int` `n) ` `{ ` ` `  `    ``int` `i, j, k; ` `    ``for` `(i = 1; i <= n; i++)  ` `    ``{ ` ` `  `        ``for` `(j = 1, k = i; j <= i; j++, k--)  ` `        ``{ ` ` `  `            ``if` `(k % 2 == 0)  ` `            ``{ ` `                ``// displaying the numbers ` `                ``Console.Write(j); ` `            ``} ` `            ``else`  `            ``{ ` `                ``// displaying the stars ` `                ``Console.Write(``"*"``); ` `            ``} ` `        ``} ` `        ``Console.Write(``"\n"``); ` `    ``} ` `} ` ` `  `// Driver Code ` `public` `static` `void` `Main() ` `{ ` ` `  `    ``// Get n ` `    ``int` `n = 5; ` ` `  `    ``// Print the pattern ` `    ``display(n); ` `} ` `} ` ` `  `// This code is contributed by anuj_67 `
