# Program to print the pattern ‘G’

• Difficulty Level : Hard
• Last Updated : 07 Apr, 2021

In this article, we will learn how to print the pattern G using stars and white-spaces. Given a number n, we will write a program to print the pattern G over n lines or rows.
Examples:

```Input : 7
Output :
***

Input : 9
Output :
*****

In this program, we have used the simple logic of iteration over lines to create the pattern G. Please look at the image below which represents the pattern G in the form of a 2-d matrix, where mat[i][j] = ‘ij’: If we try to analyze this picture with a (row, column) matrix and the circles represent the position of stars in the pattern G, we will learn the steps. Here we are performing the operations column-wise. So for the first line of stars, we set the first if condition, where the row position with 0 and (n-1) won’t get the stars and all other rows from 1 to (n-1), will get the stars. Similarly, for the second, third and fourth column we want stars at the position row = 0 and row = (n-1). The other steps are self-explanatory and can be understood from the position of rows and columns in the diagram.
Below is the implementation of above idea:

## C++

 `// C++ program to print the pattern G``#include ``using` `namespace` `std;` `void` `pattern(``int` `line)``{``    ``int` `i, j;``    ``for``(i = 0; i < line; i++)``    ``{``        ``for``(j = 0; j < line; j++)``        ``{``            ``if``((j == 1 && i != 0 && i != line - 1) ||``              ``((i == 0 || i == line - 1) && j > 1 &&``              ``j < line - 2) || (i == ((line - 1) / 2) &&``              ``j > 2 && j < line - 1) || (j == line - 2 &&``              ``i != 0 && i >= ((line - 1) / 2) && i != line - 1))``                ``printf``(``"*"``);``            ``else``                ``printf``( ``" "``);` `        ``}``        ``printf``(``"\n"``);``    ``}``}` `// Driver code``int` `main()``{``    ``int` `line = 7;``    ``pattern(line);``    ``return` `0;``}` `// This code is contributed``// by  vt_m.`
