Golang程序打印X星图案

在本教程中，我们将学习如何使用Go编程语言来打印X星形图案。

语法

for initialization; condition; update {
   statement(s)
}

例子。使用单个函数打印x星形图案的Go程序代码

算法

第1步 – 导入软件包fmt和strconv软件包。
第2步 – 启动函数 main()。
第3步 – 声明并初始化变量。
第4步 – 使用带有条件和增量器的for循环。
第5步 – 使用 fmt.Println() 打印结果。

例子

// GOLANG PROGRAM TO PRINT X STAR PATTERN
package main

// fmt package provides the function to print anything
import "fmt"

// start the function main()
func main() {
   fmt.Println("Golang Program to print X star pattern")

   // Declare the integer variables
   var i, a, number, row int

   // initialize the row variable
   row = 8

   // print the X star pattern
   fmt.Println("X Star Pattern")

   // Run an outer loop to iterate through rows with
   // structure for (i=1; i<= number; i++) (where number = row* 2 - 1)
   number = row*2 - 1

   // Use of For Loop
   // This loop starts when i = 1
   // executes till i<=number condition is true
   // post statement is i++
   for i = 1; i <= number; i++ {
      // Since each row contains exactly row * 2 - 1 columns.
      // Therefore, run inner loop as for (a=1; a<=number; a++)
      for a = 1; a <= number; a++ {
         // For the first diagonal i.e. when row and column number both
         // are equal, print star whenever if(i == a).
         // For the second diagonal i.e. stars are printed if(a == number - i + 1)
         if a == i || a == number-i+1 {
            fmt.Printf("*")
         }
         fmt.Printf(" ")
      }
      // PRINT THE RESULT
      fmt.Println()
   }
}
