Golang Program To Print X Star Pattern
In this tutorial, we will learn how to print X star pattern using Go programming language.
Syntax
for initialization; condition; update {
statement(s)
}
Example: Go Program Code to Print x Star Pattern Using a Single Function
Algorithm
Step 1 − Import the package fmt and strconv package.
Step 2 − Start function main ().
Step 3 − Declare and initialize the variables.
Step 4 − Use of for loop with condition and incrementor.
Step 5 − Print the result using fmt.Println ().
Example
// 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() } }
Output

Description Of The Code
In the above program, we first declare the package main.
We imported the fmt package that includes the files of package fmt.
Now start the function main().
Declare the four integer variables i, a, number and row. Initialize the row variable to an integer value you want for the number of rows of the star pattern.
Using for loop − The condition is given inside an if statement and stop execution is mentioned once the condition is right.
And last printing the result on the screen using fmt.Println.
Conclusion
We have successfully compiled and executed the Golang program code to print X star pattern in the above two examples.
