Golang Program To Print Mirror Lower Star Triangle Pattern

In this tutorial, we will learn how to print the mirror lower star triangle pattern using G programming language.

Syntax

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

In the code, we use the for loop to repeat a block of code until the specified condition is met.

Example: Golang Program to Print Mirror Lower Star Triangle pattern using One Single Function

Algorithm

• Step 1 ? Import the package fmt.

• Step 2 ? Start the 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 MIRROR LOWER STAR TRIANGLE PATTERN package main // fmt package provides the function to print anything import "fmt" func main() { fmt.Println("GOLANG PROGRAM TO PRINT MIRROR LOWER STAR TRIANGLE PATTERN") // declare the variables var i int var j int var row int // initialize the variables row = 8 //Outer loop 1 // prints the first half triangle GOLANG PROGRAM TO PRINT MIRROR LOWER STAR TRIANGLE PATTERN for i = 0; i <= row; i++ { //inner loop 1 for j = 1; j < i; j++ { //prints space between two stars fmt.Print(" ") } // Inner loop 2 for j = i; j <= row; j++ { // Print star fmt.Print("*" + " ") } // Ending line after each row fmt.Println() } // Outer loop 2 // prints the second half triangle for i = row - 1; i >= 0; i-- { // Inner loop 1 for j = 0; j < i; j++ { // Print whitespace fmt.Print(" ") } // Inner loop 2 for j = i; j <= row-1; j++ { // Print star fmt.Print("*" + " ") } // Ending line after each row fmt.Println() } } 
 
 
 

Output

GOLANG PROGRAM TO PRINT MIRROR LOWER STAR TRIANGLE PATTERN * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 

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 three integer variables i, j and row. Initialize the row variable to an integer value you want for the number of rows of the lower mirror star triangle 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 using fmt.Println().

Conclusion

We have successfully compiled and executed the Golang program code to print the mirror lower star triangle pattern in the above example.
