Golang : Print instead of building pyramids



Tags : golang pyramids for-loop

Building a pyramid using ancient Egyptians way can be too difficult for more software developers. Just for fun, let's print some pyramids on the terminal instead of building them stones by stones.

Here you go!


 package main

 import (
  "fmt"
 )

 func main() {

  var rows = 5

  fmt.Println("Half pyramid")
  for i := 0; i < rows; i++ {

 for j := 0; j <= i; j++ {
 fmt.Print("∎")
 }

 fmt.Print("\n")
  }

  fmt.Println("Full pyramid")
  for i := 0; i < rows; i++ {

 for j := 0; j <= rows-i; j++ {
 fmt.Print(" ")
 }

 for k := 0; k <= i; k++ {
 fmt.Print("∎ ")
 }

 fmt.Print("\n")
  }

  fmt.Println("Inverted full pyramid")
  for i := rows; i > -1; i-- {

 for j := 0; j <= rows-i; j++ {
 fmt.Print(" ")
 }

 for k := 0; k <= i; k++ {
 fmt.Print("∎ ")
 }

 fmt.Print("\n")
  }

 }

Output:

 Half pyramid
 ∎
 ∎∎
 ∎∎∎
 ∎∎∎∎
 ∎∎∎∎∎
 Full pyramid
 ∎
 ∎ ∎
 ∎ ∎ ∎
 ∎ ∎ ∎ ∎
 ∎ ∎ ∎ ∎ ∎
 Inverted full pyramid
  ∎ ∎ ∎ ∎ ∎ ∎
 ∎ ∎ ∎ ∎ ∎
 ∎ ∎ ∎ ∎
 ∎ ∎ ∎
 ∎ ∎
 ∎
