Go Program to Print Exponentially Increased Star Pattern

Write a Go Program to Print Exponentially Increased Star Pattern. In this Golang Exponentially Increased Star Pattern example, the first for loop iterates from start to end. The second for loop (for j = 1; j <= math.Pow(2, i); j++) iterates from 1 to 2 power i value. Within the loop, we are printing the star.

package main

import (
    "fmt"
    "math"
)

func main() {

    var i, j, rows float64

    fmt.Print("Enter Total Rows = ")
    fmt.Scanln(&rows)

    fmt.Println("Exponentially Increasing Star Pattern")
    for i = 0; i <= rows; i++ {
        for j = 1; j <= math.Pow(2, i); j++ {
            fmt.Print("* ")
        }
        fmt.Println()
    }
}

This Golang program allows entering any symbol and prints the exponentially increased pattern of that symbol. For more star pattern examples, please refer to the Go Star Pattern programs article.

package main

import (
    "fmt"
    "math"
)

func main() {

    var i, j, rows float64
    var ch string

    fmt.Print("Enter Total Rows = ")
    fmt.Scanln(&rows)

    fmt.Print("Enter The Symbol = ")
    fmt.Scanln(&ch)

    fmt.Println("Exponentially Increasing Star Pattern")
    for i = 0; i <= rows; i++ {
        for j = 1; j <= math.Pow(2, i); j++ {
            fmt.Printf("%s ", ch)
        }
        fmt.Println()
    }
}
