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.

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()
    }
}
