Go Program to Print Right Angled Triangle Number Pattern

Write a Go Program to Print Right angled Triangle Number Pattern. In this Golang Right Angled Triangle Number example, the first for loop iterates from end to start. The second for loop (for j = 1; j <= i; j++) iterates from 1 to i. Within the loop, we print 1’s.

package main

import "fmt"

func main() {

    var i, j, rows int

    fmt.Print("Right Angled Triangle Rows = ")
    fmt.Scanln(&rows)

    fmt.Println("\nRight Angled Triangle Number Pattern")
    for i = 1; i <= rows; i++ {
        for j = 1; j <= i; j++ {
            fmt.Print("1 ")
        }
        fmt.Println()
    }
}

This Golang program allows to input a number and prints the Right angled Triangle pattern of that number. For more number pattern examples, please refer to the Go Number Pattern programs article.

package main

import "fmt"

func main() {

    var i, j, rows, num int

    fmt.Print("Right Angled Triangle Rows = ")
    fmt.Scanln(&rows)

    fmt.Print("Number for Right Angled Triangle = ")
    fmt.Scanln(&num)

    fmt.Println("\nRight Angled Triangle Number Pattern")
    for i = 1; i <= rows; i++ {
        for j = 1; j <= i; j++ {
            fmt.Printf("%d ", num)
        }
        fmt.Println()
    }
}

Right Angled Triangle Rows = 8
Number for Right Angled Triangle = 9

Right Angled Triangle Number Pattern

9 9 
9 9 9 
9 9 9 9 
9 9 9 9 9 
9 9 9 9 9 9 
9 9 9 9 9 9 9 
9 9 9 9 9 9 9 9
