# Go Program to Print Pascal Triangle

Write a Go program to print the pascal triangle number pattern using for loop.

```package main

import (
"fmt"
"strconv"
)

func main() {

var i, j, row, number int

fmt.Print("Enter Pascals Number Triangle Pattern Rows = ")
fmt.Scanln(&row)

fmt.Println("**** Pascals Number Triangle Pattern ****")

for i = 0; i < row; i++ {
number = 1
fmt.Printf("%"+strconv.Itoa((row-i)*2)+"s", "")
for j = 0; j <= i; j++ {
fmt.Printf("%4d", number)
number = number * (i - j) / (j + 1)
}
fmt.Println()
}
}```

It is another way of writing a golang program to print the pascals triangle of numbers.

```package main

import "fmt"

func factorialCal(num int) int {
if num == 0 || num == 1 {
return 1
}
return num * factorialCal(num-1)
}
func main() {

var i, j, num int

fmt.Print("Rows to Print the Pascal Triangle = ")
fmt.Scanln(&num)

fmt.Println("\nPascal Triangle")
for i = 0; i < num; i++ {
for j = 1; j <= num-i-2; j++ {
fmt.Print(" ")
}
for j = 0; j <= i; j++ {
fmt.Printf("%d ", factorialCal(i)/(factorialCal(j)*factorialCal(i-j)))
}
fmt.Println()
}
}```
``````Rows to Print the Pascal Triangle = 8
