# Go Program to find First Digit of a Number

Write a Go Program to find the First Digit of a Number using For loop. The for loop condition (for firstDigit >= 10) returns true until the number is greater than or equals to 10. We divide the number by 10 (firstDigit = firstDigit / 10), which will return the first value after all the iterations.

```package main

import "fmt"

func main() {

var firstDigit, number int

fmt.Print("Enter any Number to return First Digit = ")
fmt.Scanln(&number)

firstDigit = number
for firstDigit >= 10 {
firstDigit = firstDigit / 10
}

fmt.Println("The First Digit of this Number    = ", firstDigit)
}```
``````SureshMac:Goexamples suresh\$ go run firstDigit1.go
Enter any Number to return First Digit = 3478
The First Digit of this Number    =  3
SureshMac:Goexamples suresh\$ go run firstDigit1.go
Enter any Number to return First Digit = 9876
The First Digit of this Number    =  9``````

## Go Program to find First Digit of a Number using Functions

In this Golang program, we created a (func findfirstDigit(number int)) function that returns the first digit of a given number. Next, we call this function from main.

```package main

import "fmt"

func findfirstDigit(number int) int {
for number >= 10 {
number = number / 10
}
return number
}
func main() {

var firstDigit, number int

fmt.Print("Enter any Number to return First Digit = ")
fmt.Scanln(&number)

firstDigit = findfirstDigit(number)

fmt.Println("The First Digit of this Number    = ", firstDigit)
}```
