# Golang Example to check Largest, Smallest of three numbers This post covers two programs, the First program is to check the largest of three numbers, the second program is to check the smallest of three numbers.

To understand these programs, You should have understood the following features

## Example Program to check largest/biggest of three numbers using if-else statement

In the below program, Read the three input numbers from the user using the `Scanln` function and store in number1,numer2,number3 variables

To check the largest of three numbers,

Following conditions are checked using the if-else statement.

• if number1 is greater than or equal to number2 and number3, number1 is the largest number
• if number2 is greater than or equal to number1 and number3, number2 is the largest number
• else number 3 is the largest
``````package main

import (
"fmt"
)

func main() {
var number1, number2, number3 int
fmt.Print("Enter First Number:")
fmt.Scanln( & number1)
fmt.Print("Enter Second Number:")
fmt.Scanln( & number2)
fmt.Print("Enter Third Number:")
fmt.Scanln( & number3)

fmt.Printf("The Entered three numbers are %d %d %d \n", number1, number2, number3)

if number1 >= number2 && number1 >= number3 {
fmt.Println("Largest of three numbers: ", number1)
} else if number2 >= number1 && number2 >= number3 {
fmt.Println("Largest of three numbers: ", number2)
} else {
fmt.Println("Largest of three numbers: ", number3)
}
}

``````

The output of the above code is

``````Enter First Number:25
Enter Second Number:96
Enter Third Number:745
The Entered three numbers are 25 96 745
Largest of three numbers:  745

``````

## Example program to find smallest/lesser of three numbers

The following program takes three numbers from user input and stores it in number1,number2,number3

To check the smallest of three numbers, the Following conditions are checked using if-else statement

• if number1 is lesser than or equal to number2 and number3, number1 is the smallest number
• if number2 is lesser than or equal to number1 and number3, number2 is the smallest number
• else number 3 is the smallest
``````package main

import (
"fmt"
)

func main() {
var number1, number2, number3 int
fmt.Print("Enter First Number:")
fmt.Scanln( & number1)
fmt.Print("Enter Second Number:")
fmt.Scanln( & number2)
fmt.Print("Enter Third Number:")
fmt.Scanln( & number3)

fmt.Printf("The Entered three numbers are %d %d %d \n", number1, number2, number3)

if number1 <= number2 && number1 <= number3 {
fmt.Println("Smallest of three numbers: ", number1)
} else if number2 <= number1 && number2 <= number3 {
fmt.Println("Smallest of three numbers: ", number2)
} else {
fmt.Println("Smallest of three numbers: ", number3)
}
}
``````

Output is 4

``````Enter First Number:5
Enter Second Number:78
Enter the Third Number:1
The Entered three numbers are 5 78 1
Smallest of three numbers:  1
``````
