Go Program to Check Leap year

A leap year contains 366 days, and any year divisible by four except the century years are called leap years. Furthermore, if the century year divisible by 400, then it is a leap year. In this Go program, we use the If else statement (if yr%400 == 0 || (yr%4 == 0 && yr%100 != 0)) and logical operators to check leap year or not.

package main

import "fmt"

func main() {

    var yr int

    fmt.Print("\nEnter the Year to Check for Leap = ")
    fmt.Scanln(&yr)

    if yr%400 == 0 || (yr%4 == 0 && yr%100 != 0) {
        fmt.Println(yr, " is a Leap Year")
    } else {
        fmt.Println(yr, " is Not a Leap Year")
    }
}

Golang Program to Check Leap year using Else If

    var yr int

    fmt.Print("\nEnter the Year to Check for Leap = ")
    fmt.Scanln(&yr)

    if yr%400 == 0 {
        fmt.Println(yr, " is a Leap Year")
    } else if yr%100 == 0 {
        fmt.Println(yr, " is Not a Leap Year")
    } else if yr%4 == 0 {
        fmt.Println(yr, " is a Leap Year")
    } else {
        fmt.Println(yr, " is Not a Leap Year")
    }
}

SureshMac:Goexamples suresh$ go run leap2.go

Enter the Year to Check for Leap = 1990
1990  is Not a Leap Year
SureshMac:Goexamples suresh$ go run leap2.go

Enter the Year to Check for Leap = 2020
2020  is a Leap Year

In this Go program, we used the Nested if statement to find whether the user-entered year is a leap year or not.

package main

import "fmt"

func main() {

    var yr int

    fmt.Print("\nEnter the Year to Check for Leap = ")
    fmt.Scanln(&yr)

    if yr%4 == 0 {
        if yr%100 == 0 {
            if yr%400 == 0 {
                fmt.Println(yr, " is a Leap Year")
            } else {
                fmt.Println(yr, " is Not a Leap Year")
            }
        } else {
            fmt.Println(yr, " is a Leap Year")
        }
    } else {
        fmt.Println(yr, " is Not a Leap Year")
    }
}

SureshMac:Goexamples suresh$ go run leap3.go

Enter the Year to Check for Leap = 1200
1200  is a Leap Year
SureshMac:Goexamples suresh$ go run leap3.go

Enter the Year to Check for Leap = 2015
2015  is Not a Leap Year
