【go语言计算年龄生肖星座】go语言根据出生日期 计算年龄，所属星座，生肖

一、需求分析
go语言根据出生日期 计算年龄，所属星座，生肖

二、运行效果

"D:\Program Files (x86)\JetBrains\Gogland 171.3780.106\bin\runnerw.exe" D:/Go\bin\go.exe run D:/Go/code/src/awesomeProject/age_calculate.go24 狮子座 鸡Process finished with exit code 0

三、实现源代码

package mainimport ("fmt""time")func GetTimeFromStrDate(date string) (year, month, day int) {    const shortForm = "2006-01-02"    d, err := time.Parse(shortForm, date)    if err != nil {        fmt.Println("出生日期解析错误！")        return 0,0,0    }    year = d.Year()    month = int(d.Month())    day = d.Day()    return}func GetZodiac(year int) (zodiac string) {    if year <= 0 {        zodiac = "-1"    }    start := 1901    x := (start - year) % 12    if x == 1 || x == -11 {        zodiac = "鼠"    }    if x == 0 {        zodiac = "牛"    }    if x == 11 || x == -1 {        zodiac = "虎"    }    if x == 10 || x == -2 {        zodiac = "兔"    }    if x == 9 || x == -3 {        zodiac = "龙"    }    if x == 8 || x == -4 {        zodiac = "蛇"    }    if x == 7 || x == -5 {        zodiac = "马"    }    if x == 6 || x == -6 {        zodiac = "羊"    }    if x == 5 || x == -7 {        zodiac = "猴"    }    if x == 4 || x == -8 {        zodiac = "鸡"    }    if x == 3 || x == -9 {        zodiac = "狗"    }    if x == 2 || x == -10 {        zodiac = "猪"    }    return}func GetAge(year int) (age int) {    if year <= 0 {        age = -1    }    nowyear := time.Now().Year()    age = nowyear - year    return}func GetConstellation(month, day int) (star string) {    if month <= 0 || month >= 13 {        star = "-1"    }    if day <= 0 || day >= 32 {        star = "-1"    }    if (month == 1 && day >= 20) || (month == 2 && day <= 18) {        star = "水瓶座"    }    if (month == 2 && day >= 19) || (month == 3 && day <= 20) {        star = "双鱼座"    }    if (month == 3 && day >= 21) || (month == 4 && day <= 19) {        star = "白羊座"    }    if (month == 4 && day >= 20) || (month == 5 && day <= 20) {        star = "金牛座"    }    if (month == 5 && day >= 21) || (month == 6 && day <= 21) {        star = "双子座"    }    if (month == 6 && day >= 22) || (month == 7 && day <= 22) {        star = "巨蟹座"    }    if (month == 7 && day >= 23) || (month == 8 && day <= 22) {        star = "狮子座"    }    if (month == 8 && day >= 23) || (month == 9 && day <= 22) {        star = "处女座"    }    if (month == 9 && day >= 23) || (month == 10 && day <= 22) {        star = "天秤座"    }    if (month == 10 && day >= 23) || (month == 11 && day <= 21) {        star = "天蝎座"    }    if (month == 11 && day >= 22) || (month == 12 && day <= 21) {        star = "射手座"    }    if (month == 12 && day >= 22) || (month == 1 && day <= 19) {        star = "魔蝎座"    }    return star}func main() {    y, m, d := GetTimeFromStrDate("1993-08-20")    fmt.Println(GetAge(y),GetConstellation(m, d),GetZodiac(y))}
