仓颉变量的使用

let a = 2023
// func b() {}
struct C {}

class D {}

    F | G
}

    let b = 2023
    func fb() {

    }
    fb()
}

    let b = 2024
    public func fb() {
        println(b)
    }
}

struct Copy {
    var data = 2012
}

class Share {
    var data = 2012
}

let element = "仓颉"

main(): Int64 {
    println("hello world")
    //首先，‌在控制台中输入执行chcp 65001命令，‌
    //这个命令的作用是设置控制台的语言编码格式为UTF-8。‌
    //紧接着，‌再次运行仓颉语言的编译运行命令（‌例如cjpm run）‌，‌此时中文显示应该能够恢复正常。‌
    // println("你好，仓颉！")

    println(a)
