[2014-04-06 14:52:47 - HelloWord] No Launcher activity found!
[2014-04-06 14:52:47 - HelloWord] The launch will only sync the application package on the device!
Ans:

筆試：
1. C語言
題目1: 程式填空

//Descript: str_parser used for parse src string into toke array

//Parameter: src = source string

//                   dst_token = save token string

//                   max_token_count

int str_parser(const char *src, char *dst_token[]; int max_token_count) {

         // You shall use malloc space to save token string

        return 0;

}

 

int main(){

    char *src = "aa bb  ccc";

    char *dst_token[];

    // Call strparser function

    return 0;

}

 

1. 取得使用者輸入的參數
     SET /P VAR1=請輸入Ruby code file path:
2.類似註解

netstat -ano：可以查出現在程式使用中的ip port和使用的程式
Note: 迅雷會佔用80 port
 

C:\Users\Genie>netstat -ano

建立目錄
 

def create_default_dir folder
   if !Dir.exist?(folder)
      puts "%s%s" % ["Folder name = ",folder]
      Dir.mkdir(folder, 0777)

傳進function裡的參數，若不固定數量，則可用*來指定參數
 

def write_log(*elements)
puts elements[0],elements[1],elements[2][0],elements[2][1],elements[3];
end

=begin
ary = Array.new(3)
ary = [1,2,3,4]
write_log(ary)
=end
a="a"
b="b"
c="c"
ary = Array.new(3)
ary = [1,2,3,4]
write_log(a,b,ary,c)
