arrays - c (and objc, and c++ and objc++) - char* argv[] -

-

I am cloning the echo command and it is more complicated than what I was thinking. Here's my problem: A four * argv [] How does it work? I know how my string [] works, but there is no strange way to create a string:

  • Is it an indicator of array of characters or array of characters? Why I * argv [n], it shows me n logic, not four char ... can cheers

    behaves four argv [] such as char ** argv will behave you a Char argv [] [] can also be used in the same way.

    By default, when you call * argv , you should enter Argv [0] and * argv [n] gives argv [0] [n]

    edit: change argv [x] a std :: String in: 

      std :: string s (argv [x]);   
     s is a standard string at that point. But keep in mind that you should have a zero ended string, it's  four ** !     will not work for random binary data,

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
