So interpolation works like the following. You first need to have double quotes like using the “”‘s. Then inside of those double quotes you just add the # and then the {} which contains the block of code that you want to run. So in this case you have 2 assignments: name = “James Kirk” … Read more
leaveopinion is not in res/values/strings.xml. So first you need to add it to your strings.xml. Something like this: string name=”leaveopinion”>your_text</string> And to display the real text instead of @string/XXX you need to refresh your_activity.xml . When you did everything above it should be something like this: <?xml version=”1.0″ encoding=”utf-8″?> <resources> <string name=”change”>Change</string> <string name=”Pleasechoosesubject”>Please choose … Read more
preg_match_all(‘/[a-z]+:\/\/\S+/’, $string, $matches); This is an easy way that’d work for a lot of cases, not all. All the matches are put in $matches. Here is a link on using regular expressions in PHP: http://www.regular-expressions.info/php.html. Also, here is a link for email regular expressions: http://www.regular-expressions.info/email.html Good luck. 1 solved Words extraction [closed]
You are on the right track. Use the overload of IndexOf that takes a start index when you look for the second character: int first = picture.IndexOf(‘_’); int second = picture.IndexOf(‘_’, first + 1); string part = picture.Substring(first + 1, second – first – 1); solved Get text between 2 same symbols [closed]
You can do this by using only getline function, but there is a little bit more elegant solution using both genline and operator >>. Note: it is work for c++11. It could be rewritten for earlier c++. Look at here for reference. Only getline using Here is a program which prints a file with words … Read more

Because r is an array of u8, you need to convert it to a valid &str and use push_str method of String. use std::str; fn main() { let rfrce = vec![&[65,66,67], &[68,69,70]]; let mut str = String::new(); for r in rfrce { str.push_str(str::from_utf8(r).unwrap()); } println!(“{}”, str); } Rust Playground 3 solved Proper way to access … Read more
This should work for you: Just PDO::prepare() your INSERT statement and then loop through your explode()‘d input and insert the values into your db. <?php $input = “12345-45678-543245”; $arr = explode(“-“, $input); $host = “localhost”; $dbname = “myDBName”; $user = “root”; $password = “”; try { $dbh = new PDO(“mysql:host=$host;dbname=$dbname”, $user, $password); $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt … Read more

Your string is in fact html – you should use html parser instead. I suggest the excellent lxml.html parser. To answer your question, regexes are greedy by default, that means your .+ part will grab as many chars as it can to satisfy the condition. So you will get the first /subtitles/ and the last … Read more
Try this. There are definitely no loops here (assuming String.length does not iterate and String.substring does not make a copy), not even behind the scenes, except in the printing of course. static int nSpaces ( String s ) { int n = 0; if ( s.length() > 0 ) { if ( s.length() > 1 … Read more
Before anything, make your tuple into a list. A list is easier to work with as it is mutable (modifiable), whereas a tuple is not. >>> dates = list((’01/01/2009′, ’02/01/2009′, ’03/01/2009′, ’04/01/2009′)) >>> dates [’01/01/2009′, ’02/01/2009′, ’03/01/2009′, ’04/01/2009′] Request number one, strings of integers: >>> answer1 = [item[:2] for item in dates] # Here we … Read more
The command str=”str1″,’str2′ creates a tuple in the variable str, and is equivalent to doing str = (‘str1’, ‘str2’) Note that this is probably the underlying cause of your confusion… you are creating a tuple but putting it in a variable with a name that indicates you expected a string. When you do str1 = … Read more
