I have an array of strings. What I want is to remove from a string the character "," and the character "]" change it to "|".
string = 3.1321309062246026, 42.02829431948331],
and i want to get :
string = 3.1321309062246026, 42.02829431948331|
so i want to remove final "," but not the one in the middle. Also to change that ] to | . it has to change like this
3.1321309062246026,42.02829431948331|
Input
a="3.1321309062246026, 42.02829431948331],"
Code
p a.gsub(/\]/,"|").gsub(/,\z/,"")
Output
"3.1321309062246026, 42.02829431948331|"

What is a proper Regex code to allow special characters like . _ - in email field
I have this Regex right now /^[a-zA-Z0-9]+#[a-zA-Z0-9]+\.[A-Za-z]+$/,
The above Regex only allow e-mails such as joedow#gmail.com
joe.dow#gmail.com does not work
How can I fix this ?
Just add those characters to the Regex:
^[a-zA-Z0-9\._-]+#[a-zA-Z0-9]+\.[A-Za-z]+$
https://regex101.com/r/xKkKIQ/1
This will make the regex consider ., _ and -. If you want any other characters, add them in the same way.

I have a challenge question like "What is your favorite movie?". There could be any question like this. I need last word of the question i.e. movie. without question mark.
Try this
String question = "What is your favorite movie";
String lastWord = question .substring(question .lastIndexOf(" ")+1);
When you select the element containing your challenge question, you can call .getText() (in Java; similar in other languages) to get the text inside. Then, you can use regular expressions or substring utilities in your language to strip out the last word.

When using C programming language, I have no idea how to put a user input to an array.
I need to get integers from the user in from of:
printf("Enter numbers. Separate each by a comma: ");
How can I put each number into an array?
This is a very helpful link
Also look up this too for clarification on Console.Read & Console.Readline
Difference between Console.Read() and Console.ReadLine()?

I want to split a string i have "msg 10 2" into different strings & ints. so instead of having
msg 10 2
I can take each as a seperate parameter can print:
msg
10
2
I use the variable to define a message:
char msg[30] = "msg 10 2";
I then want to take each field as seperate values/parameters.
Thanks
If you know your string will always follow the format string int int, then you could also use sscanf.
Use strtok (which you already tagged) and atoi.
