The error is saying you didn’t provide a main() function. Looking at your code I see the following: int main(); This is a function declaration not a definition.

It is NOT possible unless the URL parameter is properly URL-encoded, so the “&” characters will be escaped in order not to be interpreted as field separators. The string should be encoded like this: String queryString = “AQB=1&v1=somev1data&v25=somev25data&URL=http%3A%2F%2Fwww.someurl.com%2Fconfigure%2Fgetvalues%2Frequest1%3Dreq1Passed%26data2%3DsomedataPassed&ce=UTF-8&ARB=1”; As it is formatted in your question, the string cannot be parsed successively. 2 solved How to … Read more

Base 4 requires exactly 2 bits, so it’s easy to handle efficiently. my $uvsize = length(pack(‘J>’, 0)) * 8; my %base4to2 = map { $_ => sprintf(‘%2b’, $_) } 0..3; sub base4to10 { my ($s) = @_; $s =~ s/(.)/$base4to2{$1}/sg; $s = substr((“0” x $uvsize) . $s, -$uvsize); return unpack(‘J>’, pack(‘B*’, $s)); } This allows … Read more

In some sense, having just 2 parameters is “The Right Thing”. The unordered map is about some internal necessity of the algorithm. Why should user code … Read more

[Solved] if/else statement

I can’t try this because it’s a bit orphaned, but try the following (or at least the following idea). I was confused because your link didn’t actually include the code you posted. Try posting a jsfiddle with the code if you’re still having problems. Your ($(‘.active’).length>0) statement doesn’t need the >0 part – all no-zero … Read more
