With ghc6 a simple hello world program seems to come to about 370kB (523kB before strip). Hello world in C is about 4kB (9kB before strip). 回答1: With the development branch of GHC (anyone know exactly which version this was added in?): $ ghc - o hello hello . hs $ strip - p -- strip - unneeded -- remove - section =. comment - o hello - small hello $ du hello hello - small 700 hello 476 hello - small Add the -dynamic flag for a dynamically linked RTS: $ ghc - dynamic - o

How do this interact with small string optimization? Did they forget to add std::string too? 回答1: (Reposting from comment) std::string is not a container – the fact that basic_string is not described in the Containers library chapter (§23) of the FDIS is a good clue. ;-] 文章来源

Mobileno = Convert.ToInt32(txmobileno.Text); error i amm getting while inserting in to database 回答1: Why on earth would you use an integer of any type to store a phone number? You can't meaningfully do any arithmetics on one and you lose all leading zeroes. Use a string instead. 回答2: An integer (Int32) is limited in the values it can store since it "only" uses 32 bits. It can store a value between 2,147,483,647 and -2,147,483,648. ( More information on MSDN ) The value represented by

Is workbench a real debugger but a watcher? what's its advantage over mathematica? How do you debug when you writting big or small codes? mabye workbench is for debugging small codes and

I need a loop as I have a list of more than 1000 matrices. I decide to use the code (from the answers) full_matrix [ rownames ( full_matrix ) % in % rownames ( small_matrix ), colnames ( full_matrix ) % in % colnames ( small_matrix )] <- small_matrix which worked fine in my case for a single matrix match. However, I have problems implementing this code into a loop for the list of matrices "small_matrix". Here my code: full_matrix
