问题 Hy everyone, pls consider this small code, and help me to figure out, why it's not working? #include <stdio.h> #include <stdlib.h> void setup(int* helo) { helo = (int*) malloc(sizeof(int)); (*helo) = 8; } int main(int argc, char* argv[]) { int* helo = NULL; setup(helo); printf("Value: %s \n", (*helo)); getchar(); return 0; } 回答1: You are looking for one of two options here. You can either take the memory pointer allocation out of the equation, and pass the memory address of a standard

问题 I build a csv string from values I have in my DB. The final string is stored in my $csv variable. Now I offer this string for download, like this: header("Content-type: text/csv"); header("Content-Disposition: attachment; filename=whatever.csv"); header("Pragma: no-cache"); header("Expires: 0"); echo $csv; When I open this in Notepad++ for example, it says Ansi as UTF-8 . How can I chnage that to Ansi only? I tried: $csv = iconv("ISO-8859-1", "WINDOWS-1252", $csv); That did not change

问题 I am looking for a control code to create orange text in a terminal using ANSI or some other standard, is this possible? I only see yellow and red available, and I don't think you can mix red and yellow for the same character :) 回答1: Strictly speaking, no: ANSI never standardized anything (for a terminal's control sequences) which was called "orange". Some terminals can do this, but that lies outside the scope of the standards. xterm (see XTerm Control Sequences) uses control sequences

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . Where can I find the latest ANSI C standard document? 回答1: You can buy it here (ISO/IEC 9899:2011): http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=57853 Price is around USD 240.

问题 Is it possible to use Windows API ANSI functions with UTF-8 strings? For example, say I have a path encoded in UTF-8. Can I call CreateDirectoryA or CreateFileA and use a UTF-8 path, or do I have to perform some conversion before calling the functions? 回答1: No. Use MultiByteToWideChar to convert UTF-8 to UTF-16 and then call the wide character APIs such as CreateDirectoryW or CreateFileW . 回答2: An easier approach (than using raw Win32 API MultiByteToWideChar) would be to use ATL conversion

问题 I need to extract the text between 2 string patterns in c. Example: aaaaaa<BBBB>TEXT TO EXTRACT</BBBB>aaaaaaaaa PATTERN1=<BBBB> PATTERN2=</BBBB> Thanks. 回答1: Here is an alive example of how to do this #include <stdio.h> #include <string.h> int main(void) { const char *s = "aaaaaa<BBBB>TEXT TO EXTRACT</BBBB>aaaaaaaaa"; const char *PATTERN1 = "<BBBB>"; const char *PATTERN2 = "</BBBB>"; char *target = NULL; char *start, *end; if ( start = strstr( s, PATTERN1 ) ) { start += strlen( PATTERN1 ); if

问题 Somewhere I read (rephrased): If we compare a UTF-8 encoded file VS a UTF-16 encoded file, At some times, the UTF-8 file may give a 50% to 100% larger file size Am I right to say that the article is wrong because at all times , text encoded in UTF-8 will never give us more than a +50% file size of the same text encoded in UTF-16? 回答1: The answer is that in UTF-8, ASCII is just 1 byte, but that in general, most Western languages including English use a few characters here and there that

问题 I have a Ruby script that generates a UTF8 CSV file remotely in a Linux machine and then transfers the file to a Windows machine thru SFTP. I then need to open this file with Excel, but Excel doesn't get UTF8, so I always need to open the file in a text editor that has the capability to convert UTF8 to ANSI. I would love to do this programmatically using Ruby and avoid the manual conversion step. What's the easiest way to do it? PS: I tried using iconv but had no success. 回答1: ascii_str =
