问题 I've got a button which when clicked copies and appends the text from a GtkEntry widget into a GtkTextView widget. (This code is a modified version of an example found in the "The Text View Widget" chapter of Foundations of GTK+ Development .) I'm looking to insert a newline character before the text which gets copied and appended, such that each line of text will be on its own line in the GtkTextView widget. How would I do this? I'm brand new to GTK+. Here's the code sample: #include <gtk

问题 How do you add a new line to a c++ string? I'm trying to read a file but when I try to append '\n' it doesn't work. std::string m_strFileData; while( DataBegin != DataEnd ) { m_strFileData += *DataBegin; m_strFileData += '\n'; DataBegin++; } 回答1: If you have a lot of lines to process, using stringstream could be more efficient. ostringstream lines; lines << "Line 1" << endl; lines << "Line 2" << endl; cout << lines.str(); // .str() is a string Output: Line 1 Line 2 回答2: Sorry about the late

Inserting endline into a stringstream

阅读更多关于 Inserting endline into a stringstream

问题 We know that when inserting \n in a file stream, the appropriate end-of-line sequence for the system will be written to the file (e.g. \r\n for Windows). Does inserting an endline in a std::stringstream result in the system-appropriate end-of-line sequence being written to the string? For example: #include <sstream> int main() { std::ostringstream oss; oss << std::endl; std::string endlineSequence = oss.str(); bool isWindows = enlineSequence == "\r\n"; bool isOldMac = endlineSequence == "\r";

问题 I ran into an interesting problem today where my tests were failing consistently on the build machine when they worked just fine on my machine even using the same configuration. When I looked at the differences output by Assert.AreEqual in the failure dump, I couldn't see anything different. After a bunch of investigation, I came to find out that the verbatim string in the test case source code (which spanned multiple lines) was using CRLF on my machine, but using LF on the build machine,

Is \n multi-character in C?

阅读更多关于 Is \n multi-character in C?

问题 I read that \n consists of CR & LF. Each has their own ASCII codes. So is the \n in C represented by a single character or is it multi-character? Edit: Kindly specify your answer, rather than simply saying "yes, it is" or "no, it isn't" 回答1: Generally: '\n' is a single character, which represents a newline. '\r' is a single character, which represents a carriage-return. They are their own independent ASCII characters. Issues arise because in the actual file representation, UNIX-based systems
