A common piece of code I use for simple string splitting looks like this: inline std::vector<std::string> split(const std::string &s, char delim) { std::vector<std::string> elems; std::stringstream ss(s); std::string item; while(std::getline(ss, item, delim)) { elems.push_back(item); } return elems; } S...
Hello, I'm sure I'm just doing something stupid here, but I can't quite figure out what it is. When I try to run this code: #include <iostream> #include <string> #include <sstream> using namespace std; int main(int argc, char *argv[]) { string s("hello"); istringstream input(s, istringstream::in); string s2; input >> s2; cou...
Hi I need to read different values stored in a file one by one. So I was thinking I can use ifstream to open the file, but since the file is set up in such a way that a line might contain three numbers, and the other line one number or two numbers I'm not sure how to read each number one by one. I was thinking of using stringstream but...
I am reading a file in the following format 1001 16000 300 12.50 2002 24000 360 10.50 3003 30000 300 9.50 where the items are: loan id, principal, months, interest rate. I'm not sure what it is that I am doing wrong with my input string stream, but I am not reading the values correctly because only the ...
Hello I've got a problem with the following code snippet. It is related to the stringstream "stringstream css(cv.back())" bit. If it is commented out the program will run ok. It is really weird, as I keep getting it in some of my programs, but if I just create a console project the code will run fine. In some of my Win32 programs i...
I have an application developed under Linux with GCC 4.2 which makes quite heavy use of stringstreams to wrap and unwrap data being sent over the wire. (Because the Grid API I'm using demands it). Under Linux everything is fine but when I deploy to SunOS (v5.10 running SPARC) and compile with GCC 3.4.6 the app hangs when it reaches the p...
I have a file which contains three integers per line. When I read the line I use a stringstream to separate the values, but it only reads the first value as it is. The other two are read as zero's. ifstream inputstream(filename.c_str()); if( inputstream.is_open() ){ string line; stringstream ss; while( getline(inputstream...
I recently discovered that std::strstream has been deprecated in favor of std::stringstream. It's been a while since I've used it, but it did what I needed to do at the time, so was surprise to hear of its deprecation. My question is why was this decision made, and what benefits does std::stringstream provide that are absent from std:...
In this slice of code I get an output of bbb 55 66 77 88 aaa the output I expect and want is bbb 55 66 77 88 bbb because I reassign ss from log[0] to log[1]. So my question is why is the output different from what I expect and how do I change it to what I want? int w,x,y,z; stringstream ss (stringstream::in | stringst...
When I use getline, I would input a bunch of strings or numbers, but I only want the while loop to output the "word" if it is not a number. So is there any way to check if "word" is a number or not? I know I could use atoi() for C-strings but how about for strings of the string class? int main () { stringstream ss (stringstream::in | ...
I want to know if it is possible to transform a std::vector to a std::stringstream using generic programming and how can one accomplish such a thing? ...
I'm having problem with stringstream.my visual studio nor linux g++ can understand stingstream. I've added sstream but it does'nt solve anything. I've worked with it before and really don't know what's up with it now? #include <sstream> #include <stdlib.h> #include "SymbolTable.cpp" #include "setjmp.h" using namespace std; jmp_buf *bfj;...
I cannot get the following stringstreamm to compile stringstream qss; qss.operator << "some text " ::stringstream.operator << DDateTime::date2Oracle(dFrom) ::stringstream.operator << " more text " ::stringstream.operator << DDateTime::date2Oracle(dUntil); If I just use the << operator without the ::stringstream.operatorit complain...
Hello, so I am trying to insert the character, which i got from a string, to another string. Here I my actions: 1. I want to use simple: someString.insert(somePosition, myChar); 2. I got an error, because insert requires(in my case) char* or string 3. I am converting char to char* via stringstream: stringstream conversion; char* myC...
How can I post-initialize an stringstream inside a map? Is it even possible or do I have to create a stringstream*? std::map<std::string, std::stringstream> mapTopics; if(mapTopics.end() == mapTopics.find(Topic)) { mapTopics[Topic] = std::stringstream(""); // Post Initialize <--- } std::map<std::string, std::stringstream>::iterat...
I have a wstring stream that I'm using as sort of a buffer in my class and it is used by a good portion of the methods in this class. However, when I try to do something like this: #include <sstream> class foo { public: void methodA(int x, int y); // Uses mBufferStream void methodB(int x, int y); // Uses mBufferStream pri...
Hello, I think the title says pretty much everything, hehe. I would like you to tell me when to use std::istringstream, std::ostringstream and std::stringstream and why I shouldn't just use std::stringstream in every scenario (like are there any runtime performance issues?). Thanks! PS: I have a third, less important question. Is ther...
I've got this (incorrect) sample code for getting a value out of stringstream and storing it in a byte-sized variable (it needs to be in a single byte var, not an int): #include <iostream> #include <sstream> using namespace std; int main(int argc, char** argv) { stringstream ss( "1" ); unsigned char c; ss >> c; cout ...
I'm having same issue in Ubuntu 10.04 using gcc4.4, the same code works fine on RH 5.5 using gcc4.1 #include <sstream> #include <iostream> int main(int argc, char** argv) { std::stringstream myStream; myStream << "-123"; unsigned int myUInt; myStream >> myUInt; if(myStream.fail()) { std::cout << "FAILED" << std::endl; ...
I have stringstream object ss1 now I would like to create another copy from this one. I try this std::stringstream ss2 = ss1; or std::stringstream ss2(ss1) neither works The error message is like this std::ios::basic_ios(const std::ios &) is not accessible from bsl::basic_stringstream, bsl::allocator>::basic_stringstream(cons...
