I'm trying to use istringstream to split a simple string into a series of integers: #include <string> #include <iostream> #include <sstream> #include <vector> using namesp...

So istringstream copies the contents of a string when initialised, e.g string moo("one two three four"); istringstream iss(moo.c_str()); I was wondering if there's a way to make std::istringstre...

The std::stringstream initialization constructor accepts const string& as a parameter: explicit stringstream (const string& str, ios_base::openmode which = ios_base::in | ios_base::out); ...

I am coding in Eclipse and have something like the following: #include <ftream> #include <iostream> void read_file(){ char buffer[1025]; std::istringstream iss(buffer); } However,...

I have a function do_something that reads unsigned characters from a stream. The stream can be created from a file given the file name. Or it can be created from the given string by considering it ...

I'm trying to set the internal buffer of an input stream, but my implementation in C++17 doesn't implement pubsetbuf() for istringstream. I've tried some other techniques, but they are slow or cop...

When would I use std::istringstream, std::ostringstream and std::stringstream and why shouldn't I just use std::stringstream in every scenario (are there any runtime performance issues?). Lastly, ...

Data saved in my file is (white spaces added at both beginning and end on purpose for this test): 1 2 3 Loading the data using the code below with or without "std::ws" does not cause any differ...

I came across a difference in behavior, between gcc (4.9.2) and clang (3.5.0), which surprised me. When I try to feed an unsigned int from an std::istringstream initialized with a negative value (...

I want to have a variable of type istream which can hold either the contents of a file or a string. The idea is that if no file was specified, the variable of type istream would be assigned with a ...

The following code splits the provided string/line down to the characters. Why does the loop repeats that last string twice? How to fix it? #include <iostream> #include <vector> #inclu...

In the following function, I try to see if a string s is convertible to type T by seeing if I can read a type T, and if the input is completely consumed afterwards. I want template <class T&gt...

I'm trying to extract different types of data from a string. void readHeader(char buf[BUFFSIZE]) { std::istringstream hdr(buf); __uint128_t id_client; hdr >> id_client; // doesn't compil...

Why does my program not output: 10 1.546 ,Apple 1 instead of 10 1 <empty space> here's my program: #include <iostream> #include <string> #include <sstream> using na...

currently I am using a boost char array boost::array<char, 512> received_data; std::istringstream ss_(received_data.data()); but what if my received_data was a std::vector<char> rec...

So, I've been trying to figure out, how to wait for data from a C++ stringstream (for instance), without being constantly checking if data is there, which is quite CPU consuming. I'm perfectly abl...

I have a code for reading files with float numbers on line stored like this: "3.34|2.3409|1.0001|...|1.1|". I would like to read them using istringstream, but it doesn't work as I would expect: s...

Can I persuade operator>> in C++ to read both a hex value AND and a decimal value? The following program demonstrates how reading hex goes wrong. I'd like the same istringstream to be able to...
