previous declaration of 'function' was here in C - Stack Overflow

On my version of linux there is a getline function supplied by the C library (part of the POSIX standard I think). You can't have two functions with the same name in C, and this is your problem. Try renaming your version of getline to my_getline (both where you declare/define it and where you use it). Share Follow answered Nov 4, 2012 at 2:33

header - C++ getline won't work with int? - Stack Overflow

1 Answer. The version of std::getline you are trying to use there does not accept an int as a argument. See the function marked 2 (C++11) for the function you are trying to call here. std::istringstream can be included from sstream. I would add a std::endl (or new line) to the final print out to make it appear nicer as well.

C Language Tutorial => Get lines from a file using getline()

Another option is getdelim (). This is the same as getline () except you specify the line ending character. This is only necessary if the last character of the line for your file type is not '\n'. getline () works even with Windows text files because with the multibyte line ending ( "\r\n") '\n'` is still the last character on the line.

How to use std::getline() in C++? | DigitalOcean

Basic Syntax of std::getline () in C++ This function reads characters from an input stream and puts them onto a string. We need to import the header file <string>, since getline () is a part of this file. While this takes template arguments, we’ll focus on string inputs (characters) , since the output is written to a string.

getline (string) in C++ - GeeksforGeeks

The C++ getline () is a standard library function that is used to read a string or a line from an input stream. It is a part of the <string> header. The getline () function extracts characters from the input stream and appends it to the string object until the delimiting character is encountered.

getline(3) - Linux manual page - Michael Kerrisk

RETURN VALUE top. On success, getline () and getdelim () return the number of characters read, including the delimiter character, but not including the terminating null byte ('\0'). This value can be used to handle embedded null bytes in the line read. Both functions return -1 on failure to read a line (including end-of-file condition).

How do you getline a float or int? - C++ Forum -

5. 6. 7. template <typename T> inline T ToNumber (const string& text) { std::stringstream ss (text); T result; return ss >> result ? result : 0; } EDIT: The same result and side behaviour is achived by using atoi function, but it is not template and works on integral values, and because OP asked for generics I gave him a template :)

Using getline to read until a number - C++ Forum -

Yanson (885) The easy solution would be to change the input file so the number is read first. Then you can use getline to get the rest of the line. Another way would be to mark the end of the string with a ':' then use. getline (ifstream, string, ':'); to input the string. I don't know of a way getline could be used to read up to a number, but ...

std::getline -

Return value. input [] NoteWhen consuming whitespace-delimited input (e.g. int n; std:: cin >> n;) any whitespace that follows, including a newline character, will be left on the input stream.Then when switching to line-oriented input, the first line retrieved with getline will be just that whitespace. In the likely case that this is unwanted behaviour, possible solutions include:

Getline in C++ – cin getline() Function Example -

This is an inbuilt function that accepts single and multiple character inputs. When working with user input in C++, the cin object allows us to get input information from the user. But when we try to log out the user's input that has multiple values, it only returns the first character.
