Here is my code:
A variable declaration has its meaning at the time of compilation only, compiler needs actual variable definition at the time of linking of the program. A variable declaration is useful when you are using multiple files and you define your variable in one of the files which will be. Nov 13, 2005 But your compiler isn't complaining about multiple.declarations. It is complaining about multiple.definitions. You can.declare. a function multiple times but it should only be.defined. once. Each.c source file includes the associated header as does the main.c file which calls the functions. I know I have done this before. Sep 16, 2011 in the past I've been able to create header file that would contain a function prototype. And insert its definition into a seperate cpp file. Which I could then run in another cpp file as long as included the header file at the beginning. It only works in Dev-C if I make a project. In 1989, C 2.0 was released, followed by the updated second edition of The C Programming Language in 1991. New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C Reference Manual was published. This work became the basis for the.
I'm simply trying to find out whether a command given by the user is in an array of commands, and, if it is, I want the index.
This is the error:
multiple definition of `in_array(std::string*, std::string)'
I don't have this defined anywhere else, so I thought perhaps there is an existing function called 'in_array'. So I renamed my function to 'in_array_c'. Now the error message is:
multiple definition of `in_array_c(std::string*, std::string)'

#include 'action.cpp'
This tells the preprocessor to paste the contents of the text file 'action.cpp' into this position, just as if you had yourself manually typed it in at that position.
So, you have a definition of the function in action.cpp, and a definition of the function in main.cpp

Can you show us the other files (or rather a minimal version of them that still produces the same error message) in the project and how you build the project?

Dev-C++ is a free full-featured integrated development environment (IDE) distributed under the GNU General Public License for programming in C and C++. It is written in Delphi.
It is bundled with, and uses, the MinGW or TDM-GCC 64bit port of the GCC as its compiler. Dev-C++ can also be used in combination with Cygwin or any other GCC-based compiler.[1]
Dev-C++ is generally considered a Windows-only program, but there are attempts to create a Linux version: header files and path delimiters are switchable between platforms.
Devpaks[edit]
An additional aspect of Dev-C++ is its use of DevPaks: packaged extensions on the programming environment with additional libraries, templates, and utilities. DevPaks often contain, but are not limited to, GUI utilities, including popular toolkits such as GTK+, wxWidgets, and FLTK. Other DevPaks include libraries for more advanced function use. Users of Dev-C++ can download additional libraries, or packages of code that increase the scope and functionality of Dev-C++, such as graphics, compression, animation, sound support and many more. Users can create Devpaks and host them for free on the site. Also, they are not limited to use with Dev-C++ - the site says 'A typical devpak will work with any MinGW distribution (with any IDE for MinGW)'.
Development status[edit]
From February 22, 2005 to June 2011 the project was not noticeably active, with no news posted nor any updated versions released. In a 2006 forum post, lead developer Colin Laplace stated that he was busy with real-life issues and did not have time to continue development of Dev-C++.[2]
There are two forks of Dev-C++ since then: wxDev-C++ and the Orwell version.
wxDev-C++ is a development team that has taken Dev-C++ and added new features such as support for multiple compilers and a RAD designer for wxWidgets applications.
On June 30, 2011 an unofficial version 4.9.9.3 of Dev-C++ was released by Orwell (Johan Mes), an independent programmer,[3] featuring the more recent GCC 4.5.2 compiler, Windows' SDK resources (Win32 and D3D), numerous bugfixes, and improved stability. On August 27, after five years of officially being in a beta stage, version 5.0 was released.[4] This version also has its own separate SourceForge[5] page since version 5.0.0.5, because the old developer isn't responding to combining requests. On July 2014, Orwell Dev-C++ 5.7.1 was released featuring the more recent GCC 4.8.1 which supports C++11.
Notable uses[edit]
On May 4, 2015, The Singapore Prime Minister Lee Hsien Loong posted his Sudoku solver program in C++ on Facebook. In his screen shot, he's using Microsoft Windows and Dev-C++ as his IDE.[6]
