How to use templates from one File in another File in c++?

  • 772

I have a file with the extension A.cpp which has templates that I would like to use in the B.cpp file . I tried putting the following in B.cpp :

#include "A.cpp"

But I get the following error:

C:\Users\friky\Documents\Octavo Semestre\Inteligencia Artificial\Arbol.cpp  In function 'int main(int, char**)':
3   5   C:\Users\friky\Documents\Octavo Semestre\Inteligencia Artificial\Arbol.cpp  [Error] redefinition of 'int main(int, char**)'

    I think it's because by including the "A.cpp" file there is an ambiguity between the "main" functions of each.

    I recommend you put what you want to use in those two files in a "Templates.h" file and import it in both.

    I hope it helps.

    A greeting.
