c++ - create personal library using template(linux platform)

/*create own personal library in c++, using gcc compiler in linux platform.
atfirst create a source file and a header file. then create a main file to
include header file. here tem.cpp is source file and tem.h is header
file. main.cpp is main file.here tempalte is used instead of function definition. */
//template is a general case for functions for diff. datatypes as "int,float,double".
