Multi-language hybrid programming is mainly a program written in one language to call a routine written in another language, and the data used is mainly passed through routine parameters, which rarely reflects the object-oriented programming idea. It is proposed to use the newly introduced modules of Fortran 90 to realize a new hybrid programming model of Fortran and C/C++ object-oriented. The example results show that C/C++ has direct access to data and routines in the Fortran module; Its own data and functions can also be encapsulated in a module for access by Fortran program units referencing the module.
