INTEGER, LOGICAL and REAL

In this section:

• Mixed language programming
• Basic data types
• Arrays
• Character strings
• Calling FTN95 from C/C++
• CHARACTER variables
• Arrays
• INTEGER, LOGICAL and REAL
• Calling C/C++ from FTN95
• Calling an FTN95 DLL from Visual Basic
• Mixing I/O systems in Fortran and C/C++

It is necessary to ensure that the data type of the C/C++ variable matches that of the FTN95 variable (see the table in Basic data types ). All parameters in the Fortran argument list will be passed by reference. You should therefore declare each argument as a pointer in C or as a reference variable in C++.
