Character strings

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++

C/C++ character strings are stored as a NULL (char(0)) terminated arrays of characters whilst Fortran characters strings are fixed length and are padded to the end of the array with spaces. It is important to take into consideration these different methods of storing strings when passing or receiving them as parameters.
