Here's an example of a function that takes an array of Person structures as input: fortranCopy SUBROUTINE ProcessPeople(people, num_people) TYPE(Person), INTENT(IN) :: people(:) INTEGER, INTENT(IN) :: num_people ! ... function body ... END SUBROUTINE ProcessPeople SUBROUTINE ProcessPeopl...

With OOP-style (Array of Structures) the code may be traversing levels of code to get to the necessary operations on scalar variables. Using "traditional" Fortran (Structure of Arrays), the code generally has (relatively) immediate access to vectors of data suitable for SIMD...
it can be useful to look at how theaddressof an array element is computed. Each array will have some memory address assigned to the beginning of the array, that is element (1,1). The address of element (i,j) is then given by ...
The elements and fields of arrays and structures must be compatible. You cannot pass arrays, character strings, or structures by value. You can pass arguments by value from f77 to C, but not from C to f77, since %VAL() is not allowed in a Fortran dummy argument list.FORTRAN...

II.C.5 Abstract Data Types and Data Structures In Section II.B.2 the concept of derived-data types was introduced. When one of these is denned, it is further possible to define the meanings associated with operations and assignments on objects of that type or between an object of that ty...
1. Where can I find the difference of array structures between FORTRAN and C? 2. Are there any differences of other data structure between FORTRAN and C, such as link, and so on? 3. What is the mean of elementiAllocated? I have tried to change it to zero and found the output ...
For example, an array of INTEGER*2 data aligns on a 2-byte boundary. The exception to this rule is that aligment of REAL*2 arrays is on a 4-byte boundary. Structures and Unions align according to the alignment of the most restricted data type of the structure or union. In the next ...
