Leverage Modern Fortran Features

Use Fortran 90/95/2003/2008/2018 Features:

• Array Operations: Modern Fortran offers powerful array operations. Utilize array slicing and intrinsic functions like sum, maxval, and minval to write concise and efficient code.
• Modules: Use modules to encapsulate data and procedures, promoting code reuse and modularity. Modules also allow you to manage visibility and scope of variables and procedures.
• Derived Types and OOP: Define custom types (derived types) and use object-oriented programming features like type extension and type-bound procedures for more structured and maintainable code.

Example:

fortranCopy codemodule math_utils
    implicit none
contains
    function dot_product(a, b) result(prod)
        real, dimension(:), intent(in) :: a, b
        real :: prod
        prod = sum(a * b)
    end function dot_product
end module math_utils

program example
    use math_utils
    implicit none
    real, dimension(3) :: x = [1.0, 2.0, 3.0]
    real, dimension(3) :: y = [4.0, 5.0, 6.0]
    print *, 'Dot product:', dot_product(x, y)
end program example
