[Fortran] syntaxhighlighter_viewsource syntaxhighlighter_copycode

program main
    implicit none
    !自定义类型
    type distance
        real::m,cm,inch
    end type
    !申明自定义类型
    type(distance)::a
    write(*,*)"输入公尺(m)"
    read(*,*)a%m
    a%cm=a%m*100
    a%inch=a%m*39.3700787
    write(*,*)a%m,"m"
    write(*,*)a%cm,"cm"
    write(*,*)a%inch,"inch"
end program

1.创建自定义类型必须包含在

[Fortran] syntaxhighlighter_viewsource syntaxhighlighter_copycode

type 
end type

2.自定义类型中元素的访问需要用%
