在CentOS系统下使用Fortran进行文件操作时,掌握一些技巧可以提高效率和代码的可靠性。以下是一些常用的Fortran文件操作技巧:

打开与关闭文件

读取文件

写入文件

文件操作进阶

错误处理

格式化读写

示例代码

以下是一些简单的Fortran代码示例,演示了如何进行文件操作:

读取文本文件

program read_text_file
  implicit none
  character(len100) :: filename
  character(len100) :: line
  integer :: unit, i

  print *, 'Enter the name of the file to read:'
  read(*, '(A)') filename

  open(unit=fileunit, file=filename, status='old', action='read')
  i = 0
  do
    read(fileunit, '(A)', iostat=i) line
    if (i /= 0) exit
    print *, line
  end do
  close(fileunit)
end program read_text_file

写入文本文件

program write_text_file
  implicit none
  character(len100) :: filename
  integer :: unit, i
  real :: data(10)

  print *, 'Enter the name of the file to write:'
  read(*, '(A)') filename

  print *, 'Enter the number of data points:'
  read(*, *) n

  do i = 1, n
    data(i) = i * 1.0
  end do

  open(unit=fileunit, file=filename, status='unknown', action='write')
  do i = 1, n
    write(fileunit, '(F6.2)') data(i)
  end do
  close(fileunit)

  print *, 'Data written to file:'
  do i = 1, n
    print *, data(i)
  end do
end program write_text_file

读取二进制文件

program read_binary_file
  implicit none
  character(len100) :: filename
  integer :: unit, i, n
  real, dimension(10) :: data

  print *, 'Enter the name of the binary file to read:'
  read(*, '(A)') filename

  open(unit=fileunit, file=filename, status='old', action='read', form='unformatted')
  read(fileunit) data
  close(fileunit)

  print *, 'Data read from binary file:'
  do i = 1, 10
    print *, data(i)
  end do
end program read_binary_file

通过这些技巧和示例代码,你可以在CentOS系统下更高效地进行Fortran文件操作,提升程序的性能和可靠性。
