It is not on by default, so you must presumably have set it. Line wrapping is a really bad idea in a code editor IMO, I cannot think of a good reason to have it, but most. The word wrap plug-in I created is activated on all editors that implement the org.eclipse.ui.IEditorPart interface. This means that you can enhance almost every code editor of Eclipse with the soft wrapping feature (e.g. TextEditor, the JavaEditor of JDT, the C/C Editor of CDT or the TeXlipse LaTeX editor )!

Order of multi dimensional arrays in C/C++ is the opposite of FORTRAN.

Native FORTRAN layout (collumn-major order): INTEGER A(2,3)

a(1,1)

a(2,1)

a(1,2)

a(2,2)

a(1,3)

a(2,3)

Or INTEGER A(2,2,2)

a(1,1,1)

a(2,1,1)

a(1,2,1)

a(2,2,1)

a(2,2,1)

a(1,1,2)

a(2,1,2

a(1,2,2)

a(2,2,2)

Native C layout (row-major order) is NOT equivalent to the FORTRAN layout: int a[2][3];

a[0][0]

a[0][1]

a[0][2]

a[1][0]

a[1][1]

a[1][2]

Thus:

• Equivalent multidimension arrays:
  • FORTRAN 77: INTEGER I(2,3,4)
  • FORTRAN 90: INTEGER, DIMENSION(2,3,4) :: I
  • C: int i[4][3][2];
• Accessing a FORTRAN array in C:
  Native FORTRAN:
  Native C: C array a[3][2] memory layout:

  a[0][0]

  a[0][1]

  a[1][0]

  a[1][1]

  a[2][0]

  a[2][1]

• In FORTRAN 90, also check out the 'RESHAPE' directive.
• It is best not to re-dimension multi dimensional arrays within a function. Pass array size 'n' and declare array as x[n][];

Fortran subroutines are the equivalent of 'C' functions returning '(void)'.

Note: The entry point names for some FORTRAN compilers have an underscore appended to the name.This is also true for common block/structure names as shown above.

FORTRAN	C
CALL SUBRA( .. )	subra_( .. )

The GNU gfortran comiler flags '-fno-underscoring' (older f77: '-fno-underscore') and '-fno-second-underscore'will alter the default naming in the object code and thus affect linking.One may view the object file with the command nm (i.e.: nm file.o).

Note: The case in FORTRAN is NOT preserved and is represented in lower case in the object file. The gfortran compiler option '-fcase-lower is default.The older g77 compiler option '-fsource-case-lower' is also default.GNU g77 FORTRAN can be case sensitive with the compile option '-fsource-case-preserve'.

NOTE: When debugging with GDB, the Fortran subroutines must be referencedwith names as they appear in the symbol table. This is the same as the 'C'representation. Thus when setting a break point at the Fortran subroutine subra(), issue the comand 'break subra_'.

Man pages:

• nm - list symbols from object files
• gfortran - GNU FORTRAN compiler man page

All arguments in FORTRAN are passed by reference and not by value. Thus C must pass FORTRAN arguments as a pointer.

FORTRAN	C
call subra( i, x)	subra_( int *i, float *x)

Character variables:

• Linux and GNU compilers:When passing character strings, the length must follow as separate arguments which are passed by value.

  FORTRAN	C
  call subra( string_a, string_b)	len_a = strlen(string_a); len_b = strlen(string_a); subra_( char *string_a, len_a, char *string_b, len_b)

  I have also seen the passing of a data structure containing two elements, the character string and an integer storing the length. This is common with databases such as Oracle.

• Classic AT&T UNIX:
  When passing character strings, the length must be appended as separate arguments which are passed by value.

  FORTRAN	C
  call subra( string_a, string_b)	subra_( char *string_a, char *string_b, len_a, len_b)

C expects strings to be null-terminated. Thus character strings from FORTRAN which are passed back to 'C' should be null terminated with CHAR(0)

FORTRAN	C

Note:When using alternate returns to turn on/off an intlevel by returninga 1/0 you must use a FORTRAN wrapper to perform this function on theCSC Norwich mainframe. This is because the C compiler is old.

Buffering output: Your machine may be configured where the output buffering defaults for FORTRAN and C may be configured the same or differently. C output may be buffered buffered while FORTRAN may not. If so, execute a function initialization task to unbuffer C otherwise print statements for Cwill be output out of order and at the end.

Fortran common block and global C/C++ extern structs of same name are equivalent.Never use un-named common blocks! Reference variables in same order, same typeand with the same name for both C and FORTRAN.Character data is aligned on word boundaries.

Note: use of extern requires that the common block be referenced firstby FORTRAN. If referenced first by C then drop the extern. The externstatement states that it is trying to reference memory which has alreadybeen set aside elsewhere.

[Potential Pitfall]: Bytealignment canbe a source of data corruption if memory boundaries between FORTRAN andC/C++are different. Each language may also align structure data differently.One must preserver the alignment of memory between the C/C++ 'struct'and FORTRAN 'common block' by ordering the variables in the exact sameorder and exactly matching the size of each variable.It is best to order the variables from the largest word size down tothe smallest. Start with 'double' followed by 'float' and 'int'. Booland byte aligned data should be listed last.

Using GDB to examine alignment:

• Set a breakpoint in the C/C++ section of code which has visibility to the struct.
• While in a C/C++ section of code: (gdb) print &abc_.b
  $3 = (int *) 0x5013e8
• Set a breakpoint in the FORTRAN section of code which has visibility to the common block.
• While in a FORTRAN section of code: (gdb) print &b
  $2 = (PTR TO -> ( integer )) 0x5013e8

This will print the hex memory address of the variable as C/C++ andFORTRAN view the variable. The hex address should be the same for both.If not, the data will be passed improperly.

Forcing alignment with compiler arguments: Mixing IntelFORTRAN compiler and GNU g++: use the following compiler flags to forcea common memory alignment and padding to achieve a common double wordalignment of variables:

• Intel FORTRAN: -warn alignments -align all -align rec8byte
• Intel C/C++: -Zp8
• GNU g++: -Wpadded -Wpacked -malign-double -mpreferred-stack-boundary=8
  Example warning: warning: padding struct size to alignment boundary
• GNU g77: -malign-double

FORTRAN program calling a C function:

testF.f	testC.c

Compile:

• gfortran -c testF.f
• gcc -c testC.c
• gfortran -o test testF.o testC.o

Note: If there is use of C/C++ standard libraries you may have to include the following linking arguments: -lc or -lstdc++

Run: ./test

[Potential Pitfall]: If one does not terminate the string with NULL, the default with the new compilers (fort77 1.15 and gcc 4.5.2) and linker is to terminate the string with '004' which is EOT (end of transmission). Previously this was not required but it is now. This code (cc[ll--] = '0';) replaces the string terminating EOT character with a NULL.

C++ calling a FORTRAN function:

testC.cpp	testF.f

Compile:

• gfortran -c testF.f
• g++ -c testC.cpp
• g++ -o test testF.o testC.o -lg2c

Run: ./test

FORTRAN unit numbers can not be shared with 'C' and 'C' file pointers can not be used by FORTRAN. Pass data to a function (pick one language) which does the I/O for you. Use this function by both languages.

The GNU FORTRAN compilers have only ported a small subset of VAX extensions.The vast majority will require a clever re-write.

VAX Variable Format Expressions:

VAX expression	Ported to GNU FORTRAN

VAX intrinsic functions:

Many are not supported in GNU FORTRAN and require the creation of an equivalent library written in 'C'.

Return type	VAX FORTRAN intrinsic function	Argument type
Integer*4	NINT(arg) JNINT(arg)	Real*4
Integer*4	IDNINT(arg) JIDNINT(arg)	Real*8
Integer*2	ININT(arg)	Real*4
Integer*8	KNINT(arg)	Real*4
Integer*2	IIDNNT(arg)	Real*8
Integer*8	KIDNNT(arg)	Real*8
Integer*2	IIQNNT(arg)	Real*16
Integer*4	IQNINT(arg) JIQNNT(arg)	Real*16
Integer*8	KIQNNT(arg)	Real*16

Example: inint.c

• gcc -c inint.c
• gcc -c idnint.c
• ..
• Create library: ar -cvq libvax.a inint.o idnint.o ..

When mixing Fortran with C++, name mangling must be prevented.

The GNU FORTRAN compilers have supported the various standards over the years. The current (RHEL6 and Ubuntu 14.04) GNU gfortran compiler supports f95, f2003 and f2008 standards.By default, gfortran supports a superset of f95. Use the '-std=' flag to specify other levels of support.The older (RHEL4) GNU FORTRAN compiler supported the f77 standard.

Installation:

• Red Hat/CentOS: yum install gcc-gfortran
• Ubuntu/Debian: apt-get install gfortran

The Intel FORTRAN compilerhas become a popular FORTRAN compiler for Linux as it supports many ofthe FORTRAN extensions supported by the Compaq (old DEC vax) and SGIFORTRAN compilers. (i.e. 'structure', 'record', 'external', 'encode','decode', 'find', 'virtual', 'pointer', 'union', various intr8insicfunctions, I/O directives, ..)It links with object code generated by GNU gcc/g++ compilers as well astheir own Intel C/C++ compilers.

Sometimes when creating a C++ program, you run into a situation in which you want to compare one thing to a number of other things. Let's say, for example, that you took a character from the user and wanted to compare this to a number of characters to perform different actions. For now, let's just say that you have three commands which operate from the keys: 'h', 'e', and 'q'.

We can use an if-statement to check equality to 'h', 'e', and 'q' - remember that we use single quotes because we're dealing with chars, not strings. So let's just write the code in the way we're used to (and let's wrap a while loop around it so it keeps getting a character and acting upon what it was, because that makes our program slightly better and easier to test), using if-statements, like the following:

This program should be something you're comfortable with creating by this point, however your programmer instincts should also be kicking in and telling you that you shouldn't be repeating so much code here. One of the core principles of object orientated programming is DRY: Don't Repeat Yourself. In this program we're having to repeat a lot of code for the 'else if's including using ch every time we're doing a comparison.

The solution to this 'problem' is what this tutorial is all about: switch statements. These are essentially just a really nice way to compare one expression to a bunch of different things. They are started via the switch keyword, and from there comparisons are made using a case: syntax. It isn't easily described in words, so take a look at the syntax below:

The different cases essentially act as many if/else-ifs in a chain, and an 'else' type clause can be specified by using default:

This type of functionality should be reasonably easy to understand with if-statements securely under your belt, and so if you're feeling brave - try porting the basic program we created at the start of this tutorial to use if-statements. If you're not quite that brave, the cleaner and neater switch version of the code is below:
