Can someone please help me with this SHELL script?
I need to create a script that gets a positive number n as an argument. The script must calculate the factorial of its argument. In other words, it must calculate n!=1x2x3x...xn. Note that 0!=1.
Here is a start but I have no clue how to... (3 Replies)
I'm semi new to unix/linux and am trying to convert a program I wrote in C++ to a bash script. It's a program that prints Fibonacci's series. I have found scripts that will do it, but I'm trying persistently to get this one to work. The problem occurs when I try to return a value from the function.... (3 Replies)

Hi all,
While doing some checks I found a kind of interesting arithmetic factorial chart with sed, sharing this may be simple but thought to share,
# n=20;for i in `seq $n`;do printf "`seq $i|xargs|sed 's/ /*/g'`= ";echo "`seq $i|xargs|sed 's/ /*/g'`"| bc;done
1= 1

MPI_File_write_all_begin(3OpenMPI)MPI_File_write_all_begin(3OpenMPI)NAME
MPI_File_write_all_begin - Writes a file starting at the locations specified by individual file pointers; beginning part of a split collec-
tive routine (nonblocking).
SYNTAX
C Syntax
#include <mpi.h>
int MPI_File_write_all_begin(MPI_File fh, void *buf,
int count, MPI_Datatype datatype)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_FILE_WRITE_ALL_BEGIN(FH, BUF, COUNT, DATATYPE, IERROR)
<type> BUF(*)
INTEGER FH, COUNT, DATATYPE, IERROR
C++ Syntax
#include <mpi.h>
void MPI::File::Write_all_begin(const void* buf, int count,
const MPI::Datatype& datatype)
INPUT /OUTPUT PARAMETER
fh File handle (handle).
INPUT PARAMETERS
buf Initial address of buffer (choice).
count Number of elements in buffer (integer).
datatype Data type of each buffer element (handle).
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_File_write_all_begin is the beginning part of a split collective, nonblocking routine that attempts to write into the file associated
with fh (at the current individual file pointer position maintained by the system) a total number of count data items having datatype type
from the user's buffer buf. The data is written into those parts of the file specified by the current view.
NOTES
All the nonblocking collective routines for data access are "split" into two routines, each with _begin or _end as a suffix. These split
collective routines are subject to the semantic rules described in Section 9.4.5 of the MPI-2 standard.
ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI:Exception object.
Before the error value is returned, the current MPI error handler is called. For MPI I/O function errors, the default error handler is set
to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may
be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
