convert cpp program to c shell script ?
Hi guys
I tried to convert this c++ code to c shell script but there are some bugs and I don't know how to solve it.
This code prints the three variables in decreasing order:

Code:
int main()
{
int x,y,z;
cin >> x >> y >>z;

if ( x < y )
	if ( x < z )
		if ( y < z )
			cout << x <<"  " << y <<"  "<<  z << endl;
		else
			cout << x <<"  "<<  z <<"  "<<  y << endl;
	else
		cout << z <<"  "<< x <<"  "<< y << endl;
else
	if ( y < z )
		if ( x < z )
			cout << y <<"  "<< x <<"  "<< z << endl;
		else
			cout << y <<"  "<< z <<"  "<< x << endl;
	else
		cout << z <<"  "<< y <<"  "<<x << endl;

return 0;

}

Here is my try:


Code:
#!/bin/csh

if ( $1 < $2 ) then
	if ( $1 < $3 ) then
		if ( $2 < $3 ) then
			echo $1"  "$2"  "$3
		else
			echo $1"  "$3"  "$2
	else
		echo $3"  "$1"  "$2
else
	if ( $2 < $3 ) then
		if (  $1 < $3 ) then
			echo $2"  "$1"  "$3
		else
			echo $2"  "$3"  "$1
	else
		echo $3"  "$2"  "$1

       subroutine slasrt (ID, N, D, INFO)
	   SLASRT sorts numbers in increasing or decreasing order.

Function/Subroutine Documentation
   subroutine slasrt (characterID, integerN, real, dimension( * )D, integerINFO)
       SLASRT sorts numbers in increasing or decreasing order.

       Purpose:

	    Sort the numbers in D in increasing order (if ID = 'I') or
	    in decreasing order (if ID = 'D' ).

	    Use Quick Sort, reverting to Insertion sort on arrays of
	    size <= 20. Dimension of STACK limits N to about 2**32.

       Parameters:
	   ID

		     ID is CHARACTER*1
		     = 'I': sort D in increasing order;
		     = 'D': sort D in decreasing order.

	   N

		     N is INTEGER
		     The length of the array D.

	   D

		     D is REAL array, dimension (N)
		     On entry, the array to be sorted.
		     On exit, D has been sorted into increasing order
		     (D(1) <= ... <= D(N) ) or into decreasing order
		     (D(1) >= ... >= D(N) ), depending on ID.

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
		     < 0:  if INFO = -i, the i-th argument had an illegal value
