a program to count the repeat numbers in the file

(OP)
I am learning tcl/tk and my first task is to write a program to count the repeat number in the second column of this file with content

January 4000 300 200
February 2000 100 0
March 4000 50 10
April 4000 120 300
May 1000 100 0
June 2000 0 0
July 400 1 1
August 4000 200 100
September 2000 100 200
October 0 0 0

Then the program will write to an output file with content

January 4000 300 200 1
February 2000 100 0 1
March 4000 50 10 2
April 4000 120 300 3
May 1000 100 0 0
June 2000 0 0 2
July 400 1 1 0
August 4000 200 100 4
September 2000 100 200 3
October 0 0 0 0

Notice that the last column has been added and it counts the number in second column (from the left) if they are repeat .
It is difficult for me so I would like to have your help.
Regards
Tony

RE: a program to count the repeat numbers in the file

Hi

Your explanation not covers May and October's 0, so I ignored them for now :

CODE --> Tcl

set fil [open "tpham1002002.txt"]

while {! [eof $fil]} {
set line [gets $fil]
set col2 [lindex $line 1]
if {$col2!=""} {
if {[array get count $col2]==""} { set count($col2) 0 }
incr count($col2)
lappend line $count($col2)
}
puts $line
}

close $fil
