hi,
I have a question regarding how to compare 2 different C source files(e.g. Text1.c, stub.c), which contain names of function calls.

My objective is to compare these 2 source file and get rid of any occurances of the function names inside Text1.c(reference file) from stub.c(working file)

The problem I have is that my code doesn't seem to be able do that. The script seems to just copy the all same function calls that I have in stub.c, without removing any occurance of the repeated function calls found in Text1.c 

#!/user/bin/perl -w

#note: %hash1 contains modified functions,
#which has been extracted from a C source file(Test1.c).
#this hash is used for referencing purposes

@array = %hash1;


#initiate a loop counter
$loop = 0;

#using for loop to get rid of new line in the array
for (@array){
$array[$loop] =~ s/\n//;
$loop++
}

#opening file for writing  
open (Done, ">sim.c") or die "Can't open sim.c :$!\n";

#initiating a new hash and a string for later use
%hash2;
$done;

#a for loop to help popping all the elements in array. 

for (0..6){        
$fish = pop @array;
$fish = pop @array;

#opening of working file, which is to be compared with
#the reference array(%hash1)
open (Local, "stub.c") or die "Can't open stub.c :$!\n";

for $local(<Local>){
$local =~ s/\n//;

#this is used to compare the 2 variable
#if there is no match, assign it as a key to a hash
unless ($fish eq $local){
$hash2{$local}++;
}

close Local;
}
}

#print each key of the hash to verify result
foreach $done ( keys %hash2){
print "$done\n";
}
