Expected unqualified-id before 'return'?

[fhasdkfhadlksfjhalsdkfh12]

I've been working on a decryption program for another encryption program I made. It isn't finished, and when I try to compile it to test it, it gives me the error "expected unqualified-id before 'return'" right at the line where "return 0;" is. I am using Xcode for mac os, which is the same as g++ 4.0 for Unix/Linux. I can't seem to figure this out, and I can't test anything until it's fixed.

Any ideas?

Here's the code:
-----------------------
#include <iostream>
#include <fstream>
#include <cstdio>
#include <bitset>
using namespace std;

int main () {

char password[32];
char file[100];
char filedata[8448];
bool filebin[8448];
bool key[32][8];
bool splitholder[1056][8];
int length;
int totiterations;
int iteration = 1;
bool passwordbin[32][8];
bool holder[32][1024][8];

//Get information from user
cout << "Type in the name and location of the .spir file you wish to decode.\n";
cin >> file;
fstream inputfile;
inputfile.open( file, ios::in | ios::binary);
while(inputfile >> filedata)
// cout << filedata;
inputfile.close ();
//cout << "\n\n";
int a = 0; /*Convert data from file into binary*/
while(a<8448){
if(!filedata[a]){
break;
}
if(filedata[a]=='0'){
filebin[a]=false;
}
else
{
filebin[a]=true;
}
// cout << filebin[a];
a++;
}
cout << "\n\n";
cout << "\n\nType in the password for the file.";
cin >> password;
length = strlen(password );

//Split the file into bytes
int b = 0,c = 0;
while(b<1056){
if(!filedata[b*8]){
break;
}
c = 0;
while(c<8){
splitholder[b][c] = filebin[(b*8)+c];
// cout << splitholder[b][c];
c++;
}
b++;
// cout << "\n";
}

//Separate the key from the file

//cout << length << "\n\n";
b = 0;
while(b<length) {
c = 0;
while(c<8){
key[b][c] = splitholder[b][c];
// cout << key[b][c];
c++;
}
b++;
cout << "\n";
}

//Shift the file to cover key
b = 0;
while(b<1024){
c = 0;
while(c<8){
splitholder[b][c] = splitholder[b+length][c+length];
// cout << key[b][c];
c++;
}
b++;
cout << "\n";
}

//Erase extra data

b = 1024;
while(b<1056){
c = 0;
while(c<8){
splitholder[b][c] = false;
c++;
}
b++;
cout << "\n";
}

//Convert the password into binary
int p = 0;
int e = 0;
while(e<length) {
int f = 0;
while(e<8){
++ e;
if((password[p]&(1 << e) ? '1' : '0')=='1'){
passwordbin[p][e]=true;
}else{
passwordbin[p][e]=false;
}
f++;
cout << passwordbin[p][e];
}
p++;
}

//Decode the key
bool d,o;
b = 0;
while(b<length) {
c = 0;
while(c<8){
d = key[b][c];
o = passwordbin[b][c];
key[b][c] = (d||o)&&!(d&&o) ;
c++;
}
b++;
}

//Decrypt the message
totiterations = length;
int f = 0,g = 0;
bool x,y,z;
while(iteration <totiterations) {
f = 0;
while(f<1024)
g = 0;
while(g<8){
if(iteration = 0){
holder[iteration][f][g] = splitholder[f][g];
}
if(f=0){
y=holder[iteration][f][g];
x=key[iteration][g];
z=(x||y)&&!(x&& y);
holder[iteration+1][f][g] = x;
holder[iteration+1][f+1][g] = z;
}
else{
y=holder[iteration][f][g];
x=holder[iteration+1][f][g];
z=(x||y)&&!(x&& y);
holder[iteration+1][f+1][g] = z;
}
g++;
}
f++;
}
iteration++;
}

//end the program
return 0;
}

P.S. I know the code is messy and inefficient, but it worked up until now.

One kind advice..!! Please write your code in CODE tags as given in instructions (right side when you write new thread) so it soesn't become messy :))

BTW the problem is one extra } that you have added before return 0. I think it is generating this error. Just remove it to get rid of the error!!!
