error: expected unqualified-id before '{' token

I'm writing a program to make sure I understand the for statement. It is a program that computes the resistance of a network of resistors. I get the following error.

error: expected unqualified-id before '{' token

I am using code blocks on XP with the G++ compiler.

Code:

#include <iostream>

using namespace std;

int resitors; //amount of resistors the user enters
float resistance; //the output value, the resistance of the resistors in ohms
int resistor_value; //allows user to input value of resistors one at a time
int counter; //used to count

{
    resistance = 0;
    resist = 0; //initializing variables
    cout << "How many resistors?\n";
    cin  >> resistors;

    for  ( resitors < counter, ++counter) 
    {
        cout << "What is the resistence of the number " << counter << " resistor?\n";
        cin  >> resistor_value;

        resist += resistor_value;
    }

    resistance = (resist / resitors);

    cout << "The resistence is " << resistance << " ohms.\n";
    return(0);
}

Thanks in advance,

You need three things inside the parentheses of a for-statement. (Notice also that you get a line number for your error messages too.)

I have changed the for statement to,

for (counter = 0, resitors < counter, ++counter)

Still same error, error line is 10 which is the beginning bracket ({).

Okay. You still have one thing inside the parentheses. Note that things are separated with ; and not ,.

It seems to be none of your instructions are actually inside a function...

Yes, main is missing. Plus the variables should really be inside main, not globals.
