expected unqualified-id before '{' token

[yuzgulasli]

hi, i have an expected unqualified-id before '{' token. the error message reads this:

Main.cc:6:1: error: expected unqualified-id before '{' token

This is the code:

 #include "iostream"
#include "string"
using namespace std;

int digit_count (int number);
{   
    int i = 0, number;
    while (number != 0) {
        number = number / 10;
        i++;
    }
    return i;
}

int main(void);
 {
    int i= 0, int roman, int result, int digit_count, int test_case, int number, int tmp;
    string roman[] = {"O","I","II","III","IV","V","VI","VII","VIII","IX"};
    string *result;
   string int number;
   
    cin >> test_case;
    while (i < test_case) {
        
        cin >> number;
        if ((number >= 0) && (number <= 2000000000)) {
            result = new string[digit_count(number)];
            int i = 0, tmp=number;
            while (int tmp) {
                result[i] = roman[tmp % 10];
                tmp = tmp / 10;
                i++;
            }
            i = digit_count(number);
            while (i >= 0) {
                cin >> result[i] >> " " >> endl;
                i--;
            }
        } else {
            
            return 1;
        }
        cin >> "\n";
        i++;
    }
}

What is the wrong?
