I Have a C++ Assignment I need help with. Please advise.

I am having troubles with my code. Can someone please advise the issue below.

The Question:

Write a C++ program that the Traffic Department can use when the owner of a car pays all his
outstanding road fines. The Traffic Department has a file called Fines.dat that keeps the
registration number and the road fine due for each traffic offence, one per line.
Your program should request the registration number from the user, read the contents of file
Fines.dat (shown below) line by line; if the road fine matches the registration number, display
the fine and calculate the total amount due for that registration number. At the same time all the
remaining registration numbers and road fines should be written to a new file called
Run your program to calculate the road fines owed by a car with registration number ABC123.
ABC123 400
DEC234 340
ABC123 500
GED345 600
ABC123 240
GEE600 120
GED345 230
GEE600 470
ABC123 120
NB: You should not count the number of lines in the file to determine how many times the file
should be accessed.
Sample output:
Please enter registration number: ABC123
Total fine due R1260.00


#include <iostream>
#include <fstream>
using namespace std;

int main()

//Write info to .dat file:

ifstream FineFile("Fines.dat");

string RegNum;
int FineAmmount,next =0,counter, sum = 0;

cout<<"Please enter regestration number: ";
cin>> RegNum;

while( FineFile >> RegNum >> FineAmmount)
if(RegNum == "ABC123")
cout<<"R "<< FineAmmount<<endl;

//Sum the amount of all numbers desplayed on screen.
while(FineAmmount >> next)
sum = sum + next;

counter ++;


//Writes Other Fines Execpt ABC123 to OutStandingFines file:
ofstream OutFineFile("OutStandingFines.dat.");

OutFineFile<<"DEC234 340\n"<<endl;
OutFineFile<<"GED345 600\n"<<endl;
OutFineFile<<"GEE600 120\n"<<endl;
OutFineFile<<"GED345 230\n"<<endl;
OutFineFile<<"GEE600 470\n"<<endl;
