Deleting account information from a file

[samofdrones]

I'm attempting to delete an account from my accounts.txt file, but I can't seem to get it to work. I'm attempting to put white spaces into the account file, but it doesn't seem to be working.

//function: delete account
void delAct(account one[]){

	int actChoice;
	ofstream fdata;
	int x = 0;
	cout << "Enter the account number you would like to delete: ";
	cin >> actChoice;

	while (!(actChoice == one[x].actNum)){
		x++;
	}
	if (actChoice == one[x].actNum){

			cout << "You have selected...\n\n";
			cout << "Account number: " << one[x].actNum;
			cout << "\n";
			cout << "Acount name: " << one[x].name;
			cout << "\n";
			cout << "Balance: " << one[x].balance;
			cout << "\n";
	 }//if
	
	fdata.open("accounts.txt");
	if (fdata.fail()){
		cerr << "Error opening file" << endl;
		system("PAUSE");
		exit(1);
		}//if

		fdata << " ";
		fdata << " "; 
		fdata << " ";

		fdata.close();
}//void
