Linked List

[chris23balln]

I am struggling with how to build a linked list. My program is a menu driven program with 6 options. The first option is to add a file. The user is prompted to enter name, id number, hours worked, and pay rate. This data is then written to a text file. All of that is good. However the 2nd option to the menu is to display a record which is where im lost. I the program is supposed to read the data from the text file into a linked list. From there the user is prompted to type in a last name and then it will search for a record based on that last name. This is where im stuck. I got the text file written, but how do I write that text file to a linked list? I think I understand how to search, but taking the data from the text and putting it into a linked list is where im lost. Any help would be appreciated. I posted my code for the text file below

void Menu(int MenuSelection, bool valid, string &EmployeeName, string &FirstName, string &LastName, int &EmployeeNumber, double &Hours, double &PayRate, char &UnionCode){
	cout << "Payroll Maintenance Program" << endl;
	cout << "         Main Menu" << endl;
	cout << endl;
	cout << "     1. Add a Record" << endl;
	cout << "     2. Display a Record" << endl;
	cout << "     3. Display the File" << endl;
	cout << "     4. Modify a Record" << endl;
	cout << "     5. Delete a Record" << endl;
	cout << "     6. Exit Program" << endl;
	cout << endl;
	cout << "  Enter your selection (1-6)-> ";
	cin >> MenuSelection;
	cout << endl;

	while (!valid){//verifies only menu numbers 1-6 are typed in
		if (MenuSelection < 7 && MenuSelection >0){
			valid = true;
		}
		else {
			cout << "Invalid Input, Please Enter a Number 1-6 Only ";
			cin.clear();
			cin.ignore(numeric_limits<streamsize>::max(), '\n');
			cin >> MenuSelection;
			cout << endl;
		}
	}

	if (MenuSelection == 1){
		GetInput(EmployeeName, FirstName, LastName, EmployeeNumber, Hours, PayRate, UnionCode);
		Menu(MenuSelection, valid, EmployeeName, FirstName, LastName, EmployeeNumber, Hours, PayRate, UnionCode);
	}

	if (MenuSelection == 2){
		cout << "Display Record" << endl;
	}
	if (MenuSelection == 3){
		cout << "Display File" << endl;
	}
	if (MenuSelection == 4){
		cout << "Modify" << endl;
	}
	if (MenuSelection == 5){
		cout << "Delete" << endl;
	}
	if (MenuSelection == 6){
		cout << "Exit" << endl;
	}
}

void GetInput(string &EmployeeName, string &FirstName, string &LastName, int &EmployeeNumber, double &Hours, double &PayRate, char &UnionCode){
	
	
	cout << "Enter Employee's First and Last Name: ";
	cin >> FirstName;
	cin >> LastName;
	cout << endl;
	EmployeeName = LastName + ", " + FirstName;
	cout << "3 Digit Employee #: ";
	cin >> EmployeeNumber;
	cout << endl;
	cout << "Hours Worked: ";
	cin >> Hours;

	while (Hours > 60){  //Hour verification, must be between 0.0 - 60.0 
		cout << endl;
		cout << "Hours must be between 0.0 and 60.0" << endl;
		cout << "Please Enter Hours Again: ";
		cin >> Hours;
		cout << endl;
	}

	cout << "Pay Rate: $";
	cin >> PayRate;

	while (PayRate < 7.50 || PayRate > 45.00){  //Pay Rate verification, must be between $7.50 and $45.00
		cout << endl;
		cout << "Pay rate must be between $7.50 and $45.00" << endl;
		cout << "Please Enter Pay Rate Again: $";
		cin >> PayRate;
		cout << endl;
	}

	cout << "Union Code(A,B,C): ";
	cin >> UnionCode;

	while (UnionCode != 'A' && UnionCode != 'B' && UnionCode != 'C'){ //Union Code verification, must be A, B, or C
		cout << endl;
		cout << "Union Code can only be A, B, or C" << endl;
		cout << "Please Enter Union Code Again: ";
		cin >> UnionCode;
		cout << endl;
	}
	cout << endl;

	ofstream myfile("Employee_Data.txt", fstream::app);
	myfile << "Name: " << EmployeeName << endl;
	myfile << "Employee Number: " << EmployeeNumber << endl;
	myfile << "Union Code: " << UnionCode << endl;
	myfile.precision(2);
	myfile.setf(ios::fixed);
	myfile.setf(ios::showpoint);
	myfile << "Hours: " << Hours << endl;
	myfile << "Rate: $" << PayRate << endl;
	myfile.close();

	cout << "Record Has Been Added" << endl;
	cout << endl;
}

It sounds like you need to create a struct in your linked list to hold your data.

After you implement the above list for your data struct, then you would need to modify your code to accept your pre-formatted input from the data in your text file.

See the links below for other examples .
