Function returning a string literal

[LiverpoolFTW]

Ok, so its more EECS 168. I pretty much have most of this program written, the only problem i am having is getting one of my functions to return a string literal.

Here is the assignemnet:
https://wiki.ittc.ku.edu/ittc/EECS168:Homework2
(I find it much easier to just link this rather than spam this post with a huge long assignment description.)

Here is my code so far:

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

double average_standard(double stand_total, double days_worked_par);
double average_one(double one_total, double days_worked_par);
double average_two(double two_total, double days_worked_par);
double average_deluxe(double deluxe_total, double days_worked_par);
double banana_points_func(double stand_average, double one_average, double two_average, double delux_average, double wasted);
string star_rating(double points);


int main()
{

double days_worked;
double stan_choc_numb, one_topping_numb, two_topping_numb, deluxe_numb;
double stan_choc_total = 0;
double one_topping_total = 0;
double two_topping_total= 0;
double delux_total = 0;
double wasted_bans = 0;
int n;
char choice;

do
{
//User input for number of days worked
cout << "Enter the number of days the employee worked: ";
cin >> days_worked;
cout << "\nEnter the amount of each typer for each day worked.\n";

for (n = 1; n <= days_worked; n++)
{
	//Getting the number of bananas sold for each day
	cout << "Day " << n << endl;
	cout << "Standard Chocolate Covered: ";
	cin >> stan_choc_numb;
	cout << "One-Topping: ";
	cin >> one_topping_numb;
	cout << "Two-Topping: ";
	cin >> two_topping_numb;
	cout << "The Deluxe: ";
	cin >> deluxe_numb;
	//Adding the days numbers to the running total
	stan_choc_total = stan_choc_total + stan_choc_numb;
	one_topping_total = one_topping_total + one_topping_total;
	two_topping_total = two_topping_total + two_topping_numb;
	delux_total = delux_total + deluxe_numb;
}

//Getting number of wasted bananas
cout << "Enter the number of wasted bananas: ";
cin >> wasted_bans;


//Calling functions and setting them to variables
double standard_choc_average = average_standard(stan_choc_total, days_worked);
double one_topping_average = average_one(one_topping_total, days_worked);
double two_topping_average = average_two(two_topping_total, days_worked);
double delux_average = average_deluxe(delux_total, days_worked);
double banana_points = banana_points_func(standard_choc_average, one_topping_average, two_topping_average, delux_average, wasted_bans);


//Outputting results to user
cout << "\nAverage Sold Per Day:\n";
cout << "Standard Chocolate Covered: " << standard_choc_average << endl;
cout << "One-Topping: " << one_topping_average << endl;
cout << "Two-Topping: " << two_topping_average << endl;
cout << "The Delux: " << delux_average << endl << endl;
cout << "Banana Points: " << banana_points << endl << endl;

string star_rating(banana_points);

cout << "\n\nIs there another employee to calculate? (y/n): ";
cin >> choice;

}while ((choice != n) || (choice != N))

return 0;

}

double average_standard(double stand_total, double days_worked_par)
{
	double average = stand_total / days_worked_par;
	return (average);
}

double average_one(double one_total, double days_worked_par)
{
	double average = one_total / days_worked_par;
	return (average);
}


double average_two(double two_total, double days_worked_par)
{
	double average = two_total / days_worked_par;
	return (average);
}

double average_deluxe(double deluxe_total, double days_worked_par)
{
	double average = deluxe_total / days_worked_par;
	return (average);
}

double banana_points_func(double stand_average, double one_average, double two_average, double delux_average, double wasted)
{
	double point_total = ((stand_average) + (2 * one_average) + (3 * two_average) + (5 * delux_average) - (4 * wasted));
	return (point_total);
}


string star_rating(double points)
{
	if (points >= 125)
		return "This employee has earned a Five Star rating.";
	
	if else ((points >= 75) && (points < 125))
		return "This employee has earned a Four Star rating.";	

	if else ((points >= 50) && (points < 75))
		return "This employee has earned a Three Star rating.";

	if else ((points >= 25) && (points < 50))
		return "This employee has earned a Two Star rating.";
	
	if else ((points >= 10) && (points < 25))
		return "This employee has earned a One Star rating.";
	
	else
		return "This employee should be fired.";
}

The last function (string star_rating) is the one i am having issues with. I feel like once i get that working then the rest will be smooth sailing. I am not too worried about the rest of the program right now. If you see any logic errors then i will probably be able to pick those out once i get this darn thing to compile. I dont really know the syntax for the string function so that is my main concern right now. Any help is much appreciated. If you have any questions or i forgotten to mention any details, please let me know.

Thanks,

string star_rating(banana_points);

Line 73, that is not how you call a function. (Which is what I assume you are trying to do there.) Re-check your tutorial/book/whatever.

I knew that line was not going to be right. I just stuck that in there before i put my code up to show that i needed my string returned from the function to be put there. I think i could use a void function to get this final function done but i am worried that our professor wants us to return a string literal.

I cant really trouble shoot anything so far because the only error i get is in my final function.

The error i get every time is:

banana.cpp: In function ‘std::string star_rating(double)’:
banana.cpp:129: error: expected ‘(’ before ‘else’
banana.cpp:132: error: expected ‘(’ before ‘else’
banana.cpp:135: error: expected ‘(’ before ‘else’
banana.cpp:138: error: expected ‘(’ before ‘else’
banana.cpp:141: error: ‘else’ without a previous ‘if’

I have looked online and through the book for a long time before posting, but i can't find the proper syntax for this final function.

In the implementation of function string star_rating(double points)

The if else chain or ladder has the following format:

if ( condition1 )
   statement1;
else if ( condition2 )
   statement2;
else if ( condition3 )
   statement3;
 .
 .
 .

I have not looked for other possible errors.

Wow, i cant believe i did that haha..... i guess thats what i get for doing programming at 1 in the morning,

EDIT: after fixing that simple mistake, the program compiled and that allowed me to test with line 73 ad get that to work (i just set it to a string variable x and then cout << x). I had one or two logical errors that i needed to fix. Works great now. Thank you all for your help. Always useful to have fresh eyes find my stupid mistakes :)
