Thread: 3 Error messages?

Hey everyone. I have this program due for an assignment tomorrow and I have 3 error messages in it. I have no clue where I went wrong. Can someone please help me? I know it can't be anything major, I just need some help please.

Here are the errors:

1>c:\users\user\documents\visual studio 2008\projects\emissions\emissions\emissions.cpp(36 ) : error C2144: syntax error : 'int' should be preceded by ')'
1>c:\users\user\documents\visual studio 2008\projects\emissions\emissions\emissions.cpp(36 ) : error C2660: 'permittedEmissions' : function does not take 0 arguments
1>c:\users\user\documents\visual studio 2008\projects\emissions\emissions\emissions.cpp(36 ) : error C2059: syntax error : ')'


Here is my program:

Code:

#include<iostream>
using namespace std;

void displayMenu();
double permittedEmissions(int, double);

int main(){
	int type;
	double grams;
	double odometer;
	const double CUT_OFF = 50000;
	const double CO_L = 3.4;
	const double CO_G = 4.2;
	const double HC_L = 0.31;
	const double HC_G = 0.39;
	const double NO_L = 0.4;
	const double NO_G = 0.5;
	const double NMHC_L = 0.25;
	const double NMHC_G = 0.31;
	double permitted;

	displayMenu();

	cout << "Enter pollutant number>> " << endl;
	cin >> type;
	cout << "Enter number of grams emitted per mile>> " << endl;
	cin >> grams;
	cout << "Enter odometer reading>> " << endl;
	cin >> odometer;

	permittedEmissions(int type, double odometer);

	return 0;
}

void displayMenu(){
	cout << "           Menu" << endl;
	cout << "(1) Carbon monoxide" << endl;
	cout << "(2) Hydrocarbons" << endl;
	cout << "(3) Nitrogen oxides" << endl;
	cout << "(4) Nonmethane hydrocarbons" << endl;
}

double permittedEmissions(int type, double odometer){
	double permittedLevel;

	switch (type){
		case 1: if (odometer <= 50000){
					permittedLevel = 3.4;
				}
				else{
					permittedLevel = 4.2;
				}
				break;
		case 2: if (odometer <= 50000){
					permittedLevel = 0.31;
				}
				else{
					permittedLevel = 0.39;
				}
				break;
		case 3: if (odometer <= 50000){
					permittedLevel = 0.4;
				}
				else{
					permittedLevel = 0.5;
				}
				break;
		case 4: if (odometer <= 50000){
					permittedLevel = 0.25;
				}
				else{
					permittedLevel = 0.31;
				}
				break;
		default: cout << "Invalid Choice" << endl;
	}

	return permittedLevel;
}

Thank you in advance for any and all help! (:

Thank yall so much. I knew my problem wasn't that big.
