Never mind. I finally figured it out.

Well, I got the 'for' statement correct, but it still isn't printing a list of choices or adding the amounts. Should I put an 'if' statement in there? Please advise. This is due tonight.

Thanks!

Here's the most recent code that I've done.

#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>

using namespace std;

const int noOfItems = 8;

struct menuItemType
{
	string menuItem;
	double menuPrice;
};

void getData(ifstream& inFile, menuItemType mList[], int listSize);
void showMenu(menuItemType mList[], int listSize);
void printCheck(menuItemType mList[], int listSize, 
				int cList[], int cListLength);
void makeSelection(menuItemType mList[], int listSize, 
					int cList[], int& cListLength);
bool isItemSelected(int cList[], int cListLength, int itemNo);

int main()
{
	menuItemType menuList[noOfItems];
	int choiceList[noOfItems];
	int choiceListLength;
	
	ifstream inFile;

	cout << fixed << showpoint << setprecision(2);

	inFile.open("Ch12_Ex3Data.txt");

	if (!inFile)
	{
		cout << "Cannot open the input file. Program Terminates!"
			 << endl;
		return 1;
	}
	getData (inFile, menuList, noOfItems);
	showMenu(menuList, noOfItems);
	makeSelection(menuList, noOfItems, choiceList, choiceListLength);
	printCheck(menuList, noOfItems, choiceList, noOfItems);

	return 0;
}

void getData(ifstream& inFile, menuItemType mList[], int listSize)
{
	char ch;
	for (int i = 0; i < listSize; i++)
	{
		getline(inFile, mList[i].menuItem);
		inFile >> mList[i].menuPrice;
		inFile.get(ch);
	}
}

void showMenu(menuItemType mList[], int listSize)
{
	cout << "Welcome to Johnny's Restaurant" << endl;
	cout << "----Today's Menu----" << endl;

	for (int i = 0; i < listSize; i++)
		cout<<left<<setw(15)<<mList[i].menuItem<<right<<mList[i].menuPrice<<endl;
	cout<<endl;
}

void printCheck(menuItemType mList[], int listSize, 
				int cList[], int cListLength)
{
	int i;
	double salesTax;
	double amountDue = 0;
	
	cout << "Welcome to Johnny's Restaurant" << endl;

	for (i = 0; …

OK, I finally got it to print out in the tabular format, but I still can't get it to add the amounts. I've tried a few different things, but I think my for loop may be wrong. Can someone help, please?

Thanks!

OK, here's my problem. This is supposed to print out a list of menu items. You choose from the list, then print the bill. My problem is that I can't seem to get the menu items to print out in a tabular format and my printout won't add the items together. I keep getting zeros for the tax and amount due. Any help is greatly appreciated.

Thanks!

I'm writing a program that asks the user to input 3 numbers, then outputs the shape of the triangle. This is what I have so far, but it still doesn't work.

Can someone help?

Thanks!

#include <iostream>
using namespace std;

enum triangleType {scalene, isosceles, equilateral, noTriangle};

void triangleShape (int shape);

int main()
{
	float A, B, C;
	int shape;
	
	cout<<"Enter the length of three sides of a triangle"<<endl;
	cin>>A;
	cin>>B;
	cin>>C;
	triangleShape (shape);
	if (shape == equilateral)
		cout<<"The shape of the triangle is: equilateral";
	else if (shape == isosceles)
		cout<<"The shape of the triangle is: isosceles";
	else if (shape == scalene)
		cout<<"The shape of the triangle is: scalene";
	else
		cout<<"The shape of the triangle is: noTriangle";
	cout<<endl;
	return 0;
}

void triangleShape (int shape)  //my instructor said to make shape of
                                         //type triangleShape, but I'm not sure 
                                        //what that means, plz explain
{
	int A, B, C;
	int shape;

	if ((A == B)&&(B == C))
		shape = equilateral;
	else  if ((A == B)||(B == C)||(A == C))
		shape = isosceles;
	else if ((A != B)||(B != C)||(A != C))
		shape = scalene;
	else
		shape = noTriangle;
}

Thank you so much! This worked beautifully.

I'm fairly new to this stuff, so I usually ask a lot of questions if I'm not quite sure about something.

Is this what you mean?

while (max > 0.0 || max <= 10.0)

I have to write a program for homework that asks for contestant scores, then outputs the total after the lowest and highest number are deleted. This is what I have so far. I can't use a sort since we haven't covered that yet and I'm not sure exactly how to subtract the lowest and highest number without sorting. Any help is much appreciated.

Thanks!

#include <iostream>
using namespace std;

int main()
{
	int counter;
	double sum;
	double data [8];

	cout<<"Enter data: ";
	
	for (counter = 0; counter < 8; counter++)
		data[counter] = 0.0;
	for (counter = 0; counter < 8; counter++)
		cin>>data[counter];
	sum = 0;
	for (counter = 0; counter < 8; counter++)
		sum = sum + data[counter];
	cout<<endl;

	
	cout<<"Total points =  "<<sum<<endl;

	return 0;
}

I have to write code that will prompt you to input a sentence, then it will output the number of vowels in the sentence. This is what I have so far. Can someone tell me what is wrong with it?

Thanks so much!

//Input a sentence, then return number of vowels in the sentence
#include <iostream>
using namespace std;

char ch(char vowel);
char isVowel (char a, char e, char i, char o, char u);

int main ()

char sentence;
char isVowel;
int number;
{
	cout<<"Enter a sentence"<<endl;
	cin>>sentence;
	cout<<"There are "<<number<<" vowels in this sentence."<<endl;

	return 0;

}
char isVowel (char a, char e, char i, char o, char u)
{
	if (ch = 0)
		return number;
	else
		return false;
}
