Thread: Cannot convert parameter to struct type.

I am trying to make a automated menu. It shows there are no syntax errors but when compiled it says cannot convert choice from type into to menuItemType. I am not sure what I did wrong. Here is the code

Code:

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




using namespace std;


struct menuItemType
{
    string menuItem;
    double menuPrice;
    
};


const int NUMBER_OF_ROWS = 8;
const int NUMBER_OF_COLUMNS = 2;






double showMenu(menuItemType menuList[NUMBER_OF_ROWS]);
void getData(menuItemType menuList[NUMBER_OF_ROWS]);
double printCheck(menuItemType menuList[NUMBER_OF_ROWS]);


int main()
{
    
    menuItemType menuList[NUMBER_OF_ROWS];
    getData(menuList);
    showMenu(menuList);
    
    
    
}


void getData(menuItemType menuList[NUMBER_OF_ROWS])
{
    
    ifstream inFile;
    inFile.open("C:\\Users\\Dylan\\Documents\\InfileTravischapter9Page629.txt");
    
    for (int i = 0; i < 8; i++)
    {
        inFile >> menuList[i].menuItem
               >> menuList[i].menuPrice;
    }       
}


double showMenu(menuItemType menuList[NUMBER_OF_ROWS])
{
    
    getData(menuList);
    int choice;
    bool selectAnother;
    for(int i=0; i < 8; i++)
    { 
    cout << menuList->menuPrice << endl;
    }
    cout << "What would you like to eat, you can have up to one of each item on the menu" << endl;
    cout << "Press the following keys to select your items" << endl;
    cout << "1 = Plain\n2 = Bacon and Egg\n 3 = Muffin\n 4 = French Toast\n 5 = Fruit Basket \n 6 = Cereal \n 7 = Coffee \n 8 = Tea" << endl;
    cin >> choice;
    cout << "Would you like to select another item? Enter yes or no" << endl;
    cin >> selectAnother;
    
    while(selectAnother == true)
    {
    cout << "What would you like to eat, you can have up to one of each item on the menu" << endl;
    cout << "Press the following keys to select your items" << endl;
    cout << "1 = Plain\n2 = Bacon and Egg\n 3 = Muffin\n 4 = French Toast\n 5 = Fruit Basket \n 6 = Cereal \n 7 = Coffee \n 8 = Tea" << endl;
    cin >> choice;
    cout << "Would you like to select another item? Enter yes or no" << endl;
    cin >> selectAnother;
    }
    
    printCheck(choice);
    
    


    return 0;
}


double printCheck(int choice)
{
    double bill;
    double price;
    double check;
    
    
    if(choice == 1)
        price = 1.45;
    if(choice == 2)
        price = 2.45;
    if(choice == 3)
        price = .99;
    if(choice == 4)
       price = 1.99;
    if(choice == 5)
        price = 2.49;
    if(choice == 6)
        price = .69;
    if (choice == 7)
        price = .50;
    if(choice == 8)
        price = .75;




    bill = bill + price;
    check = bill * .05 + bill;


    cout << "Your check is $" << check << endl;
    
}

Whoa, whoa, whoa; hold the horses! Somebody used the words argument and parameter correctly!

I understand now. I had a variable in my function prototype that i wasn't even using. Okay i got it fixed but now when i run it this happens. My menu is messed up. I tryed to format my menu to pop up like this with a text file but instead of a menu popping up it says the bottom is right. but the top should display a item then the price not a bunch of numbers. then when I select yes to enter another choice it infinite loops. so i will have to fix that to.

What would you like to eat, you can have up to one of each item on the menu
Press the following keys to select your items
1 = Plain
2 = Bacon and Egg
3 = Muffin
4 = French Toast
5 = Fruit Basket
6 = Cereal
7 = Coffee
8 = Tea

I am trying to output the whole menu but now im getting 1 error C2676: binary '[' : 'menuItemType' does not define this operator or a conversion to a type acceptable to the predefined operator
here is the method im trying

Code:

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




using namespace std;


struct menuItemType
{
	string menuItem;
	double menuPrice;
	
};


const int NUMBER_OF_ROWS = 8;
const int NUMBER_OF_COLUMNS = 2;






double showMenu(menuItemType menuList[NUMBER_OF_ROWS]);
void getData(menuItemType menuList[NUMBER_OF_ROWS]);
double printCheck(double choice);


int main()
{
	
	menuItemType menuList[NUMBER_OF_ROWS];
	getData(menuList);
	showMenu(menuList);
	
	
	
}


void getData(menuItemType menuList[NUMBER_OF_ROWS])
{
	
	ifstream inFile;
	inFile.open("C:\\Users\\Dylan\\Documents\\InfileTravischapter9Page629.txt");
	
	for (int i = 0; i < 8; i++)
	{
		for(int j=0; j<2; j++) //This loops on the columns
		{
		inFile >> menuList[i].menuItem
			   >> menuList[j].menuPrice;
	
		}
	}
}


double showMenu(menuItemType menuList[NUMBER_OF_ROWS])
{
	
	getData(menuList);
	double choice;
	bool selectAnother;
	for(int i=0; i<8; i++)   
	{
		for(int j=0; j<2; j++) 
		{
			cout << menuList[i][];
		}
		cout << endl;
	}

"cout << menuList[i][]" -- even if you had something in the last set of braces, menuList is still only a one-dimensional array.

am i getting any closer? The program now runs but it dosen't output the menu right still. It just gives me a bunch of random numbers that aren't even in the .txt file.

Code:

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




using namespace std;


struct menuItemType
{
	string menuItem;
	double menuPrice;
	
};


const int NUMBER_OF_ROWS = 8;
const int NUMBER_OF_COLUMNS = 2;






double showMenu(menuItemType menuList[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS]);
void getData(menuItemType menuList[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS]);
double printCheck(double choice);


int main()
{
	
	menuItemType menuList[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS];
	getData(menuList);
	showMenu(menuList);
	
	
	
}


void getData(menuItemType menuList[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS])
{
     
    ifstream inFile;
    inFile.open("C:\\Users\\Dylan\\Documents\\InfileTravischapter9Page629.txt");
     
    for (int i = 0; i < 8; i++)
    {
        for(int j=0; j<2; j++) //This loops on the columns
        {
        inFile >> menuList[i][j].menuItem
               >> menuList[i][j].menuPrice;
     
        }
    }
}
 


double showMenu(menuItemType menuList[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS])
{
     
    getData(menuList);
    double choice;
    bool selectAnother;
    for(int i=0; i<8; i++)   
    {
        for(int j=0; j<2; j++) 
        {
            cout << menuList[i][j].menuItem;
			cout << menuList[i][j].menuPrice;
        }
      
    }
