SOMEONE PLEASE HELP ME!!!:D

[budski52]

this is the program i currently have however it doesnt work and im not sure how to get it to work! many thanks :)

#include <iostream> //for cin >> and cout <<
#include <cassert> //for assert
#include <iomanip> //for endl
#include <Windows.h>

using namespace std;

void processAPrice();
int getPriceInPounds();
int convertPriceIntoEuros(int pounds);

int calculateSum(int euros);
void produceFinalData(int sum, int numberOfPrices);

int main()
{
char answer('Y');
int numberOfPrices(0);

while ((answer == 'Y') || (answer == 'y'))
{
processAPrice();
numberOfPrices++;
cout << "Continue? (Y/N)";
cin >> answer;
}

if (numberOfPrices > 0)
//produceFinalData(sum, numberOfPrices);
produceFinalData();

system("PAUSE"); //hold the screen until a key is pressed
return(0);
}


void processAPrice() //processing the given price
{
int pounds = getPriceInPounds();
int euros = convertPriceIntoEuros(pounds);
calculateSum(euros);
}

int getPriceInPounds(int priceInPounds) // get the value
{
cout << "Enter a price (in Pounds): /234";
cin >> priceInPounds;
return priceInPounds;
}


int convertPriceIntoEuros(int priceInPounds) // convert price into euros
{
const int conversionRate(0.82);
return priceInPounds / conversionRate;
}

void showPriceInEuros(int pounds, int euros)
{

SetConsoleOutputCP(1252);
cout << "The Euro value of /234" << pounds << "is: \u20AC" << euros;

}


int calculateSum(int euros) // Calculate the sum
{
int sumInEuros;
sumInEuros = (sumInEuros + euros);
return sumInEuros;
}

void produceFinalData(int sum, int numberOfPrices) // Final Output (answer)
{
SetConsoleOutputCP(1252);
cout << "The total sum is: \u20AC" << sum;
cout << "The average is: \u20AC" << (sum / numberOfPrices);

}

What do you want to do? Why doesn't it work? It doesn't compile, crashes or something else? Please use code tag: http://www.cplusplus.com/articles/jEywvCM9/
Don't use system(), it's BAD. You can use std::cin.get() instead. Your program takes input, so you've got to use it two times before return 0;
EDIT:
You use your function "produceFinalData" with no arguments in main(), there is no such overload

[budski52]

there is a red line inder produceFinalData(); and it says too few arguments in function call. im not sure how i should fix this


int main()
{
char answer('Y');
int numberOfPrices(0);

while ((answer == 'Y') || (answer == 'y'))
{
processAPrice();
numberOfPrices++;
cout << "Continue? (Y/N)";
cin >> answer;
}

if (numberOfPrices > 0)
//produceFinalData(sum, numberOfPrices);
produceFinalData();

system("PAUSE"); //hold the screen until a key is pressed
return(0);
}

[TheHardew]

You've got to give arguments to function call, e.g.

int sum = 78, nrOfPrices = 98;
produceFinalData(sum, nrOfPrices);

EDIT:
also, your calculateSum function uses sumInEuros variable without initializing it:

int sumInEuros;
sumInEuros = (sumInEuros + euros);

im a complete noob at this. c++ is a brand new language to me so could you show me how to do it please?
many thanks :)

[TheHardew]

Maybe get some book, C++ is a HUGE language. There are also internet tutorials. Firstly tell me what do you want to do, 'cuz if you don't know it, I won't know it either.

[budski52]

okay, basically i want the program to convert from pounds to euros

[TheHardew]

Voilà!

#include <iostream> //for I/O

using namespace std;

const double PoundsToEuros = 1.34; // double for floating point numbers

int main(){
	char answear;
	unsigned input; // unsigned - only non-negative numbers (0 and up)

	do{
		cout << "Input price in pounds(without pences): ";
		cin >> input;
		cout << input << " pounds is equal to " << input * PoundsToEuros << " euros\n";
		cout << "Do you want to continue (y/n): ";
		cin >> answear;
		cout << std::endl;
	} while (answear == 'Y' || answear == 'y');

	cout << "Bye! Press Enter...";
	cin.get(); // one is skipped due to previous input
	cin.get();
	return(0);
}

thanks for your help. its for a college project so i have to use this format, i know, its stupid haha.

#include <iostream> //for cin >> and cout <<
#include <cassert> //for assert
#include <iomanip> //for endl
#include <Windows.h>

using namespace std;

void processAPrice();
int getPriceInPounds();
int convertPriceIntoEuros(int pounds);

int calculateSum(int euros);
void produceFinalData(int sum, int numberOfPrices);

int main()
{
	char answer('Y');
	int numberOfPrices(0);

	while ((answer == 'Y') || (answer == 'y'))
	{
		processAPrice();
		numberOfPrices++;
		cout << "Continue? (Y/N)";
		cin >> answer;
	}

	if (numberOfPrices > 0)
		//produceFinalData(sum, numberOfPrices);
		produceFinalData();

	system("PAUSE"); //hold the screen until a key is pressed
	return(0);
}


void processAPrice() //processing the given price
{
	int pounds = getPriceInPounds();
	int euros = convertPriceIntoEuros(pounds);
	calculateSum(euros);
}

int getPriceInPounds(int priceInPounds) // get the value
{
	cout << "Enter a price (in Pounds): /234";
	cin >> priceInPounds;
	return priceInPounds;
}


int convertPriceIntoEuros(int priceInPounds) // convert price into euros
{
	const int conversionRate(0.82);
	return priceInPounds / conversionRate;
}

void showPriceInEuros(int pounds, int euros)
{

	SetConsoleOutputCP(1252);
	cout << "The Euro value of /234" << pounds << "is: \u20AC" << euros;

}


int calculateSum(int euros) // Calculate the sum
{
	int sumInEuros;
	sumInEuros = (sumInEuros + euros);
	return sumInEuros;
}

void produceFinalData(int sum, int numberOfPrices) // Final Output (answer)
{
	SetConsoleOutputCP(1252);
	cout << "The total sum is: \u20AC" << sum;
	cout << "The average is: \u20AC" << (sum / numberOfPrices);

}

Where is this code from? Is this from your teacher, from book, it's your own or it's from somewhere else? I showed you how to do it, you can change this code. Nobody is going to do projects for you, so you can graduate the school.

[budski52]

its my own.. i've done all of that code however i got stuck on a little bit, sorry for asking jeeeez

[TheHardew]

It will be beter if you read some tutorials, it seems you don't know the basics. This seems like a good tutorial: http://www.learncpp.com/
