I can't figure out what I'm missing

[boots12]

Hi guys, so I'm working on this simply lab and everything seems to work fine when I build the solution. The problem is that when I select "start with out debugging" the questions come out all at once.

#include<iostream>
#include<iomanip>



//////////////////
// Add any other libraries you need to include
//////////////////


using namespace std;

int main()
{
// The variables you will use for this program.
// You may not use any other variables or change the type
// of these variables
int price; // The price for the quantity specified by the grocery store
int quantity; // The quantity specified by the grocery store
int amount; // The amount of the product that you wish to purchase
double cost; // The cost for the number of the product that you purchase

// Ask the user to enter the price per quantity and the amount
// she would like to purchase

cout << "What is the given price? " << endl;
cin >> price;


cout << "For what quantity? " << endl;
cin >> quantity;


cout <<"What amount do you wish to purchase?" << endl;
cin>> amount;

// Calculate the cost for the amount the user would like to purchase

cost = (price/quantity)*amount;

cout << "The cost will be:" << cost << endl;

// Without using output formatting, print the result


// Change the output format so that the cost is always printed in the
// standard dollar and cents format with two digits after the decimal point

cout<< setprecision(2);
cout<< fixed;
cout << "In standard money format:" << cost << endl;




system("pause");

return 0;
}


I can't seem to figure out what I might be missing. Any help is greatly appreciated.

When I run your code, it waits for me to enter value before going on to the next question. Here is a sample run.

What is the given price? 
3
For what quantity? 
4
What amount do you wish to purchase?
5
The cost will be:0
In standard money format:0.00

If you get different behaviour, I suspect that what you're running is not actually the code above or there's something wrong with your input mechanism.

You're going to have a problem with this line:
cost = (price/quantity)*amount;

price and quantity are int values, and an int divided by an int will give you another int. If price is less than quantity, then price/quantity will come out as zero. Convert them to double or float before doing this calculation.

Ok I had to convert all the variables to double for it to work.

Thank you for your helpful tip!

Just out of curiosity, why do you ask for a price and then 2 quantities?

cout << "What is the given price? " << endl;
cin >> price;

cout << "For what quantity? " << endl;
cin >> quantity;

cout <<"What amount do you wish to purchase?" << endl;
cin>> amount;

and then do

// Calculate the cost for the amount the user would like to purchase

cost = (price/quantity)*amount;

I'm not sure I understand why your dividing the price by a quantity and then multiplying it by another quantity.
I'm probably over looking something but just seems a little off to me.

PS you didn't have to convert all your int's to doubles, price and cost probably, but you could have used the static_cast to temporarily convert your int's to doubles for your calculations.

@torind2000:
For what given price means the price is for how many units of the object.
For example:
Given Price is 150.
Quantity is 10.
That means, the price 150 is for 10 objects.

I am sure you can figure out the rest!
