help with for loops

[Chris2424]

Trying to get 'parallel arrays" to match up and give product, price, and have user input quantity then generate a total amount at end. Very new to C++ and having trouble getting the order and sequence down right. PLEASE HELP!!

#include <iostream>

using namespace std;

int main()
{
string PRODUCT[3] = { "Men's Golf Ballz", "Women's Golf Ballz", "Kids Golf Ballz" };

int QUANT[3];

double PRICE[3] = { 23.00, 20.00, 15.00 };

cout << "Product #1 - Men's Golf Ballz are $23.00/dozen" << endl;
cout << "Product #2 - Women's Golf Ballz are $20.00/dozen" << endl;
cout << "Product #3 - Kid's Golf Ballz are $15.00/dozen" << endl;

for (int counter = 0; counter < 3; counter++)
{
cout << "Enter quantity for Product # " << counter + 1 << ": ";
cin >> QUANT[counter];
}

for (int index = 0; index < QUANT; index++);
{
double total = int QUANT[] * double PRICE[];


}
}

Hi,
Please use code tags

here's a solution, necessary things are explained as comments
do ask if you have any doubt

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

#include <iostream> using namespace std; int main() { string PRODUCT[3] = { "Men's Golf Ballz", "Women's Golf Ballz", "Kids Golf Ballz" }; int QUANT[3]; double PRICE[3] = { 23.00, 20.00, 15.00 }; cout << "Product #1 - Men's Golf Ballz are $23.00/dozen" << endl; cout << "Product #2 - Women's Golf Ballz are $20.00/dozen" << endl; cout << "Product #3 - Kid's Golf Ballz are $15.00/dozen" << endl; double total=0;//inistialize total to zero for (int counter = 0; counter < 3; counter++) { cout << "Enter quantity for Product # " << counter + 1 << ": "; cin >> QUANT[counter]; //the whole thing can be kept inside one for loop only total = QUANT[counter] * PRICE[counter];//you dont need to redeclare data type } cout<< "Your total bill is : $"<<total; }

Product #1 - Men's Golf Ballz are $23.00/dozen Product #2 - Women's Golf Ballz are $20.00/dozen Product #3 - Kid's Golf Ballz are $15.00/dozen Enter quantity for Product # 1: 3 Enter quantity for Product # 2: 6 Enter quantity for Product # 3: 4 Your total bill is : $60

Hope it helps

    string PRODUCT[3] = { "Men's Golf Ballz", "Women's Golf Ballz", "Kids Golf Ballz" };

    int QUANT[3];

    double PRICE[3] = { 23.00, 20.00, 15.00 };

    cout << "Product #1 - Men's Golf Ballz are $23.00/dozen" << endl;
    cout << "Product #2 - Women's Golf Ballz are $20.00/dozen" << endl;
    cout << "Product #3 - Kid's Golf Ballz are $15.00/dozen" << endl;

    for (int counter = 0; counter < 3; counter++)
    {
        cout << "Enter quantity for Product # " << counter + 1 << ": ";
        cin >> QUANT[counter];

    for (int index = 0; index < QUANT; index++);
    {
        double total = int QUANT[] * double PRICE[];
    }
}

Reposting your original code for readability and line numbers

[mpark4656]

Line 23 - QUANT is an array of int type. It's missing [x] and also, why is it being compared to index in the first place? Take out semi-colon at the end.

Line 25 - QUANT and PRICE have [] but missing the index. You do not specify type in front of variables. You specify type only when you declare variables.

This is the code after I fixed your last for-loop (Only the syntax, not the logic)

    for (int index = 0; index < 3; index++ )
    {
        double total = QUANT[index] * PRICE[index];
    }

Now, what are you trying to accomplish with this for-loop? You want to print the total price, right? In order to print the total price, shouldn't you include cout?

[Chris2424]

I got the code to start working without errors, but the equation is only giving me the last "products price * quantity". It's only giving me the total end price for the "Kids golf ballz" not including the other 2 products before it.
