Can a loop be used to collect multiple vairables? - c++

Question

I want to promt for a string variable (name of item) and then promt for a double variable (cost). I want this to be done 5 times so each time it loops the vales are stored as a different pair of variable.
need to have user input an item and then its price so i can calc a bill.
not sure if I can crate a loop for this or i need to keep a running count somehow
int main()
{
int i;
string Item_1,Item_2,Item_3,Item_4,Item_5;
double Price_1,Price_2,Price_3,Price_4,Price_5 ;
while (i<6)
{
cout<<"Please enter item"<<endl;
cin>> Item_1>>Item_2>>Item_3>>Item_4>>Item_5>>endl;
cout<<"Please enter cost of " >> Item_1>>Item_2>>Item_3>>Item_4>>Item_5;
cin>>Price_1>>Price_2>>Price_3>>Price_4>>Price_5;
i=i++
}
return 0;
}
Code doesn't compile but i expect it to ask for my in put for the 5 variables 5 times

Answer 1

Here is a solution with arrays and a for loop.
You can try it in CPP Shell.
#include <iostream>
#include <string>
using namespace std;
int main()
{
string Item[5];
double Price[5] ;
for(int i = 0; i < 5; i++)
{
cout<<"Please enter item"<<endl;
cin>> Item[i];
cout<<"Please enter cost of " << Item[i] << ":" << endl;
cin>>Price[i];
}
cout << "Items: ";
for(int i = 0; i < 5; i++)
{
cout << Item[i] << " ";
}
cout << endl << "Prices: ";
for(int i = 0; i < 5; i++)
{
cout << Price[i] << " ";
}
return 0;
}

Your code doesn't compile for many reasons!
Of course you can use a loop for your purpose. Consider the following code, which is not really good, but does the job:
#include <string>
#include <iostream>
using namespace std;
int main()
{
int i = 1;
string Item[5];
double Price[5];
while (i<6)
{
cout<<"Please enter item "<< i << ": ";
cin>>Item[i-1];
cout<<endl;
cout <<"Please enter cost of "<< Item[i-1] << ": ";
cin >> Price[i-1];
i++;
};
i = 1;
while (i<6)
{
cout << "Item " << i << ": " << Item[i-1] << ", Price: " << Price[i-1] << endl;
i++;
};
return 0;
}
