Question

Write, compile, and run a C++ program that declares three one-dimensional arrays
named price, quantity, and amount. Each array should be declared in main() and be
capable of holding 10 double-precision numbers. The numbers to store in price are 10.62,
14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in quantity
are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to
a function named extend(), which should calculate elements in the amount array as the
product of the corresponding elements in the price and quantity arrays (for example,
amount[1]ƒ= price[1]ƒ*ƒquantity[1]). After extend() has passed values to the amount
array, the values in the array should be displayed from within main().

Answer 1

#include <iostream>

using namespace std;

void extend(double price[10], double quantity[10], double* amount)
{
for (int i(0); i < 10; i++)
{
amount[i] = price[i] * quantity[i];
cout << "amount[" << i + 1 << "] = " << amount[i] << endl;
}
system("pause >> void");
}

int main()
{
double amount[10];
double price[10] = {10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, 3.98},
quantity[10] = { 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, 4.8 };
extend(price, quantity, amount);
}
