My goal is to produce the sum and product to all elements but
I have a problem how to get product to all elements.
CODE
inner_product()
will not work.
CODE
#include <iostream>
#include <vector>
#include <algorithm>
#include <numeric>
using namespace std;
int main()
{
vector <double> number1, number2(1);
double x;
char answer;
cout << "Do you want enter number (y/n)?";
cin >> answer;
while (answer == 'y' || answer == 'Y')
{
cout << "Enter number:";
cin >> x;
number1.push_back(x);
cout << "Do you want enter more numbers (y/n)?"<< endl;
cin >> answer;
}
for (int i=0; i<number1.size(); i++)
{
cout <<"The numbers are:" << " " << number1[i] <<"\n";
}
cout << "\n\n";
cout << "Total is:"
<< accumulate(number1.begin(), number1.end(), 0.0000) <<"\n\n";
cout << "Product is:"
<< inner_product(number1.begin(), number1.end(), number2.begin(), 0.0000) <<"\n\n";
return 0;
}
