I'm an absolute beginner and can't figure out why this program doesn't work.

Question

I started going through the c++ primer 5th edition. It says to right this program.

#include <iostream>
using namespace std;

int main()
{
std::cout << "Input two numbers." << endl;
int v1=0, v2=0;
std::cin >> v1 >> v2 >> std::endl;
std::cout << "The product of the two numbers is: " << v1*v2 << endl;
return 0;
}

Everytime I input this into the "C4 droid" app on my android it says there is a problem.

Answer 1

Change the 8th line to:
std::cin >> v1 >> v2;
For why it caused a compilation error, look here: http://www.enseignement.polytechnique.fr/informatique/INF478/docs/Cpp/en/cpp/io/manip/endl.html

Answer 2

Try changing
std::cin >> v1>>v2>>std::endl
into
std::cin >> v1>>v2

Answer 3

problem solved. thank you.
