Bugged shit.

#include <iostream>

using namespace std;

int a; // Globally copying it here because I don't feel like cluttering int main up even more.
int b; //
int c; //

int dividemultiply (int a, int b=2, int c=4) //
{
  int r;
  r=a/b*c;
  return (r);
}

int main ()
{
  cout << "Input a number.\n";
  cin >> a; //It always crashes after you put a number in... No idea why.
  cout << dividemultiply (a,14,c); //A is supposed to be defined by the line above. C is supposed to be defined by line 9.
  cout << endl;
  cout << dividemultiply (a,b,2); //A is supposed to be defined by line 19. B is supposed to be defined by line 9.
  return 0;
}
