- What is the output of this program?

#include <string>
using namespace std;
int main()
{
double Option1 = 12, Option2 = 6, Result;
char Option;
try
{
if (Option != '+' && Option != '-' && Option != '*' && Option != '/')
throw Option;
switch(Option)
{
case '+':
Result = Option1 + Option2;
break;
case '-':
Result = Option1 - Option2;
break;
case '*':
Result = Option1 * Option2;
break;
case '/':
Result = Option1 / Option2;
break;
}
cout << "\n" << Option1 << " " << Option << " "<< Option2 << " = " << Result;
}
catch (const char ch)
{
cout << ch << "Is not a valid Option...";
}
return 0;
}

double DivFunction(int num1, int num2)
{
if ( num2 == 0 )
{
throw "Division by zero condition Occurred...";
}
return (num1 / num2);
}
int main ()
{
int m = 10;
int n = 0;
double Res = 0;
try
{
Res = DivFunction(m, n);
cout << Res << endl;
}
catch (const char* msg)
{
cout << msg << endl;
}
return 0;
