try
{
       bool numericname=false;
       std::cout <<"\n\nEnter the Name of Customer: ";
       std::getline(cin,Name);
       std::cout<<"\nEnter the Number of Customer: ";
       std::cin>>Number;
       std::string::iterator i=Name.begin();
       while(i!=Name.end())
       {
         if(isdigit(*i))
         {
                  numericname=true;
         }
         i++;
       }
if(numericname)
{
    throw "Name cannot be numeric.";
}
} catch(string message)
{
    cout<<"\nError Found: "<< message <<"\n\n";
}

Why am I getting unhandled exception error ? Even after I have added the catch block to catch thrown string messages?
