Problem with Mixing cin and cin.get

1. Mixing cin with cin.get can cause annoying and hard-to-find problems.
   For example, consider the following program:
   
   // Illustrate problems when cin is used together with get.
   // Suppose the user types as input:
   // 12 and press enter and a c and press enter.
   #include <iostream>
   using namespace std;
   
   int main( )
   {
       int num;
       char ch;
   
       cout << "Enter an integer: ";
       cin >> num;
       cout << "You entered the integer: " << num << endl;
       cout << "Enter a character: ";
       //cin >> ch;
       cin.ignore(10,'\n');       // need this line to work
       cin.get(ch);
       cout << "You entered the character: " << ch << endl;
   
       return 0;
   }
