/*File:  Input01.cpp
This C++ program illustrates simple standard
input from the keyboard. 

When the type of input data matches the types 
of the variables into which the data is stored,
the program runs correctly producing the 
following screen output:

Enter three values separated by spaces
1 2 3
1 2 3
Press any key to continue

However, when the type of the input data fails 
to match the types of the variables into which
the data is stored, the program fails, as shown
in the following screen output, but doesn't give
any other indication that a failure has occurred.

Enter three values separated by spaces
1 1.5 2
1 1 -858993460
Press any key to continue
