♣ Example4: String to Int in C++

A string is a Data Type which composes of a sequential arrangement of characters forming a Text.
Int is a Data Type which can store integer values of certain range.
Note that only those strings can be converted to an integer which is numeric, for example, "45", "2.3", etc.
In this example, multiple String to Int conversions are illustrated.
