Part I. Basic mathematical calculation
1. How are Integer and String data types used in an application?
Integers are used to store real numbers which do not have any fractional or decimal part. They are usually used in different types of mathematical calculations. String data types can include letters, special characters, and numerals as well, but they cannot be used in Mathematical calculations. They can only be used in concatenations, and display. However, it is possible to convert a 'numeral only' string variable into an integer or double, and use this value in mathematical calculations.
