0 likes1,389 views
This document discusses different types of statements and expressions in C# programming including selection, iteration, jump, exception handling, checked and unchecked statements. It also covers different types of operators such as arithmetic, relational, logical, conditional, increment/decrement, and assignment operators. Finally, it discusses topics like precedence and associativity of operators, data conversions, typecasting, boxing and unboxing.

- 4. Types of Operators Arithmetic Relational Logical Conditional Increment and Decrement Assignment
- 5. Arithmetic Operators are binary operators.
- 7. Logical Operators Boolean Logical Operators Bitwise Logical Operators
- 8. Bitwise Logical Operators Boolean Logical Operators http://pastebin.com/BuXr5Zxq AND
- 9. Conditional Operators AND (&&) evaluates the second expression only if the first one return true. https://gist.github.com/2318365 OR (||) evaluates the second expression only if the first one return false. https://gist.github.com/2318398
- 10. Increment and Decrement Operators
- 13. Data Conversions
- 14. Typecasting
- 15. Implicit typecasting (Coercion) refers to an automatic conversion of data type done when the destination data types belong to the same hierarchy and the destination data type must hold a larger range of values than the source data type https://gist.github.com/2318445
- 17. Explicit typecasting refers to changing a data type of higher precision into a data type of lower precision. the destination data type hold a smaller range of values than the source data type <tager data type> <variable name> = (target data type) <source data type>; https://gist.github.com/2318452
- 18. Explicit typecasting using built-in method System.Convert class Convert.ToChar(float) ToString() method https://gist.github.com/2318468
- 19. Boxing converting a value type to its reference type.
- 20. Unboxing converting a reference type to a value type
