5- Variables in C++

A variable is a name which is associated with a value that can be changed. For example when I write int num=20; here variable name is num which is associated with value 20, int is a data type that represents that this variable can hold integer values. We will cover the data types in the next tutorial. In this tutorial, we will discuss about variables.

4- Comments in C++

Program comments are explanatory statements that you can include in the C++ code. These comments help anyone reading the source code. All programming languages allow for some form of comments.
C++ supports single-line and multi-line comments. All characters available inside any comment are ignored by C++ compiler.

Lecture 10 (Complex amalgam restorations)

Complex posterior restorations are indicated when tooth structure is missing due to cusp fracture, severe caries lesion development (two or more tooth surfaces are missing), and more retention and resistance forms are needed, or replacement of existing restorative material is necessary. To compensate the lost tooth structure, may be moderate, severe or total, one or more than one retentive device is utilized. The routinely used retentive devices are: i. Slots. ii. Locks. iii. Coves. iv. Cusp Coverage Complex Amalgams. v. Crown lengthening. vi. Pins. vii. Amalgam pin. viii.
