An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. C++ is rich in built-in operators and provide the following types of operators −
• Arithmetic Operators
• Relational Operators
• Logical Operators
• Bitwise Operators
• Assignment Operators
• Misc Operators
This chapter will examine the arithmetic, relational, logical, bitwise, assignment and other operators one by one.
Alloy is a union of two or more metals. Amalgam: Amalgam is an alloy of mercury with any other metal. Dental Amalgam: Dental amalgam is an alloy of mercury with silver, tin, and varying amounts of copper, zinc and other minor constituents. Dental Amalgam Alloys: Dental amalgam alloys are silver tin alloys with varying amounts of copper, zinc and other metals.................
Constants refer to fixed values that the program may not alter and they are called literals.
Constants can be of any of the basic data types and can be divided into Integer Numerals, Floating-Point Numerals, Characters, Strings and Boolean Values.
Again, constants are treated just like regular variables except that their values cannot be modified after their definition.
A scope is a region of the program and broadly speaking there are three places, where variables can be declared −
• Inside a function or a block which is called local variables,
• In the definition of function parameters which is called formal parameters.
• Outside of all functions which is called global variables.
We will learn what is a function and it's parameter in subsequent chapters. Here let us explain what are local and global variables.

Esthetic dentistry has shown much advancement in materials and technology since the last century. Materials which have been used for esthetic restorations are silicate cement, glass ionomer, acrylic resins, composites and fused porcelain. R Bowen, in 1962 developed a polymeric dental restorative material reinforced with silica particles used as fillers. These materials were called ‘composites’. Nowadays, composite resins are considered as an economical and esthetic alternative to other direct and indirect restorative materials...........
