//c + + Operators 
//Operators specify an evaluation to be performed on one of the following: 
//One operand (unary operator) 
//Two operands (binary operator) 
//Three operands (ternary operator) 
//The C + + language includes all C operators and adds several new operators. 
//Table 1.1 lists the operators available in Microsoft c + +. 
//Operators follow a strict precedence which defines the evaluation order of 
//expressions containing these operators. The operators associate with either the 
//expression on their left or the expression on their right. This is called 
//"associativity." Operators in the same group have equal precedence and are 
//evaluated left to right in an expression unless explicitly forced by a pair of 
//parentheses, (). 
//Table 1.1 shows the precedence and associativity of c + + operators 
//(from highest to lowest precedence). 
//
//Table 1.1 c + + Operator Precedence and Associativity 
//The highest precedence level is at The top of The table.
