Unary Operators in C++

C++ includes a class of operators that act upon a single operand to produce a new value. Such operators are known as unary operators. Unary operators usually precede their single operands, through some unary operators are written after their operands. Perhaps the most common unary operation is unary minus, where a numerical constant, variable or expression is preceded by a minus sign. Note that the unary operation is distinctly different from the arithmetic operator which denotes subtraction (-) as the subtraction operator requires two operands. Example: -743 -0x7fff -0.2 -5E-8 -root1 -(x + y) -3 * (x + y)

Operators and Expressions in C++

An operator, in general, is a symbol that operates on a certain data-type. For example, the operator + is the addition operator. It can operate on integer, character and real (float and double) numbers. On the other hand, an expression is a combination of variables, constants and operators written according to the syntax of the language. Types of Operators: Arithmetic operators Unary operators Increment and Decrement operators Relational operators Logical operators Assignment operators Conditional operators
