In addition to the operators like arithmetic operators, relational operators, logical operators, the conditional operator and assignment operators that most of the languages support, C++ provides various new operators that are given in Table
The Precedence Operator Specifies in a Expression Which Operator will Execute first, when there are Many Operators in an Expression. So that the Operator Precedence defines the Sequence or the Way for Performing the Operations of the Operators.
All the Above Operators are Called as Binary Operators because they takes two Operands for Performing an Operation. But the Increment and decrement operators are called as Unary because they takes only one operand For Performing an Operation This Operator Contains ++ for Increment and -- for Decrement.
An operator is a symbol which helps the user to command the computer to do a certain mathematical or logical manipulations. Operators are used in C++ language program to operate on data and variables. C++ has a rich set of operators which can be classified as
A global variable is one whose value can be used anywhere in the program. Its value can be used in the Main() function and all other functions in the program. However, a local variable is one whose value is local to the function i.e. its value can be used in that particular function only where it is declared. A global variable is defined before the Main() function. Same name can be given to local and global variables. For example in the following program segment
