The inverse Polish expression is also called the suffix expression. In the usual expression, the two-dollar operator is always placed between the two operands associated with it, and this notation is also known as infix notation. Polish logic

When interpreting complex declarators, square brackets and parentheses (that is, the modifier to the right of the identifier) take precedence over the asterisk (that is, the modifier to the left of the identifier). Brackets and parentheses have the

* * Object Basics * *1. What is an objectAn object is an unordered set of primitive data types, and this sequence is stored as a key-value pair. Each item in the sequence is called a property (called by the function), and each property name must be

PS : Const object can only be called Const Function!! Non- const objects casually!! Member pointers are applied only to non- static members of the class. The static class member is not part of any object, so no special syntax is required to point to

The operator precedence specifies how tightly the two expressions are bound. For example, the result of an expression 1 + 5 * 3 is 16 instead of 18 because multiplication sign ("*") has a higher precedence than a plus sign ("+"). You can use
