How the Monocular and binocular operators and the three-mesh operator

1, monocular operator:

The monocular operator is an operator, called a unary operator, that requires a variable to be an operation, with a logical non-operator:!, bitwise negation Operator: ~, self-reducing operator: ++,–.
Logical non-operator "!", bitwise negation operator "~", self-decrement operator "++,–", minus sign operator "-", type conversion operator (type), pointer operator and address operator "* and &", length operator "sizeof"

2, binocular operator:

The binocular operator is an operation on two variables
The elementary operator subscript operator "[]", the component operator points to the struct member operator "->", and the struct body member operator.
Arithmetic operators
Multiplication operator "*", Division Operator "/", remainder operator "%", addition operator "+", subtraction operator "-"
Relational operators
equals operator "= =", not equal to operator "!=", relational operator "< > <= >="
logical operators
Logical AND Operator "&&", Logical OR operator "| | ", logical non-operator." 】
Bitwise operators
Bitwise AND Operator "&", bitwise XOR or operator "^", bitwise OR operator "|", left move Operator "<<", Right move operator ">>"
Assignment operator
Assignment Operator "= + = = *=/=%= >>= <<= &= |= ^="
Comma operator
Comma operator ","

3, three-mesh operator:

operation of three variables;

The three-mesh operator operates on three variables and refers to an important part of the computer C language. The conditional operator is the only operator with 3 operands, so it is sometimes called a ternary operator. In general, the combination of the three-mesh operator is right-bound.
For conditional expression B? X:y, first calculate the condition B and then make a judgment. If the value of B is true, the value of x is computed and the value of x is computed, otherwise, the value of y is calculated, and the result is the value of Y. A conditional expression will never compute both X and Y. The conditional operators are right-bound, that is, grouped from right to left. For example, a? B:c? D:e will press a? B: (c. d:e) implementation. [1]
< expression 1>? < expression 2>: < expression 3>; “?” The meaning of an operator is to first evaluate the value of expression 1, and if true, execute Expression 2 and return the result of expression 2; If the value of expression 1 is false, execute the expression 3 and return the result of expression 3.
Can be understood as a condition? Result 1: The result 2 inside. The number is a format requirement. It can also be understood that the condition is not set up as a result of 1 otherwise 2.
Note: In the C language, the type of result 1 and result 2 must be the same.

int a = 1, b = 2, Z, c = 3;

Z = a > B? A: (b > C. b:c);

cout << "z:" << z << endl;
The result of this output is: Z:3
