Relationships, logic, conditional operators

One, Operator:
(i), relational operators: > < >= <= = = =!
1, bool a = ten > 5; The result of the relationship comparison, the type must be bool,
Must be received with a variable of type bool.
(ii), logical operators
1. && and:
Example: 10<11 && 10>9:true, 10<11 && 10<9:false

PS: and relationship: As long as there is one that is not true, then return False,
If you want to return true, then it must all be set up

2, | | Or:
Example: 10<11 | | 10<9:true, 10<9 | | 10>11:false
PS: or relationship: As long as there is a set, then return True,
If you want to return false, you must not have it all

3,! Non: Apology

(iii), conditional operators
Data Type A = comparison expression? Value: value;
For example: a = 10;
b = 15;
String a = (a > B)? "Yes": "Wrong";

Exercises
1.
Please enter your name:
Please enter gender (1/0):
My name is xxx, I am xxx.

            //receiving information entered by the userConsole.Write ("Please enter your name:"); stringName =Console.ReadLine (); Console.Write ("Please enter gender (1/0):"); intSex =Convert.ToInt32 (Console.ReadLine ()); //calculate a comparison to derive a variable            stringx = Sex = =1?"male":"female"; //Print OutputConsole.WriteLine ("My name"+ name +", I was"+ x +"the. "); Console.ReadLine ();

2.
Please enter your name:
Please enter your age:
If it is greater than or equal to 18 years old, the output: My name is xxx, I am an adult!
If it is less than 18 years old, then output: My name is xxx, I am also underage.

            //receiving information entered by the userConsole.Write ("Please enter your name:"); stringName1 =Console.ReadLine (); Console.Write ("Please enter your age:"); decimalAge1 =Convert.todecimal (Console.ReadLine ()); //compare the derived variables            stringA = (Age1 >= -) ?"Adult! ":"still underage. "; //Output PrintingConsole.WriteLine ("My name"+ name1 +", I"+a); Console.ReadLine ();

3.
Please enter an integer between 10-20:
(This number includes 10 and 20)
Output:
The number you entered is: XXX, enter the correct.
Or
The number you entered is: XXX, input error.

            //receiving information entered by the userConsole.Write ("Please enter a 10-20-room integer (this number contains 10 and a):"); intA =Convert.ToInt32 (Console.ReadLine ()); //compare the derived variables            stringA1 = (A >=Ten&& a <= -) ?", enter correct. ":", enter an error. "; //Output PrintingConsole.WriteLine ("the number you entered is:"+ A +A1); Console.ReadLine ();

4. Please enter an integer between 10-20:
(This number contains 10 and 20, but not equal to 15 and 18)
Output:
The number you entered is: XXX, enter the correct.
Or
The number you entered is: XXX, input error.

            //Accept user-entered informationConsole.Write ("Please enter an integer between 10-20: (this number contains 10 and 20, but not equal to 15 and):"); intA =Convert.ToInt32 (Console.ReadLine ()); //compare the derived variables            stringb = (a >=Ten&& a <= -&& A! = the&& A! = -) ?", enter correct. ":", enter an error. "; //Output PrintingConsole.WriteLine ("the number you entered is:"+ A +b); Console.ReadLine ();

5.
Please enter an integer between the number 0-20:
Cannot be 0, can be 20.
If not 5, the last increase is not 5. ”；
If 5, then the number is within 10. The end
If 15, the last increment is "not 15." ”；
If 15, then in "is the number between 10-20." The end

Note that punctuation should be correct!

Output:
The number you entered is: XXX, entered correctly, is within 10 of the number, not 5.
Or
The number you entered is: XXX, entered correctly, is a number between 10-20, not 15.
Or
The number you entered is: XXX, input Error!

            //receiving information entered by the userConsole.Write ("Please enter an integer between the number 0-20:"); intA =Convert.ToInt32 (Console.ReadLine ()); //compare the derived variables            stringb = (A >0&& a <= -) ?", enter the correct":", input error"; stringc = (A >0&& a <=Ten) ?", is within 10 of the number":""; stringD = (A >Ten&& a <= -) ?", which is a number between 10-20":""; stringE = (A >0&& a <=Ten&& A! =5) ?", not for 5":""; stringf = (A >Ten&& a <= -&& A! = the) ?", not for the":""; //Output PrintingConsole.WriteLine ("the number you entered is:"+ A + B + C + D + E + f +". "); Console.ReadLine ();
