Some results are processed on the C # backend and then transmitted to the front-end Javascript or jQuery,

In C # Back-end processing some results are passed to the front-end Javascript or jQuery, the previous Insus. NET has done an example of "to pass the CS value to JS use" http://www.cnblogs.com/insus/archive/2011/05/04/2036271.html is implemented using the Literal control. But it is still complicated. This Insus. NET is simplified, and the value is passed to the front-end jQuery.

The user requests a webpage, sends it to the server, and then sends it to the client. Therefore, it is easy for the server to pass values to jQuery or javascript. Otherwise, it will be difficult.

I just saw a requirement on the website:

 

You can write:

Check the backend. aspx. cs:

 

When running the webpage, you can see:

 

& In C Language

& Can be used as the bitwise AND or address fetch Operator
The following describes two usage methods:
1. bitwise and operation bitwise AND operator "&" are binary operators. Its function is the binary phase corresponding to the two numbers involved in the operation. The result bit is 1 only when the two binary numbers are 1. Otherwise, the result bit is 0. The number of involved operations is supplemented.
For example, 9 & 5 can be written as follows: 00001001 (Binary complement of 9) & 00000101 (Binary complement of 5) 00000001 (Binary complement of 1) Visible 9 & 5 = 1.
Bitwise AND operations are usually used to clear some bits or retain some bits. For example, if a clears the high eight bits of 0 and retains the low eight bits, it can be used as a & 255 operation (255 of the binary number is 0000000011111111 ).
2. Get the address
& As The unary operator, the result is the address of the right operation object.
For example, & x returns the address of x.
The address itself is an abstract concept used to indicate the logical location of an object in the memory.

In C language, how does one express the root number? Thank you!

First, add # include "math. h" to the main () function. Because the root number is a function in the mathematical function, add # inculde "math. h" to use the root number ",
Then add sqrt to the front of the number of root numbers.
For example
# Inculde "math. h"
Main ()
{Float a, B;
Printf ("please input a nuberm :");
Scanf ("% f", & );
B = sqrt ();
Printf ("% f \ n", B );

} This program allows the user to enter a number and then output the result after the root number of the original value.
