return method, and more values can be returned. The following example naturally understands: # Include "iostream. h" Void example (int * a1, int b1, int c1) { * A1 * = 3; ++ B1; + + C1; } Void main () { Int *; Int B, c; * A = 6; B = 7; c = 10; Example (a, B, c ); Cout "* a =" * a Cout "B =" Cout "c =" } Output: * a = 18 B = 8 C = 10 Note that No, * the values of a and B have changed, but c has not chan

return value is expressed in radians (the return value is greater than-pi and less than or equal to pi).Example:ATAN2 ( -2,2) equals 2.356194490 (3*pi/4 in radians).ATAN2 (2,2) equals 0.785398163 (Pi/4 in radians).ATAN2 ( -2,2) *180/pi () equals 135 (angle system).AVERAGEAVERAGE (Number1,number2,...): Returns the average of the specified data.Number1,number2: The parameter used to calculate the mean.Note:The argument must be a number, or a name, array, or reference that contains a number.If the

game theory (i): Nim Games Key conclusion: For a Nim game situation (A1,a2,..., an), it is p-position when and only A1^a2^...^an=0, where ^ represents a bitwise XOR or (XOR) operation. Nim game is one of the most classic models in game theory. , it has a very simple rule and a very beautiful conclusion, from the game began to understand the game theory is probably the most appropriate.Nim game is a combina

are equal, use the following statement:Return (a ^ B) = 0)Example 2: the implementation of the initial functions 6_addr_equal () in Linux is as follows:Static inline int ipv6_addr_equal (const struct in6_addr * A1, const struct in6_addr * A2){Return (A1-> s6_addr32 [0] = a2-> s6_addr32 [0] A1-> s6_addr32 [1] = a2-> s6_addr32 [1]

example, the implementation of the initial ipv6_addr_equal () function in 2:linux is as follows:static inline int ipv6_addr_equal (const struct IN6_ADDR *a1, const struct IN6_ADDR *a2){Return (a1->s6_addr32[0] = = A2->s6_addr32[0] A1-GT;S6_ADDR32[1] = = A2->s6_addr32[1] A1-GT;S6_ADDR32[2] = = A2->s6_addr32[2]

Positive kinematics solution of robot based on DH parameter method Two Conventions for the establishment of a coordinate system using the DH parameter method: ( 1 ) x_i and Z_ (i-1) Vertical ( 2 ) intersection of X_i and Z_ (i-1) The second transformation matrix of the coordinate system I and the coordinate system i-1 is: NBSP; A is a distance of two z-axis, and D is the distance of two x-axis. NBSP; alpha and Theta's Square conventions are:

method, multiplying by 2 numbers of any number of digits:Multiply A * b for 2 numbers of any number of digits, written as:A = A1 * 10^ (N1/2) + a0-----N1 is a number of digitsb = B1 * 10^ (N2/2) + B0-----N2 is a bit of BThe divide-and-conquer strategy is based on the above transformation, a, B is written in the form of the first half of the number and the last half of the number, for example, if a = 5423678, then

look at the href attribute/feature. First, create a Execute the following code in the JS script: console.log(a1.href); // 'file:///D:/GitHub/JS/html/test_01/page_1.html'console.log(a1.getAttribute('href')); // 'page_1.html' We can see that the absolute path is saved in property, and the relative path is saved in attribute. So what happens if these values are changed? Change attribute:

distinguish between the PHP program output and logger output information is different, here first output a message. 5. A logger class is obtained by using the GetLogger () static method of the Loggermanager class, whose arguments are typically class names, which are used to distinguish different logger records, where we only use a test class, So this name we can define as test, of course you can also define as Test1, test2 ... 6. If $str is not empty, output a debug message 7. If $STR is lon

Learning Java students know that sun for us to encapsulate a lot of commonly used classes, this chapter for you to summarize the classes we often use. Previous blog A friend of a message asked me if the string is a reference data type? I found out that string belongs to the application data type by finding the data, so let's start by looking at the string class.1. String classThe Java.long.String class represents the immutable sequence of characters. Examples of string classes: Public classSTR {
