vprint

smart pointers, be careful when using pointers as elements of containers, in this case, you need to manage the memory yourself. For example: Example 9: Use the smart pointer shared_ptr In the boost library to wrap the pointer: # Include # Include # Include # Include # Include # Include # Include Using namespace std; Class CTest{Public:CTest (const string str, int iPrice): m_strName (str), m_iPrice (iPrice ){}Void vPrint (){Cout } Private:String m_s

Since it is not possible to put all the code in a file in programming, it is certain that some of the code will be open, so it is not difficult to make a file call in those high-level languages such as c++,c#. So in Lua, These can be achieved as well. The Require function is used primarily. Here is the code to tell you. The file being called Berequired.lua --Private Functions local function myprivatefunction () print ("This is a private function!") End --common interface function

also delete it. This can be done by calling the member function erase () of the container. Example 6: Void main (){Vector Int I; For (I = 0; I {VectInt. push_back (I ); If (3 = I){VectInt. push_back (I );}} VectInt. erase (remove (vectInt. begin (), vectInt. end (), 3), vectInt. end ()); Cout For (I = 0; I {Cout }} The running result is: After deleted, size = 4 // you can see from this line that the container size has changed after deletion. I = 0, 0 I = 1, 1 I = 2, 2 I = 3, 4 The result show

without indentation is the highest level. This indentation is strictly controlled, and the interpreter determines which part of the current code is in terms of indentation, which means that the indentation replaces the curly brace.The next step is to describe how the function is written, first, before the function name, def indicates that it is followed by a function, and then a colon at the end of the parenthesis, and the indentation part is the function content.def printmyname (name): Print N

3.3 DebuggerDebugging is an essential part of the application development process, so it is very important to have a good debugger, unfortunately, Go in this aspect of development is not very perfect. Currently available debuggers are GDB, the latest version is built in the integrated development environment Liteide and Goclipse, but the debugger is not flexible and difficult to operate.If you do not want to use the debugger, you can follow some of the following useful methods to achieve the pur

example, if we want to add a vector to each line of the matrix, we can do that.# Add V to each row of x and store the result in Y X= nd.array ([[1,2,3], [4,6], [7,8,9], [ 10, 11, 12]]) v = nd.array ([1, 0, 1]) y = nd.zeros_like (x) # Create an empty matrix with the same shape as Xfor I in range (4): Y[i,:] = x[i,:] + vprint (y) This is going to work, but when the x matrix is very large, it can be very slow to calculate by using loops. We can c
