constant object is created, the data in the object cannot be modified, which reduces errors caused by data modification. In addition, because the object remains unchanged, there is no need to lock the object to be read at the same time in the multi-task environment. When writing a program, if we can design a constant object, we should try to design it as a constant object.Variable parameters Variable parameters can also be defined in Python functions. As the name suggests, a variable parameter

systems are/usr/lib/,/lib, and/usr/local/lib. This also depends on the specific system version, it can also be divided into 32-bit and 64-bit paths. The following is a specific example.Practice: Follow these steps to create a file: 1> Create a calc. h file and enter the following code: 　　 #ifndef CALC_H#define CALC_Hdouble Add(double a,double b);#endif 2> Create the Calc. c file and enter the following cod

relative to the parent element, but not very accurate.1, for the general positioning element is our understanding of the parent element2. For Position:absolute, the element is relative to the positioned parent element (offset parent)3. For position:fixed, the element is relative to ViewPortViewport: The visual window, which is the size of the browser windows.Exceptional cases1, the use of padding, margin, etc., the actual percentage and the percentage you want is different. (For this, one of th

inside the object cannot be modified, which reduces the error caused by modifying the data. In addition, because the object is not changed, the simultaneous reading of objects in a multitasking environment does not require locking, while reading a little bit of a problem. When we are writing a program, if we can design a constant object, we try to design it as an immutable object.Variable parametersIn the Python function, you can also define mutable parameters. As the name implies, the variable

1. Position parameters: General Parameters2. Default parameters:1 def Power (x, n=2):2 s = 13while n > 0:4 n = n-15 s = S * x6 return sThere is a default assignment in the parameter, and the Power (5) is the square when called, if Power (5, 3) is cubic.If you have more than one default parameter, the call is preceded by a default parameter, followed by a default argument, you need to write out "parameter name = parameter value" in the calling statement, such as the f

pointer is, of course, the generalized definition of any class object that defines operator () can be considered a function object. (Documents found)In fact, to be straightforward, it is an object (struct or class) that is not a function but has functions and uses the same function.Here's a chestnut (function function with structure):1 /*about C + + profiling functions*/2#include 3#include 4 using namespacestd;5 using namespacestd::p laceholders; 6 7Template 8 structCalc9 {Ten voidAdd (R1 a

First, exception handlingIn the process of running the program, you will always encounter a variety of errors. Program An error stopped running, then we can not let the program stop running it, this time we need to catch the exception, by catching the exception, we do the corresponding processing.Let's begin by writing a function that implements the division operation.def Calc (A, b ): return /print(Calc
