Linux supports multiple processes at the same time, which is what we often call multi-channel programming in modern operating systems, so-called at the same time the Linux system scheduling each process to occupy the CPU. Because each time slice

C + + supplements--LAMBDA expression principlePrefaceLambda expressions are presented in the new C++11 standard. In lambda expressions, we focus on the use of it. Now let's talk about how it's implemented.Body1. Function ObjectsThe object of the

each engaged in C + + the development of the friends believe that can give some advice to the latter, but the real summary of this is very little. This article gives the online spread of the C + + programming Development Learning 50 suggestions,

Scene:1. Some frequently used pointer variable address is not aligned, running efficiency and alignment efficiency is very different, so in the creation of heap space, it is necessary to the memory address alignment to improve operational efficiency.

Arithmetic operations There are 34 types of operators in C, including common subtraction operations Addition Operation + Besides being able to do addition operations, it can also represent a plus sign: +5, +90

C + + Supplements--the principle of virtual functionObjectiveC + + 's polymorphism relies on virtual functions to implement. If a class has virtual functions, each instance of the class maintains an address that points to the virtual function table.

The C + + language does not define any input/output (IO) statements and, instead, includes a comprehensive standard library to provide the IO mechanism.Many of the examples in this book use the iostream Library. The iostream library contains two

1. The purpose of the default parameter C + + can define default parameter values for functions. Typically, when a function is called, the corresponding argument is given for each parameter of the function. For example:void delay (int loops);

There are two ordered arrays, a, B, and the lengths are m,n; use an algorithm with a time complexity of m+n to merge the two arrays into an ordered array of C.1 Static voidMain (string[] args)2 {3 int[] A = {1,3,5,6,6,7, - };4

In program development, sometimes it takes a value type to be a nullable type, for example, in a database, we can set a datetime to NULL.Nullable types appear in C # 2.0, allowing value types to also be empty (null), and implementations of nullable

The C language standard library does not have an int substr (char *s1, char *s2)/* String match, successfully returned to the location, the -1*/function is not successfully returned, and the following is a substr function implemented by the existing

C language implementation interface (do not use MFC \ To avoid forgetting), mfc I feel that MFC is not a programmer's detail, and the basic interface is implemented today to avoid forgetting it later. Source code: # Include # Include Char str [] = {'
