C++

My growth path of C + + Blink of an eye, a year of C + + learning is over, from the beginning of the do not understand the constant contact learning, gradually understand some of the knowledge of C + +. Freshman Semester C + + learning is not good,

In assembly language there is direct to the operation of the instructions, such as the position, reset, bit to reverse, test one, etc., this is very convenient for hardware operation, in C language Although also provides some bit manipulation means,

#include #include #include #include using namespace std; Implement Singleton mode //Design a class, we can only generate one instance of the class. class Singleton {public : Static Singleton * getinstance () {

In embedded system, dynamic memory request exists more stringent requirements than the general system programming, because the memory space of embedded system is very limited, and the inadvertent memory leak will quickly cause the system to crash.

With parallel programming, you can operate multiple delegates at the same time, and briefly introduce two generic delegate system.func<> and system.action<> before introducing parallel programming. Func<> is a generic delegate that accepts multiple

The use of Pthread_create int Pthread_create (pthread_t*, const pthread_attr_t*, void* (*) (void*), void*) To make the g++ compile, the following methods are: C + + prohibits assigning void pointers to other pointers at random.So you get an

Hint: This method can be used in the Qtc++ program and QTQML data exchange First initialization: Ddocumentsets::getinstance ()->setmodel (Oa_model); This example can be obtained in any future class: Ddocumentset*oa_model=ddocumentsets::getinstance (

Explicit function: In C + +, the explicit keyword is used to modify the constructor of the class, the class of the constructor that is decorated, the corresponding implicit type conversion cannot occur, and the type conversion can only be done in a

If you want to copy a sequence (sequence) to a container (container), usually use the std::copy algorithm, the code is as follows: Std::copy (Start, End, Std::back_inserter (container));Here, start and end are the iterator (iterator) of the input
