-------------------------------------------------- C ++ copy constructor (deep copy, light copy)
For common objects, copying between them is very simple, for example:Int A = 88;Int B =;Different from common objects, class objects have complicated internal structures and various member variables. The following is a simple example of copying a class object.

Ladies and gentlemen, crossing, the last time we talked about the Const keyword example, this time we say the example is:C language Constants . Gossip Hugh, words return to the positive. Let's talk C chestnuts together!Crossing, we introduced the Const keyword in the last time, and we all know that const modifiers are constants. Referring to constants, we often use them in our programs, and in this case we look at other constants in the

Recently in the OPENCV-based license plate recognition, which requires some code for deep learning (python), the development language at the outset chose Python (the source of the scourge).Although the speed of Python is not too slow now, but you must use Python to manipulate the image, when implementing some algorithms, efficiency becomes very important. Unfortunately, Python in most implementations of the algorithm, because its loop operation is too slow, resulting in the implementation of the
Because our students have to earn 24 academic points before they can complete their career, that is, they need to take 8 Education courses. Many senior students have to take 4 courses at a time and take 4 courses at a time, in this way, you can finish all the exercises, and then write your own comments. I was afraid that I could not pay for it. I only dared to repair the three shards conservatively. I planned to complete the three, three, and two repairs in the second round, it would be nice to

Good. Then go deep into the C + + journey. When I was translating the first article. I have learned a lot of things, so I intend to translate this whole PPT to complete.Take a look at the following code snippet:[CPP]
#include
void foo (void)
{
int A;
printf ("%d\n", a);
}
void Bar (void)
{
int a = 42;
}
int Main (void)
{
Bar ();
Foo ();
}

How to batch clear temporary system files (languages: C #, C/C ++, php, python, and java ),
Language competition has been around for a long time. I will do some I/O experiments (traverse more than 9 GB files and delete them in batches) below to compare who is better and who is worse with the facts. OS: win7 64-bit, file package size: 9.68 GB.

Many beginners are accustomed to using char variables to receive the return values of functions such as getchar, GETC, and fgetc. In fact, this is not correct, and it implies a fatal error. The return values of functions such as getchar are int type. When these functions fail to be read or the file is read, EOF is returned. EOF is a macro. The standard specifies that its value must be a negative constant of the int type. Generally, the compiler defines EOF as-1. This is where the problem occurs.

In C #, there are no free functions and no free variables. Everything must be encapsulated in the class. In C ++, using global variables for inter-function communication and inter-class communication are common methods. However, this becomes impossible in C, this indeed makes
