How does job's tears go to the central black spot

1. DOS uses a segmented structure to address the computer's memory. Each physical storage location has a related address that can be accessed by segment offset. For example, the following is a typical segment address: a000:1234 the part to the left of the colon represents the segment address (a000), and the part to the right of the colon represents the offset from the segment address. Every program in DOS accesses memory in this way, although the mechanism of segment offset addressing method is hidden to most C programmers. When your program is executed, a data segment address stored in the data segment (DS) register is assigned to your program. The default data segment address points to a 64KB memory space, which is usually called short range data segment. In this short-range data segment space, you will find the program stack, static data and short-range heap. Short range heap is used to allocate memory for global variables and other data elements needed for program startup. Any data allocated in this space is called short range data. For example, the following program allocates 32KB of short-range data from the short-range heap when the program starts: / * Note: program uses the medium memory model... * / # include & lt; stdio. h> # include < alloc. h> # include < string. h> # include < stdlib. h> # include < dos. h> void main(void) ; void main(void) { char * near_ data; near_ data= (char * )malloc((32 * 1024) * sizeof(char)) ; if (near data= = (char * )NULL) { printf(" Whoopsie ! Malloc failed! &# 92; n") ; exit(l) ; } strcpy (near_ data, " This string is going to be. stored in the near heap") ; printf(" Address of near_ data : %P\ n",& near_ data) ; free (near_ data) ; } In the above example, near_ Data is a character pointer to which the program allocates a 32KB memory block. By default, this 32KB memory block is allocated from the short range heap, and the corresponding 16 bit address is stored in the character pointer near_ Data. Now, you already know what short-range data is, but you may not understand what remote data is. Very simple, remote data is the data outside the default data segment (the first 64KB data segment). The program in the following example allocates 32KB of space from the remote data area (usually called the remote heap): / * n ote:Program uses the Medium memory model... * / # include < stdio. h> # include < alloc. h> # include < string. h> # include < stdlib. h> # include < dos. h> void main(void) ; void main(void) { char far * far_ data; far_ data= (char far * )farmalloc((32 * 1024) * sizeof(char)) ; if (far data= = (char far*)NULL) { printf (" Whoopsie ! Far malloc failed ! &# 92; n") ; exit (1) ; } fstrcpy(far data, " This string is going to be stored in the far heap"); printf(" Address of far_ data : %Fp\ n",& far_ data) ; farfree (far_ data) ; } In this example, the remote character pointer is given a 32-bit address, which corresponds to a 32KB block of available memory in the remote heap. Note that in order to explicitly allocate memory from the remote heap, a far pointer must be used, so the remote modifier (far) is added to the character pointer definition in the above example. In addition, you should also note that some functions that allocate memory from the remote heap (faroreleft(), farmalloe(), farfree()) are different from those that allocate memory from the short-range heap. The available memory in the remote heap is usually much more than that in the short-range heap because the short-range heap is limited to 64KB. If you compile and run the previous two examples on your computer, you will find that the first example (allocating memory from the short range heap) has about 63kb of available memory, while the second example (allocating memory from the remote heap) has about 400KB to 600KB of available memory (depending on your computer configuration). Therefore, if your program needs a lot of memory to store data, you should use the remote heap instead of the short-range heap. No matter which storage mode is used (except tiny storage mode), you can use the near and far modifiers and the corresponding short-range and remote functions to explicitly allocate memory from the short-range heap and the remote heap. Reasonable use of short-range and remote data will help to improve the efficiency of the program and rece the risk of running out of memory. Note that because DOS uses segment address structure addressing mechanism, the concepts of short-range and remote data are unique to PCs running DOS. Other operating systems, such as UNIX and wndows NT, use flat address mechanism and have no short-range or remote restrictions

2. It is mainly to make a circle whose center angle is the angle between the two ends of the slider. Make parallel line according to the offset, you can get the crank to fix the position of the rack, and it's easy to do in the back...

3. An enterprise shall, within 30 days from the date when the administrative department for Instry and Commerce handles the change of registration, go through the change of social insurance registration with the original social insurance registration institution on the strength of the application for change of social insurance registration, the instrial and commercial license, the instrial and commercial change registration form, the social insurance registration certificate and other materials specified by the social insurance agencies of provinces, autonomous regions and municipalities directly under the central government
first, we should register the social security, carry business license, organization code certificate (when the business license has been handled by the quality and Technical Supervision Bureau), the legal person Id number, tax registration certificate to the social security center for social security registration.
after social security registration, you can apply for social security
1. Sign labor contract
2. Apply for employment registration certificate. How to deal with & lt How to deal with the employment registration certificate and how to make it up after it is lost & gt
3. New insured persons file in the Social Security Bureau, generate social security number, collect avatars and apply for labor security card. This link is handled by the employee himself
4. Fill in and seal the labor contract record form
5. Take 1, 2 and 4 to the Social Security Bureau for labor record, and get a sealed record form
6. Take 5 to the insurance office to fill in the register of social insurance employees in triplicate with seal. Before did not participate in the insurance, the indivial system labor insurance card receipt to him, has participated in the insurance to hand in a piece of original unit to the social security settlement sheet
7. Go to the medical insurance center to hand in the medical insurance and fill in the form.

4. Travel speed variation coefficient = (180 + extreme angle) / (180 extreme angle)

5. You can go to the window and ask about it. There will be a social security supplementary payment form, just fill in it according to the above.

6. Hello, far near live. Among the three words, live is different from the other two words
far and near mean distance, while live means living
if you are satisfied, please accept. Thank you.

7. After the successful online application, the new staff can go to the window to hand in the materials! The required materials are two copies of the personal information registration form with photos (stamped with the company's official seal), one of which is a of the front of the ID card pasted on the back of the personal information registration form (the ID card should be printed in the central position of A4 paper as far as possible) (the word side should face out when pasting), and the insured should add two copies of the form with official seal! Then take the of the first page of the household register of the new insured, the of the personal page, the of the ID card (this is the front and back of the ID card). These copies need to be stamped with the company's official seal!

8. Near can also be used as a verb. We will learn when the verb means near past tense and the participle is near
