1028, micro-innovation topic announcement

At 3 o'clock in the afternoon, the lady said that Miss Minimally invasive software company, asked me to go to their company's written test, apply the software engineer, I asked the situation, I promised it, it is good to be a good experience. of. So, I was riding a small electric donkey for 50 minutes, I found the Tower Tower Center, No. 222, Ya'an East Road, the building is very PP, a very high-grade office building, into and out, the work environment is very good, I look at myself Casual clothes, I am really embarrassed to go in, this building is still troublesome, you have to sign the leader. Finally, I finally got on the 21st floor, I saw the company's facade, very style, my favorite yellow is decorated, comfortable. However, the reception is not the company employee, two security guards wearing uniform, handed me a test, led me into a meeting room, and said to me after 90 minutes. Then I went out. There are many people in the conference room, except for me and another girl, the rest is a boys, all in the pen! Cattle! I saw the title only stupid ~~~ It is not with my post. The only thing to do is to take the topic as an experience! But I still made a part.嘻嘻

The title is posted, there is no answer, everyone can discuss :)

Part a

1) Realize String tohex (int) to convert a decimal into hexadecimal. (Completely used algorithm)

2) Implement a function String Multiply (Sting, String) that calculates the multiplier (such as more than 100 digits). (Please use algorithm implementation)

3) There are two tables in a database, a table is Customer, a field ID, Name, a table as Order, a field ID, Customerid (foreign key to the ID of Customer), Revenue; write for each Customer's Revenue sum SQL statement.

4) A student grade registration system, where students and courses are additional, please design a library table structure, try to ensure that the system uses the library table structure no longer change.

5) Please briefly describe your most familiar technical architecture, including various middleware in the architecture. (Recommended to use the form of the figure)

Part B

1) Please briefly describe the difference between Critical Section and Mutex.

2) Please describe the role of each constrament in the following function declaration: const char * test () Const

3) Advance more than 3 ASP.NET and ASP.

4) Differences in User Control and Custom Control in ASP.NET.

5) Use a C language to delete the function of the head element of the single-strand table, find out the problems and correct it.

Void removehead (node ​​* head) {free (head) head = head-> next}

6) Test write write function to determine whether the byte storage order of the computer is Little Endian or descending (BiGendian)

7) Given the following SQL Database: Test (NUM INT (4)) Use a SQL statement to return Num minimum, but do not use statistics, such as Min, Max, etc.

8) Output the results below.

#include using namespace std; class a {public: Virtual void print (void) {cout << "A :: print () << endl;};}; class b: public a {public: Virtual void print (void) {cout << "B :: Print ()" << endl;};}; class c: public a {public: void print (void) {cout << "C :: print () << Endl;};}; void print (a a) {a.print ();} void main (void) {a a, * pa, * pb, * pc; b; c C; PA = & A PB = & B; PC = & C; a.print (); b.Print (); c.Print (); PA-> print (); pb-> print (); pc-> print (); print a); Print (b); print (c);} The last question I compiled, the result:

Compile Results: A :: Print () B :: Print () C :: Print () A :: Print () B :: Print () C :: Print () A :: Print () A :: Print ) A :: Print ()
