Random Number again
Now you are determined to squeeze the last drop of the Random function, you may retrieve multiple Random records at a time or want to use records within a certain Random range. By extending the standard Random example above, you can use SQL to cope with the above two situations.
To retrieve several randomly selected records and place t

Pointer definition:
A pointer is a composite data type. It is a description of a type of variable. It's like the street number! For example, there is an X Street with 1024 houses. Then, each house can be indexed using X [0-1024. If every house can save an integer value, there will be 1024 different Integer Variables in street X. In addition, each variable can be accessed using the house number. In fact, the number of each house here is a pointer! If we change X to memory, and each house is regar
a = 99; int * pa = a; int ** ppa = ;}
Hey! That's all right! Actually! This write is also incorrect, because the address to get the variable is an address constant, and the address constant cannot get the address! We can only get address characters for things with memory space!
So the correct one should be like this:
Void main () {int a = 99; int * pa = a; int ** ppa = pa ;}
Next let's look at a program. This program understands what the second-level pointer is:
Now let's look at one row:
Because when I was playing a single-chip microcomputer, I always thought that I could be a host computer.ProgramThere is no need for perfection, there is a simple human-computer interaction interface, and can communicate with the single chip microcomputer.
The specific process is that the user operates on the host computer program, and then interacts with the microcontroller through serial communication, and the microcontroller then responds by controlling various peripherals.

! It tells us that a person wants to take a bus to the State of Chu. Because he chooses the opposite direction and does not listen to others' advice, he can only get farther and farther away from the State of Chu. It tells us that no matter what we do, we must first look at the direction to make full use of our favorable conditions. If the direction is wrong, the favorable conditions will only play the opposite role. Actually! The earth is round! Just as if you choose the opposite direction, as
