Step 5: create a shared library file
Next, we will create a localCode.
In addition to creating executable machine code files, most C and C ++ compilers can also create shared library files.
The command used to create shared library files

Note: classes that contain dynamically assigned members should provide copy constructors and overload the "=" value assignment operator.
The following examples will be used:Class cexample{Public:Cexample ()
Personal implementation example:
# Include # include # define M 4 int add (int A, int B); int sub (int A, int B ); int MUL (int A, int B); int Div (int A, int B); int (* oper_func []) (INT, INT) ={ Add, sub, Mul, div }; char
Now let's look at the following equivalence relationships:
Static in C # and static in Java
Simple. The two are used in the same way. The following two aspects are discussed:
1.Variables belong to the class, not the instance level. It can only be
01. It is also a ch00. In my personal sense, it is a good habit for programmers to count from 0, and it is also a kind of sorrow.
02. Good habits are because he already has computer thinking. Sadly, people are not machines.
03. When I am alone in
After several rounds of interviews, I will summarize the questions frequently asked during the interview:
1. What is the difference between iPad development and iPhone development?
A: The development of iPad and iPhone applications use the same SDK.
Step 1: Write Java codeStarting from writing a Java source code file, it will declare the local method (or method), load the shared library containing the local code, and then actually call the local method.
Here is jni_javacallc_test:

A problem was encountered before: the customer asked their program to install on PPC after the program name is Chinese, but when the cab package contains Unicode, there will be the following error:
Error: The inf file contains Unicode characters
When I was doing ACM, I often encountered some big integers. The commonly used built-in integer types are often too small: Long and intThe value range is [-2 ^ 31,2 ^ 31), that is,-2147483648 ~ 2147483647. The unsigned range is [0, 2 ^ 32), that is0
1. Basic explanation
Extern can be placed before a variable or function to indicate that the definition of a variable or function is in another file, prompting the compiler to find its definition in other modules when it encounters this variable or
Preface:
If you are familiar with C language, you should be familiar with macros. macros are often used in C language programming. The main purpose of using macros is to facilitate programming for programmers, in addition, the program efficiency
1. File opening function: fopen
Call method: file pointer name = fopen (File Name (PATH), file method)
Eg: file * FP;
Fp = fopen ("file1.bat", "rb ");
File Usage
"RT" only opens a text file and only supports reading data.
"WT" can only open or
Q: Define a macro to compare the sizes of two numbers A and B. The statements greater than, less than, and if cannot be used.A: Define max (a, B) (a/B )? A: B

As long as the GPS receiver is in the working state, it will continuously transmit the received and computed GPS navigation and positioning information to the computer through the serial port. The previous code is only responsible for receiving data
The mstpscap. c file is used to capture packets on the MS/TP protocol from the serial port. The format for testing is: mstsnap [Serial] [baud] [network]
The default parameters are serial port/dev/ttyusb0, baud rate is 38400, and eth0.

In the compilation makefile of the LED driver programming of the fl2440 data, the-C indicates that the makefile is executed in the $ (kerneldir) directory, while M is not the makefile option, is the variable used in makefile under the kernel root
1. Multiplication Operator
2. Define pointersInt * p = 0; or int * p = 0 ;? The latter is easier to understand: defines a Variable P, which is pointer-type (more detailed, it is pointer-type pointing to int, the previous definition seems to
