[C ++] C ++ annotations are converted into C annotations.
In a large project, due to the diversity of code personnel, the annotation style of the Code is different. However, in a released version, the annotation style should be consistent so that other personnel can use and maintain it later. As a result, the following requirements are generated:
Implements the

Debugging a breakpoint to see in-memory data is the best method, because C # is on a managed platform, and
How C + + programs play into DLL dynamic libraries:**1. Create a new main.h in VS and add the following: * *extern"C" _declspec (dllexport)IntOnLoad();**2. Create a new main.cpp and include the following. h header, then implement the definition function onload (): * *#Include"MainFunc.h"IntOnLoad(){//func ....} 3. Executes the program, generating corresponding Dll4. Use this dll:i. Declare in the file to be
From deep C (and C + +) by Olve Maudal and Jon Jagger, itself half bucket of water, if any netizen found fault, message points out:
Programming is difficult, and it is especially difficult to correctly use C + + programming. Indeed, it is difficult to see the code that is well defined and written in both C and
Look at the operator overloads of C #, and find that they are not the same as C + +. Just been in the C # self-increment operator pit, now to share.First define a class class A { publicint i; Public A (int i) { = i; } Public Static operator + + +(a A) { returnnew A (+); } } Main functio

AbstractSet the Memory value to the most common control during firmware. This article describes the programming skills that are common when C statements are used for firmware, and correspond to each other with the image watermark.
IntroductionThis article will discuss the following topics:
1. Set a bit counter to 1
2. Set a bit counter to 0
3. Toggle a bit (0 changes to and 0)
4. Determine whether a bit of a shard is 1
5. Determine whether
AbstractTilde is written from the embedding method to C. If you are familiar with the C-speaking language, you will be familiar with the learning method, but it is also similar to the embedding method, if we think about it as a C statement, how can we grasp the hard body spirit.

Learning Summary1. The C base data type uses 11 keywords: int, long, short, unsigned, char, float, double, signed, _bool, _complex, and _imaginary.2. In standard C, integer 0 is false, and integers greater than 0 are true. Char can actually be printed as an integer.3, octal is prefixed with 0, hexadecimal is expressed in 0x or 0X.4, can use the sizeof keyword query type length, if sizeof (int). C99 has a po

Compare the two transfer methods:
To pass variables by value, you need to copy the Real-Time Parameter memory to initialize the parameters. This will incur some overhead. When discussing simple variables, the overhead of built-in types (such as int and float) is negligible, but for large objects (such as large objects representing the whole 3D World, replication costs are high. The C language also provides a pointer to pass by value, which can also so
