Urge reading, summarize the essence, refining notes, a point, there are inappropriate places, welcome message.Both C and C + + arrays and pointers are low-level composite data types, such as arrays of C + +, like vector containers, and pointers like iterators. Low-level data types have the advantage of being fast. But error prone, not good debugging. Modern

Mutual reference between C and C ++ functions extern "C" for an in-depth understanding 1. Introduction C ++ language was originally created as "a better C ", however, this does not mean that the compilation and connection methods used by global variables and functions simila

Item m34: how to mix C ++ and C in the same program For many years, you have been worried about using C ++ in part during programming, just as using multiple compilers to generate programs in the age of all C programming. There is no way to program Multiple compilers, unless different compilers have the same implementa

The macros you encounter are for conditional compilation. In general, all rows in the source program participate in the compilation. But sometimes it is desirable to compile a portion of the content only if it satisfies a certain condition, that is, to specify the condition of compilation for a portion of the content, which is conditional compilation. Sometimes, you want to compile a set of statements when a condition is met, and compile another set of statements when the condition is not satisf

1. Is the C Runtime Library the same thing as the C function library (such as stdio. h and stdlib. h?2. In the technical reference books, I often say "Microsoft C Runtime Library". Is the C Runtime Library a language database or an operating system database? Do other operating systems, such as Unix/Linux, have

Transferred from: http://blog.csdn.net/ljfth/article/details/3965871The first kind of understandingFor example, you have developed a DLL library in C + +, in order for C to be able to call your DLL output (export) function, you need to use extern "C" to force the compiler not to modify yourThe function name.Typically, a code similar to the following is often seen

In the C language, " data" and "operations (functions) that manipulate data" are declared separately. is driven by a set of algorithms that are "distributed across function-oriented functions," and work with common external data.Let's look at an example:If we declare a struct Point3D,typedef struct POINT3D{FLOAT x;float y;float z;} Point3D;To print a Point3D, you might have to define a function like this:Voidpoint3d_print (const Point3D *PD) {printf (

SETJMP and longjmp non-localized jump statements: Nonlocal refers to, this is not similar to the normal C language goto statement, the statement in a function to jump, but on the stack to jump, may skip many call frames, and then return to the current function call path in a function. Use setjmp and longjmp where you need attention:1) setjmp and longjmp are used in combination, have their corresponding call order, setjmp before, longjmp in order to be
