C ++FunctionAdvanced features Compared with C functions, C ++ adds four new mechanisms: overloaded, inline, const, and virtual. The overload and inline mechanisms can be used for both global functions and class member functions. The const and virtual mechanisms are only used for class member functions. Heavy Load and inline will certainly have their advantages to

Aunt Objective-C:C # Hello, little sister! # Import C # sister:Aunt Objective-C! Using System; namespace CSharpToObjectiveC {class Program {static void Main (string [] args) {Console. WriteLine ("Objective-C aunt! ");}}} C # sister:Aunt, you see our code is very similar. Aunt Objective-C:Yes, we are all relatives of

The intent of extern "C" in C + + is to implement mixed programming between C + + and C and other languages.C + + to support overloading of functions. C + + has a distinct difference in the way global functions are handled.For the function void foo (int x, int y), the functi

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

Today we will discuss several questions about C/C ++. Inline functions When it comes to inline functions, let's take a look at the following twoProgramThe program execution enchantment is to get the sum of the two values: // Procedure 1 Int Add ( Int X, Int Y){ Return X + Y;} Int Main (Int Argc, Char * Argv []){ Int A = 1 , B = 2 , C;

C # basic syntax differences between c # And c ++ Data TypesBasic Data Type: In c #, sbyte indicates-128 ~ An integer between 127, which is the same as the char of the c ++ crowd; byte in c # indicates 0 ~ An integer between 255,

The case, how to compile, l

C + + pseudo function:The so-called pseudo-function means that it is not a real function, but a class or a struct.Like the Say_hello () call in code is the function call we normally use, and we use the p defined by Hello,and then P (), which is what we call pseudo-functions. What are the benefits or advantages of pseudo-functions?Its advantage is that it can be passed. As defined by Hello, it is like a variable,Convenient, and can also be called by ot

, nonzero, which is true 2, nonzero, true, Truetrue = True The result is true. The whole process of operation needs to be transformed. The binary direct comparison of operands is not directly used. So the results are different. At the time of comparison, true should be converted to a binary value like 11111111, false may turn into 00000000. The is the same here, that is, for an operand. 's operand is true/false regardless of what type of expression you are using, he first converts to one
