inline functions

Let's say I have a function

func()
{

............
func();
..........
}

I.e it is a recursive function. What happens if I declare it inline

It won't be inlined, or it will only be inlined a certain number of
times.

There is no _requirement_ that the compiler insert inline code at any
given place the function is called.

inline is more of a hint than an instruction, the compiler is at liberty
to ignore 'inline' where it considers inline to be inappropriate. This
would be one of those cases.

inline is merely a hint to the compiler, and it may be ignored.

On a related note, good optimizing compilers can eliminate some
forms of recursion.

Hi, I'm having problems completing a project in C++. I have been using inline functions in some of my header files. I have only done so for simple functions that only have 1 statement (eg. accessor and mutator methods to access private data members). I would like to know if there are any issues with using inline functions that may have attributed to my errors before I start separting them out into "outline functions". Regards

I am not clear with the use of the keyword inline... I believe you add it do a function when you implement the function inside the header file where the class is stored... But is that all? What am I missing? If that's all, then why did Bjarne even bother adding it to the language? If that's not all, what else can I do with "inline"?

Hello, Rules for inline functions say that they have to be defined in the same compilation unit as their declarations. For class member functions this means that the inline member functions must be defined either within the class or within the same header file. But its generally a good programming practice to have the declarations and definitions in seperate files. This would make the future maintenance of the code easier.

Hello experts! I'm reading a book about C++ and there is something about inline that the book says that is unclear for me. The book says the following "Because inline functions are expanded at compile time, definitions of these functions, unlike other definitions, cannot be separately compiled and must be placed in header files. This creates a problem if the compiler does not actually inline a

Hello I have a program with many many inlined template functions It is essential for the execution speed that every (or almost every) function marked as inlined, becomes really inlined by the compiler. I already compiled the program with Intel Compiler (ICL) on Visual C++, and it works fine and fast. I verified that the functions are really inlined. But with GCC 3.4 (Linux+Cygwin) or ICC (Linux), The same program is about 5

Hi Everyone, I have few questions on inline functions, when i declare a function as inline, is it for sure that the compiler would replace the function call with the actual body of the function? or is it a call taken by compiler? Second, i see that it is same as what Macro's used to do for c, if so what is the advantage for going in for inline functions than to Macros?

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Dear forum friends, With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
