What is outline function in c plus plus language?
Outline is the opposite of inline. An inline expanded function is any function or class method where the declaration also provides the definition (the implementation). This is known as implicit inline expansion. Where the definition is kept separate from the declaration, you may use the inline keyword to specifiy that the function should be inline. This is known as explicit inline expansion. Inline expanded functions (whether implied or explicit) does NOT mean the function will in fact be inline expanded. It is merely a suggestion to the compiler. If the compiler's optimisers determine that there is no advantage to be gained by inline expanding a particular function, then that function becomes an outline function. Inline expansion simply means that the body of the function is inserted in place of the function call. Function calls are expensive in terms of memory and performance, so by eliminating the function call completely, your code performs faster and uses less memory. However, functions that are called many times throughout your code will result in a much larger code size, and large code runs slower than small code. Thus the benefit of eliminating a function call has to be weighed against the increased code size. Although some compilers do allow you to override the compiler's inline expansion optimisers, this is strictly non-standard. The best judge of what to expand and what not to expand is best left in the hands of the compiler, and indiscriminate use of the inline keyword should generally be avoided.
What are the rules for inline functions in c plus plus?
When you mark function as inline compiler puts the whole body of function in those places it is called, similar idea as in macros. If you do not mark function as inlinecompiler inside still decides which functions should be inline and which not. Inline function is less performance costly especially if function is called very often. Why it is lest performance costly? Because to invoke function you need to prepare parameters, put them to stack, make jump and etc. and all those steps are eliminated if function is inline.Example (very basic):inline int sum(int a, int b) {return a + b;}int c, d;c = sum(2, 3); /* compiler will change to 2 + 3 */d = sum(2, 5); /* this one will be changed to 2 + 5 */Full inline functions are allowed in ANSI/ISO C99.

What is the difference between inlinefunction and function overloading?
The normal way a function works is that whenever your code encounters a call to the function, it jumps to the body of the function code. An inline function tells the compiler that it should actually copy over the code from a function body into all places where that function is called. In some cases this can cause a dramatic reduction in run time, but in others it causes nothing more than increasing the size of the produced executable. Function overloading refers to the ability to have multiple functions with the same name, but different parameter types.
How does an inline function differ from a preprocessor macro in c?
"Differences between inline functions and non"Non-inline functions are your standard functions. When they're called, the compiler puts all the variables and its current position on the stack, jumps to the location in memory where the function resides, executes the instructions, and jumps back to where it was originally called. All that work takes a lot more time then if you had just not used functions. By writing the code directly into your procedure and not using functions you are inlining your code. If you have that same piece of code in multiple places, maintaining your code will become a problem because your code will be duplicated everywhere (because you're not using functions in order to achieve a speed increase). In order to get the best of both worlds, C++ introduced the inline keyword. By specifying that a function is inline, the compiler will take the function you have written and basically replace the function call that would have been generated with the function itself. In other words, using an inline function is pretty much directly putting your code there, except it's prettier and more maintainable.Overuse of inlining function will cause bloated code for a very marginal increase in speed, if any. Inline functions are best suited for small quick functions. Also note that the inline keyword is a request to inline a function and the compiler may not necessarily honor that request. One example would be attempting to inline a recursive function.In other languages like Java and C#, you are not able to specify what is inlined and what is not. The compiler will automatically make that decision without any input from the programmer.

When does marginal benefit occur?
Marginal benefit 'occurs' for any benefit (price) function, since a marginal term is simply the first-order derivative of its parent function. Marginal benefit is strictly greater than zero only when a benefit function is always increasing in total benefit over its domain.

When will you make a function inline?
Inline functions are ideally suited to small functions, particularly private data member accessors (getters) that simply return values and are called often, as well as functions with only one or two simple statements. These types of functions spend proportionally more time calling and returning than do larger functions and will provide much better performance at the cost of minimal increased code size. Larger, more complex functions are not ideally suited to inline expansion as they spend proportionally less time calling/returning. Even a large function that is only called from one call site will exhibit only marginal benefit. It should be noted that explicitly marking a function for inline expansion, or by implication (such as functions defined in a class declaration), is no guarantee the function will be expanded. It is merely a suggestion to the compiler, marking the function as a candidate for expansion, nothing more. If the compiler's cost/benefit analysis shows the suggestion is profitable, the function will be inline expanded, otherwise it will be instantiated as a normal function call. The __forceinline keyword overrides the cost/benefit analysis, but you cannot force the compiler to inline expand a function, even with __forceinline, if there are other considerations besides cost/benefit, such as security attributes applied to the function, or where the function uses a variable argument list. Moreover, indiscriminate use of __forceinline can result in larger code with only marginal performance gains, or a loss of performance as a result of increased paging, for example. Put simply, smaller code executes quicker overall, but trial and error with high performance timers will ultimately tell you of inline expansion is actually beneficial. Note that if the function or its caller is compiled for debugging, the compiler cannot inline expand the function. Simple recursive functions can sometimes benefit from inline expansion, if the compiler allows it, however this feature will be limited to a predetermined depth. In VC++, for instance, you can use the inline_recursion pragma to control inline expansion while the depth can be modified via the inline_depth pragma up to a maximum of 16 recursions. Any additional recursions will be treated as instance calls to the function instead.
What purpose does php mail serve?
PHP mail has a variety of functions. The main function is to reroute mail from one server to another. The benefit of doing this is so one doesn't overload the current server.
