The reason that inline functions are an important addition to C++ is that they allow you to create very efficient code Since classes typically require several frequently executed interface functions (which provide access to private data), the efficiency of these functions is of critical concern As you probably know, each time a function is called, a significant amount of overhead is generated by the calling and return mechanism Typically, arguments are pushed onto the stack and various registers are saved when a function is called, and then restored when the function returns The trouble is that these instructions take time However, when a function is expanded in line, none of those operations occur Although expanding function calls in line can produce faster run times, it can also result in larger code size because of duplicated code For this reason, it is best to inline only very small functions Further, it is also a good idea to inline only those functions that will have significant impact on the performance of your program Like the register specifier, inline is actually just a request, not a command, to the compiler The compiler can choose to ignore it Also, some compilers may not inline

all types of functions For example, it is common for a compiler not to inline a recursive function You will need to check your compiler's documentation for any restrictions to inline Remember, if a function cannot be inlined, it will simply be called as a normal function Inline functions may be class member functions For example, this is a perfectly valid C++ program:

Defining Inline Functions Within a Class
It is possible to define short functions completely within a class declaration When a function is defined inside a class declaration, it is automatically made into an inline function (if possible) It is not necessary (but not an error) to precede its declaration with the inline keyword For example, the preceding program is rewritten here with the definitions of init( ) and show( ) contained within the declaration of myclass:
#include <iostream> using namespace std; class myclass { int a, b; public: // automatic inline void init(int i, int j) { a=i; b=j; } void show() { cout << a << " " << b << "\n"; } }; int main() { myclass x; xinit(10, 20); xshow(); return 0; }
Notice the format of the function code within myclass Because inline functions are often short, this style of coding within a class is fairly typical However, you are free to use any format you like For example, this is a perfectly valid way to rewrite the myclass declaration:
#include <iostream> using namespace std; class myclass { int a, b; public: // automatic inline void init(int i, int j) { a = i;
