Code Example: #include<iostream> using namespace std; // Use the keyword "inline" to define an inline function inline int sum(int a, int b) { // Definition of inline function return a + b; } int main() { int a = 10, b = 30; int result = sum(a, b); // Function call to...
The C++ inline function provides an alternative. With inline keyword, the compiler replaces the function call statement with the function code itself (process called expansion) and then compiles the entire code. Thus, with inline functions, the compiler does not have to jump to another location ...
Example inline, __inline, and __forceinline When to use inline functions Inline functions vs. macros See also Theinlinekeyword suggests that the compiler substitute the code within the function definition in place of each call to that function. ...
in C, the definitions may be different, and depending on the differences only results in unspecified behavior). On the other hand, C++ allows non-const function-local statics and all function-local statics from different definitions of an inline function are the same in C++ but distinct in C...
To make any function as inline, start its definitions with the keyword “inline”. Example – 12345678910111213141516171819 Class A { Public: inline int add(int a, int b) { return (a + b); }; } Class A { Public: int add(int a, int b); }; inline int A::add(int a, int b) ...
C/C++: Inline function, calloc 对比 malloc Inline function is like a macro definition. When it was be called in another function, the control right will not be changed to this function. The compiler will just replace the line of inline function with the actual content of the function. We ...
Example 1 // inline_keyword1.cpp // compile with: /c inline int max( int a , int b ) { if( a > b ) return a; return b; } A class's member functions can be declared inline either by using theinlinekeyword or by placing the function definition within the class definition. ...
5. Sometimes not useful for example in embedded system where large executable size is not preferred at all due to memory constraints. When to use - Function can be made as inline as per programmer need. Some useful recommendation are mentioned below- ...

For example: c inline int max(int a, int b) { return (a > b) ? a : b; } The compiler inlines a function qualified with inline only if it is reasonable to do so. It is free to ignore the hint if inlining the function adversely affects performance. Note :The __inline keyword ...
