Although inline functions are similar to macros (because the function code is expanded at the point of the call at compile time), inline functions are parsed by the compiler, whereas macros are expanded by the preprocessor. As a result, there are several important differences: Inline functions f...
inline function内联函数macro宏You should use an inline function when you wish to optimize function calls. You may consider an inline function as a macro th
Inline functions vs. macros A macro has some things in common with aninlinefunction. But there are important differences. Consider the following example: C++ #include<iostream>#definemult1(a, b) a * b#definemult2(a, b) (a) * (b)#definemult3(a, b) ((a) * (b))inlineintmultiply(...
An inline function in C++ is a special function that reduces call overhead. It signals the compiler to expand the function code in-line where it is called.
Comparison between macro vs inline function in C. inline function is Compile time and macro is preprocessing time. Example of compilation error.
macro Vs inline The C/C++ style, macros without arguments should look like variable or other identifiers, macros with arguments should look like function calls. so any difference between macro and inline? #defineSQUARE(x) ((x)*(x)) inlineintsquare(intx) {returnx*x;}...
