An inline function in C++ prompts the compiler to insert or in-line the code whenever the function is called. This reduces execution time and overhead function call times. We use the inline keyword to define these functions. 23 mins read An inline function in C++ programming is a special ...
NOTE- This is just a suggestion to compiler to make the function inline, if function is big (in term of executable instruction etc) then, compiler can ignore the “inline” request and treat the function as normal function. 什么是内联函数: 内联函数是一种C++增强功能,可以增加程序的运行时间。
Why to use –In many places we create the functions for small work/functionality which contain simple and less number of executable instruction. Imagine their calling overhead each time they are being called by callers.When a normal function call instruction is encountered, the program stores the...
In C, we have used Macro function an optimized technique used by compiler to reduce the execution time etc. So Question comes in mind that what’s there in C++ for that and in what all better ways? Inline function is introduced which is an optimization technique used by the compilers espec...
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- ...

A member function can also be declared as inline function, use the inline keyword before function declaration and definition, if function definition is written outside of class. Example In the below example,square()andaverage()are the inline functions inside the class (with in the class). ...
When we use an inline function, the size of the code is increased because the compiler replaces each function call with the inline function code. Large sized code takes more memory and time to compiler the code. The compilation process slows down because the compiler evaluates and replaces the...
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 theory, using inline functions can make your program faster because they eliminate the overhead...
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 use inline function to eliminate the cost of...
