What is an inline function
Inline functions are a programming language feature that tells the compiler to insert the function's code at the call point when the function is called, rather than executing it through a function call. The purpose of inline functions is to improve program execution efficiency and reduce the cost of function calls. The use of inline functions requires a trade-off between code size and execution efficiency. Although inline functions can improve the execution efficiency of the program, they will also increase the size of the code. If the code of the inline function is longer, the size of the program will increase. It may affect the cache hit rate, thereby reducing the execution efficiency of the program.

When to use inline functions in C/C++ and when not to use it?In C++, there is a great feature called inline functions. This function is similar to a C or C++ macro. To use inline functions, we have to specify the inline keyword. We can use this type of function anywhere, but we should follow some guidelines. When can I use inline functions? Inline functions can be used in the position of macros (#define). For small functions, we can use inline functions. It creates faster code and smaller executable files. We can use inline functions when the function is small and called frequently. When should you avoid using inline functions? We should not use I/O bound functions as inline functions. When a large amount of code is used in a function, we should avoid using
In C language, what is an inline function?Inline functions can be replaced where the function call occurs. Function substitution is always the compiler's choice. In an inline function, the function call is replaced by the actual program code. Most inline functions are used for small calculations. They are not suitable for large calculations. Inline functions are similar to ordinary functions. The only difference is that we put a keyword inline before the function name. Inline functions are created using the following syntax -inlinefunction_name(){ //functiondefinition}ExampleThe following is an inline function for a C program: #includeinlineint
