Advantage: Macros and Inline functions are efficient than calling a normal function. The times spend in calling the function is saved in case of macros and inline functions as these are included directly into the code.

Disadvantage: Macros and inline functions increased the size of executable code.

Difference in inline functions and macro
1) Macro is expanded by preprocessor and inline function are expanded by compiler.
2) Expressions passed as arguments to inline functions are evaluated only once while _expression passed as argument to inline functions are evaluated more than once.

More over inline functions are used to overcome the overhead of function calls. Macros are used to maintain the readbility and easy maintainence of the code.

What are the advantages of using inline functions?

Suppose that you wish to write a function in C to compute the maximum of two numbers. One way would be to say: . int max(int a, int b){return (a > b ? a : b);}.
