Inline functions :

• processed at compile time
• Its just a hint to comiler, compiler may ignore if it found code is not suitable for inlining
• no side affects
• easy to understand
• type checking applied to function args
• If u are trying to take address of a inline function, inlining will be ignored by compiler
• If ur inlined code contains complex loops and all, inlining will be ignored
• Ignoring inlining depends on comiler

Macros :

• processed at preprocessor stage
• produce unknown side affects
• not that easy to understand
• no type checking appiled for function args

Are macros useless

U can pass any type of argument to a macro (which can be achieved by using templates)
