A Macro is a preprocessor directive means that before compilation the macros are replaced. Where as typedef is defining a new data type which is same as the existing data type. Syntax: typedef Existing datatype New datatype For example typedef int NUMBER; Here NUMBER (New datatype)is defined as a data type which contains the properties same as int(Existing datatype). You can declare a variable of int as NUMBER a; is same as int a; similarly typedef int* NUMBERPOINTER; NUMBERPOINTER a; Here a is a pointer of integer type.
A typedef is a compiler macro. A reference is a pointer, usually implemented with transparent syntax. They have no relationship between each other.
What is the difference between a micro processor and a macro processor?
Difference between micro and macro marketing
Calling a macro loads the macro into memory, while executing the macro runs the macro.
Macro is big micro is small.
Macro is big micro is little
mirco= small macro= large
macro is bigger than micro
The difference between macro and micro decomposers is micro decomposers can't be seen by the naked eye while macro decomposers are big enough so they can be seen.
#define is a preprocessor directive used to declare macros. typedef is a C++ keyword to define a data type.
Ask Stephen short...he knows all ;)

The same as the difference between huoses and oranges. Did you mean "macro" instead of "marco"?

On SLRs, macro lenses are specially corrected for extreme close-up work. Nikon brand macro lenses bear the name 'Micro', so there is really not much difference.
A macro is simply a text-substitution mechanism. You use the #define directive to define both macro symbols and precompiler directives. Every occurrence of a macro symbol within your code is substituted with the macro definition during preprocessing.
Macro refers to something large in scale, scope or capability; micro, is the opposite, and refers to something small
