What is difference between template and macro??

[chinmay.sahoo]

There is no way for the compiler to verify that the macro parameters are of compatible types. The macro is expanded without any special type checking.

If macro parameter has a postincremented variable ( like c++ ), the increment is performed two times.

Because macros are expanded by the preprocessor, compiler error messages will refer to the expanded macro, rather than the macro definition itself. Also, the macro will show up in expanded form during debugging.

for example:
Macro:

#define min(i, j) (i < j ? i : j)
template: template<class T> T min (T i, T j) { return i < j ? i : j; }

what is template?

 

[adilkhan]

In C++ there is a major difference between a template and a macro. A
macro is merely a string that the compiler replaces with the value that
was defined. E.g.
#define STRING_TO_BE_REPLACED "ValueToReplaceWith"

A template is a way to make functions independent of data-types. This
cannot be accomplished using macros. E.g. a sorting function doesn't
have to care whether it's sorting integers or letters since the same
algorithm might apply anyway.
