Answer: Templates allow to create generic functions that admit any data type as parameters and return value without having to overload the function with all the possible data types. Until certain point they fulfill the functionality of a macro. Its prototype is any of the two following ones: <br /> <p>template identifier> function_declaration; template identifier> <br /> function_declaration;</p><br /> <p>The only difference between both prototypes is the use of keyword class or <br /> typename, its use is indistinct since both expressions have exactly the same <br /> meaning and behave exactly the same way. </p>
