In what cases using of a 'template' is a better approach
then using of a 'base class'?

Question Posted / nishikant sahu

Answer Posted / nishikant sahu

You can judge the need of Template and base class based on
following rule of thumb..
When operation(Method) doesn't affect on changing the data
type, use template.for ex when you want to write the stack
class of different data TYPE(int, bool,flaot) PUSH & POP
method doesn't affect on changing the data TYPE so in this
case you have to use TEMPLATE instead of Inheritance.
When operation(Method) does affect on changing the data
type, use Inheritance(base class).
