why did bhaiya write
template<class forwarditerator, class T >
before the function search() in the example of iterator?
please explain in detail what exactly the above code is doing.
Iterators example
he is making template
function
template functions are used when u need to change the datatype of variable at different point in times
For example, a software company may need sort() for different data types. Rather than writing and maintaining the multiple codes, we can write one sort() and pass data type as a parameter.
