Write a function template that will act like the generic algorithm count, which

returns how many times a specified item occurs in a half$-$open range.

For example, given the definition:

int arr$[]=\{2,5,2,4,5,2,6,2\}$;

The following code

count$($arr$,$ arr$+8,2)$

would return the value $4$ because there are four $2\text{'}$s in the range. Because you are writing a

function template, your code will also work for an STL list of Students or vector of Dogs...
