Count Equal Elements in an Array

Write a function template countMatches(const T values[], int size, T target) that returns, as an int, how many of the first size elements are equal to target.

Because the array elements and target share the type parameter T, both arguments must agree: with an array of std::string, the target has to be a std::string too, not a bare "cow" literal. The tests print one count per line for: an int array {3, 7, 3, 3, 9} with target 3; a char array {'a', 'b', 'a'} with target 'a'; a std::string array {"cat", "dog"} with target "cow"; and the int array again with a size of 0.

Do NOT write a main function.
