PLEASE ANSWER THE 3 QUESTIONS CORRECTLY

1) Consider this prototype for a template function:

template <class Item>

void foo(Item x);

Which is the right way to call the foo function with an integer argument named i?

      
A) int i = 5;

foo( i );

B) foo<Item>( i );

      
C) foo(<int> i );

      
D) int i = 5;

foo<int>( i );

2) The std::binary_search function will test if a value exists in sorted sequence. It returns true if any element in the range [first,last] is equivalent to that value, and false otherwise.

A) True

B) False

3) Consider the following graph:

In what order are the vertices visited for a depth-first search that starts at v0?

      
A) 0, 4, 1, 6
