  • Question 1
    • What happens when you attempt to compile and run the following code?
       #include <iostream>
       using namespace std;
       template<class A>
       void f(A a)
       {
       cout<<1<<endl;
       }
       void f(int a)
       {
       cout<<2<<endl;
       }
       int main(){
       int a = 1;
       f<float>(a);
       return 0;
       }

      Answer: A
  • Question 2
    • What happens when you attempt to compile and run the following code?
       #include <deque>
       #include <iostream>#include <algorithm>
       #include <functional>
       using namespace std;
       class B { int val;
       public:
       B(int v):val(v){}
       int getV() const {return val;} bool operator > (const B & v) const { return val>v.val;} };
       ostream & operator <<(ostream & out, const B & v) { out<<v.getV(); return out;}
       template<class T>struct Out {
       ostream & out; Out(ostream & o): out(o){}
       void operator() (const T & val ) { out<<val<<" "; } };
       int main() {
       int t[]={20, 30, 10, 20, 30, 10, 20, 30, 10, 20};
       deque<B> d1(t, t+10);
       sort(d1.begin(), d1.end(), greater<B>());
       pair<deque<B> ::iterator, deque<B>::iterator > result = equal_range(d1.begin(), d1.end(),
      B(20), greater<B>());
       for_each(result.first, result.second, Out<B>(cout));cout<<endl;
       return 0;
       }
      Program outputs:

      Answer: B

       void print(T start, T end) {
       while (start != end) {
       std::cout << *start << " "; start++;
       }
       }
       int main()
       {
