Question 8: Why binary search algorithm is more efficient than the linear search algorithm?

Answer:

Binary search algorithm is more efficient than liner algorithm because the arrays are sorted in asending or desending order and we use "devide and conqrer" technique. In binary search each iteration reduces the search by the factor of two but in the linear we have the same number of searches as we have the number of elements.e.g,if we have array of 1000 elements the linear search will take 1000 iterations however binary search will take max 10.

Question 10: Why the first parameter of operator function for << operator must be passed by reference?

Answer:

Operator<<'s first parameter must be an ostream passed by reference. Its second parameter, the IntList that is printed, does not have to be passed as a const-reference parameter; however it is more efficient to pass it by reference than by value (since that avoids a call to the copy constructor), and it should not be modified by operator<<, so it should be a const reference parameter
