I just need the code structure at the end of the document. Nothing else.


SIT102 – Introduction to Programming Answers for 6.2P Working With Vectors Student Name: Eiman Student ID: 5000834 Question 1: Summarise in your own words what the difference is between a standard array and a dynamic array (such as a vector). The main difference between a dynamic array and a regular array is the size. In a regular array the sized is fixed from compilation. In closing the size of an array you can't change it again just think of it set in stone. A dynamic array is basically an array that grow and shrink on demand during run time. Question 2: How can we add elements to a vector in C++? - what is the procedure we call to increase the size of the vector? The C++ function std::vector::resize() changes the size of vector. If n is smaller than current size then extra elements are destroyed. If n is greater than current container size then new elements are inserted at the end of vector. If val is specified then new elements are initialled with val. Question 3: How can you remove the last element from a vector, thereby reducing the size of the vector? clear() removes all elements from vector and reducing it to size 0. erase() is used to remove specific elements from vector. Question 4: Briefly explain why we would want to use pass-by-reference when working with a vector instead of pass-by-value. In pass by reference, no new copy of the variable is made, so overhead of copying is saved. This makes programs efficient especially when passing objects of large structs or classes.
