Operator Overloading Lab (IntArray) The array construct in C is very efficient but also very dangerous for the unwary For example, many novice programmers fall into the trap of declaring an array of 100 elements and then try to access the element with index 100. Not only is thie an error in C, but the language won't even alert the user when the mistake is made. C++ allows programmers to define safer and more flexible array constructs if they are willing to sacrifice some of C's runtime efficiency. The purpose of this lab is to see how this is done and to gain some experience in overloading operators called IntArray rray With it, the user will be able to declare integer arrays of any size with automatic range checking of indices. The upper and lower indices can be any integer positive or negative, rather than the fixed limits of o to SIZE-1. It will also be possible to assign entire arrays to each other, compare two arrays for equal and inequality, add two arrays, and output arrays using the overloaded ity operator. For example: tinclude ciostream> include "IntArray.h" using namespace std; int main) f // Ten elements, indexed 0 to 9 // Ten elements, indexed -3 to 6 // Three elements, indexed 6 to 8 // Single element array, indexed at 5 // Ten elements, indexed 0 to 9 IntArray a (10), w(10) IntArray b(-3, 6) IntArray c(6, 8) IntArray d(5, 5); IntArray zi // high() and low() return largest and smallest legal indices for (int i =a.Iow(); iExplanation / Answer
