Question

please help with the operator overloading lab (intArray) in c++ will provide what it is being required and the code that was given from the book.

Operator Overloading Lab (IntArray) The array construct in C is very efficient but also very dangerous for the an array of th index 100. Not only is this r example, many novice programmers fall into the trap of declari elements and then try to access an error in C, but the language won't even alert the user when the mistake made. C++ allows programmers to define safer and more flexible array constructs if they are w efficiency. The lling to sacrifice some of C's runtime effi purpose of this lab is to see how this is done and to gain some experience in overloading operators. The heart of this assignment is a class that you will define called IntArra With it, the user will be able to declare integer arrays of any size with automafic 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 and inequality, add two arrays, and output arrays using the overloaded< operator. For example: include <iostream> include "IntArray.h" using namespace std: int main) f IntArray a(10), w(10): IntArray b(-3, 6) IntArray c(6, 8) IntArray d (5, 5); IntArray z; // Ten elements, indexed 0 to 9 // Ten elements, indexed -3 to 6 // Three elements, indexed 6 to8 // Single element array, indexed at 5 // Ten elements, indexed 0 to 9 // hight) and low) return largest and smallest legal indices for (int í a. low ( ); î <" a. high(); ++1) ali]-i10; // Access just like normal array /7 Output array contents. Note that you will overload // the << operator to do this cout << a << endl; // The code for the overloaded << operator will look // something like this: for (int i. a.low ( ) ; î <-a.high ( ); ?++) cout << "al" <i<"-" << alil <" Focus on Object-Oriented Programming with C++ Page 270
