In this exercise, you will be writing a C++ program that defines a custom string class. You will write the program into separate files. You are provided with a starter code containing a class named CustomString consisting of an attribute of type string, named data, several methods, and operators. The class declaration has already been given fully in the specification file, custom_string.hpp. Your job in this exercise, is to complete the class implementation. The main file, main.cpp has also been given fully. The purpose of the main file is to perform automatic testing on the tasks you have accomplished. When you run the program with the original codebase, you should notice that all tests FAIL (as shown in Figure 1). Your job is to turn the tests to "PASS" (like in Figure 2) by accomplishing the tasks in this exercise. Testing Task 1: Mutator methods FAIL FAIL FAIL FAIL FAIL FAIL FAIL FAIL 1(a). Testing pushFront (). It should add the string in front. 1(b). Testing pushBack(). It should add string at the back 1(c)-i. Testing pop(). It should return the extracted string. 1(c)-ii. Testing pop(). The extracted string should be erased from the attribute accordingly. 1(d)-i. Testing popFront (). It should return the extracted string. 1(d)-ii. Testing popFront (). The extracted string should be erased from the attribute accordingly. 1(e)-i. Testing popBack (). It should return the extracted string. 1(e)-ii. Testing popBack(). The extracted string should be erased from the attribute accordingly. Testing Task 2: Overloaded operators FAIL 2(a). Testing operator!. It should return a CustomString with reversed data. FAIL 2(b). Testing operator*. It should return a CustomString with repeated string. Testing Task 3: Conversion methods FAIL 3(a). Testing toDouble(). It should return the corresponding value of type double FAIL 3(b). Testing toupper(). It should return a CustomString with upper case string Testing Summary: Number of Test: 12 Number of Pass: 0 Number of Fail: 12 Pass Rate : 0%
