C++ PROGRAMMING need easy urgent help please. I've finished all the code but its not quite running correctly. Will attach all instructions and code. All code to be edited is in Text.cpp copied below. Please do not edit anything except Text.cpp and please make sure the code compiles so I can give 5 stars. Thank you <3

Instructions:

- Implement the Text ADT (use the declaration in the Text.h file) (40 points)

- Text(), operator=() and ~Text(), getLength(), clear(), operator[]

- Programming Exercise 2: Implement the functions toUpper() and toLower() and test them by activating LAB1_TEST1 (30 points)

- Programming Exercise 3: Implement the ope

rators ==, <, > and test them by activating LAB1_TEST2 (30 points)

config.h:

/** * Text class (Lab 1) configuration file. * Activate test 'N' by defining the corresponding LAB1_TESTN to have the value 1. */

#define LAB1_TEST1 0 // Programming exercise 2: toUpper and toLower #define LAB1_TEST2 0 // Programming exercise 3: ==, <, and >
