Please help me with this entire C++ lab example. I know it looks long but i promise most of it are just explanations. I will provide the given codes below the pictured instructions. thank you so much

e inheritance Lab (String Class) One of the most popular classes to define in C++ is the one that emulate string literal in C. The reason is that a string is not a built-in type in C used all the time. Thus, to perform the various manipulations o must call upon functions in the library string.h that perform copy, duplicate, compare, etc. In Ctt, this need is obviated by tsuch as function and operator overloading. In order to represent the state of a object, you will use two data members in and yet it is rations such as use of the length, length, of the string as an int a pointer, buf, to the string literal of type char* A pointer to a character (char*) is used instead of a fixed-length character array so that memory can be allocated at run-time (via the operator new) and, therefore, have no restrictions placed upon the length of the string (too big or too small). The length field is not strictly mandatory since it can always be obtained from the string pointer via the strlen () idea to have it to avoid repeated calls to strlen ( ) . function. However, its probably a good Overloaded Constructor Functions The creation of each String instance involves allocation of space on the heap, copying the string literal, and setting the length data member accordingly Because there are many different ways in which a String object can be initialized, the constructor functions for the String class must be overloaded to accommodate all of the various situations. First, if a String object is created with no explicit initialization, then the default constructor (the one that can be called with no actual arguments) will be called. t makes sense that we should have the invoking instance point to an empty string literal whose length is zero.
