Instruction: You must use pointers for this lab. No arrays, no structures. For example, if you need an array of floats to hold the scores, do not use float score 15]. Rather use float *score, then use dynamic memory allocation to hold required memory. You must use memory optimally, that is if you have only 6 scores, you must point to a memory chunk of sizeof (float) 6 bytes. Similarly, to hold a name, instead of doing it with 2D char arrays, use 2D pointers (char firstName[15][20] char **firstName). Problem: Write a menu based program to maintain student records. Your program should take the following inputs 1. Student first name (max. 20 characters) 2. Student last name, (max. 20 characters) 3. Student scores (float/double), e.g. 85.4 Your program should be able to take records of a minimum of 5 students. After taking the records you should provide 8 functionalities to the user 1. Print records-prints records of all students 2. Add a new record take a new record from the user for a new student. Be careful, you may need to allocate more memory using dynamic memory allocation 3. Delete record(s)-to delete a record, ask for the last name of the student from the user. If there are multiple students with same last name, you must delete all of their records. You must free up the memory holding these records 4. Search by last name prints record of the student with a given last name. If there are multiple students with the same last name, print records for all of them. 5. Sort by score-sort the records of students according to their scores, and then print thesorted records 6. Sort by last name-sort the records of students according to their names alphabetically, and then print the sorted records Instruction: You must use pointers for this lab. No arrays, no structures.
