Write the definitions of the member functions of the class integerManipulation not given in Example 10-11. Also add the following operations to this class: (1) Split the number into blocks of n-digit numbers starting from right to left and find the sum of these n-digit numbers. (Note that the last block may not have n digits. If needed add additional instance variables.) (2) Determine whether the number is prime. (3) Find the prime factorization of the number.
