Write the following C++ functions for a memory module. o A void function named Initialize() that takes a fstream reference parameter and an int parameter named ram. It rewrites the file referenced by ram with 100 rows of 32-character strings of zero. o A string function named Read () that takes a fstream reference parameter and an int parameter named ram and addr respectively. If addr is between 0 and 99 inclusively, the function returns the line of the file referenced by ram whose value equals addr; otherwise, it returns an empty string. The first line starts from 0. o A void function named Write() that takes a fstream reference parameter, a string parameter and an int parameter named ram, data and addr. If addr is between 0 and 99 inclusively, the function writes data on the line equal to addr of the file referenced by ram; otherwise, it does nothing.
