Instructions: Write a C++ program that will input from the console screen:

1. A whole number
2. A unit of measurement from the following set: {TB, GB, MB, KB, B}

The program will output the equivalent number of bits.

Allow users to continue to input until they indicate that they want to stop

Notes:

1. A blank space will separate the whole number from the unit of measurement.
2. If the user does not input an appropriate unit of measurement:

1. Output an error message.
2. Allow the user to re-input
3. For this exercise assume that the base is 1024 (not 1000). Kilobyte Reference: https://en.wikipedia.org/wiki/Kilobyte
