Write a C$++$ program to read in a multi$-$digit hex number $($as a string$)$ and print it as a decimal number. Make sure you prompt the user for input and title the output. Use a function that converts a hex number to its decimal equivalent.

Decisions to make at program design time:

Will I limit the number of characters?

Will I accept both upper$-$case and lower$-$case characters as input?

Don't forget to follow the Class Coding Principles, and the academic honesty guidelines in the syllabus.
