You are to write a numerical base converter. This application will present the
user with a menu to select the originating base and a subsequent menu to select
the destination base. You will loop through these menus until the user wishes to
quit.
You are required to break the code into logical functions (eg. a function that
converts to hexadecimal, another function to convert to binary, etc.).
Notes
• The code for this assignment will be more rigorously graded than for
assignment #1.
• You will need arrays to validate the input. You may choose to use arrays
to display the output – but it is not necessary.
• The atoi() C function is very useful for this assignment. Investigate it.
• It is recommended to take the numbers in as a string, validate each
character based on the base required (e.g. 3G4 is not a valid hexadecimal
value, nor is 21 a valid binary).
• Based on what happened in assignment #1, start early and ask
questions.
• Refer to the submission standards.
Sample Output:
Please select a base to start:
1) Decimal
2) Hexidecimal
3) Binary
Selection: 3
Please enter a value: 2
That is invalid, please enter a value: 101
Please select a base to convert to:
1) Decimal
2) Hexidecimal
3) Binary
Selection: 1
Binary 101 converts to Decimal 5.
