A$0$: Base to Decimal

Learning Outcomes

$-----------------$

$1.**$Explain$**$ the difference between characters and numbers on a computer.

$2.**$Use$**$ an array as a lookup table to check for character equality.

$3.**$Use$**$ an algorithm to translate a number from a different base to decimal.

$4.**$Develop$**$ a program that $**$utilizes$**$ this algorithm.

Specifications

$--------------$

For this assignment you will write a program that can convert numbers written in bases $2$ to $16$ into their decimal equivalents. The numbers will be prefixed with $`0$b$`,`0$q$`,`0$s$`,`0$n$`,`0$z$`$ and $`0$x$`,$ for example, indicting which base the given input is in$.$

There's no need to write any code outside of lines $20-27$ inside $`$main$()`$ and the $`$chars$\_$to$\_$int$()`$ function.
