HW15
Using the example of the interpreter from class (see the Compiler Basics lecture) as a
starting point, write an interpreter in C that can compute the value of
expressions like 9/2, 2^7, and
3+4, for single arithmetic expressions on single digits
using the operators + for addition, - for
subtraction, * for multiplication, / for
division, % for modulo, and ^ for
exponentiation.
