Even without my failure to maintain case in the variable, it would still
return 2 instead of 7 due to premature termination of conditional
expression (semicolon), and due to assignment instead of comparison in
condition (= instead of ==). Amongst folks as careless as myself, those
two seem to be the two most common typos in C programs.
