This is an interesting question on advanced macro usage.

#define power(a) #a

>> The # stringifies the macro token i.e. power(432) => "432".


>> This is like converting '4' into its ascii value i.e. 52.

actually #a in macro will be expanded as "a" in the main program.power(432) means tat "432".now u should take this as an single dimensional array then *("432") will point to the first location in the string ,so ascii value if 4 is printed as ... 52
