I have one doubt.
What does below statement mean?
#define sizeof(operator)
where operator can be int or float etc.
Does this statement meaningful and where it can be used?

The following define overrides all the occurrences of sizeof and replaces by blank, there is no definition of sizeof on the right hand side of expression
#define sizeof(operator)
example
printf("val = %d", sizeof(int)); is made to look like
printf("val = %d", ); // replaced by blank, int not processed
// causes compilation error

Single Attempt in the sense... It must first print "Hello" and it Must go to else part and print "World"..... No loops, Recursion are allowed........................
