I get runtime error for the above code .
Any specific reason ?

The error has been explained but this can easily be picked up by your
compiler. Adjust the warning levels for it.

That depends on the compiler. gcc, for example, can diagnose
mismatches between a printf format string and arguments (if the format
is given as a string literal), but I don't know whether other
compilers can do so.

The bottom line is that it's entirely up to you, the programmer, to
make sure that your format string is correct for the argument types
you're feeding it. Some compilers might be able to help you diagnose
the problem, but you can't count on it. The only reliable solution is
to get it right in the first place.
