WHAT IS PRE POSSESSORS?

Answer Posted / ravikanth

The preprocessor is used to modify your program according to
the preprocessor directives in your source code.

Preprocessor directives (such as #define) give the
preprocessor specific instructions on how to modify your
source code. The preprocessor reads in all of your include
files and the source code you are compiling and creates a
preprocessed version of your source code.

Given only putchar (no sprintf, itoa, etc.) write a routine putlong that prints out an unsigned long in decimal.

The interviewer wasn't too pleased and asked me to give a solution which didn't need the array ].
