Recursive functions

Hi all,

1)I need your help to solve a problem.
I have a function whose prototype is

int reclen(char *)

This function has to find the length of the string passed to it.But
the conditions are that no local variable or global variable should be
used.I have to use recursive functions.

2)sizeof(int) is 2 bytes in turboC.It is 4 bytes in case of gcc.why
different compilers allocate different amount of memory?what is the
reason behind it?
