Sorry, that is not strictly correct. According to the man page:

"The alloca() function allocates size bytes of space in the
stack frame of the caller, and returns a pointer to the
allocated block. This temporary space is automatically freed
when the caller returns."

Now this is the real reason:
" If the allocated block is beyond the current stack limit,
the resulting behavior is undefined."

Answer / sathish kumar

Hi All,

If you use alloca inside a function when it retuns from
function it will be resulting in memory leak. Thats why
its discouraged to use.

Thanks & Regards

Write a function stroverlap that takes (at least) two strings, and concatenates them, but does not duplicate any overlap. You only need to worry about overlaps between the end of the first string and the beginning of the second string. Examples: batman, manonthemoon = batmanonthemoon batmmamaman, mamamanonthemoon = batmmamamanonthemoon bat, man = batman batman, batman = batman batman, menonthemoon = batmanmenonthemoon
