Write and test a function char *Concatenate(char *s1, char
*s2) that takes two strings and returns a new string that is
the concatenation of them. The function should allocate the memory
for storing the new string with malloc.
Write a program to see how much memory you can allocate before
the computer runs out of space. malloc returns NULL when it cannot
allocate the number of bytes requested, so one way to do this is to
count how many blocks of 1000 bytes can be allocated before
malloc returns NULL.
What's wrong with this program? What happens when you compile
and run it? (It will give you warning, but can still run the
program)?
