what is memory leak?

Answer / roshan.p.r.
Consider the following example..
int *p=new int[10];
here ten bytes of memory is allocated and the address is
stored in p. the only way to access this memory is via p.
now suppose if u allocate a new memory to p like
p=new int[20];
the previous address(10 bytes is lost we cant access it
again)because the only way that we had to access it was
pointer p and now a new address(20 bytes) is stored in p.
So we say there is a memory leak.
the best way to handle this is.
int *p=new int[10];
[]delete p;
p=0;
p=new int[20];
so in the above case we have first released the memory
pointed by p with delete function and then a new address is
assigned to it.

Memory leak is nothing but u create huge chunk of memory
with a malloc or any such mechanism and u never free that
manually which make the available free main memory in the
system to minimum. this may even lead to system crashing.
