C Memory manager keeps track of size of bytes which is allocated. This info is generally kept in the byte location pior to pointer location returned by malloc.

Correct !

Some times, s/w will have it's own wrapper over C memory manager, to store other details as which file/line has called for memory allocation...
These things help in debugging

What if we increment the pointer twice and then call free?? Now the pointer has moved 2 places forward.
How does it still de-allocates the complete memory block??

See C++ FAQ [16.14]

* Over-allocate the array and put n just to the left of the first Fred object.
* Use an associative array with p as the key and n as the value.

This isn't C++ questions. Only dinosaurs use malloc in C++ code.
