Answer / prakruthi
new automatically calls the constructor while malloc()
dosen't., also new being an operator, it can be overloaded.
since malloc returns a void pointer it is necessary to
explicitly typecast it into an appropriate type of pointer.
This gets completely avoided when we are using new operator.

Answer / pushpankar mishra
malloc need type casting where as the new operator does not
require this incase if it is character type then char* is
needed in malloc where as for new we do not need this

Answer / sanish joseph
both malloc and new functions are used for dynamic memory
allocations and the basic difference is: malloc requires a
special "typecasting" when it allocates memory for eg. if
the pointer used is the char pointer then after the
processor allocates memory then this allocated memory needs
to be typecasted to char pointer i.e (char*).but new does
not requires any typecasting. Also, free is the keyword used
to free the memory while using malloc and delete the keyword
to free memory while using new, otherwise this will lead the
memory leak.

Answer / cl
The difference is the invocation of constructor: malloc
does not do it.

Answer / swati
In case of Malloc we need to specify the size of memory for
our data types. But in case of New we do not need to specify
the size.
