basic data types

[Paras Sharma]

Hi
Does compiler generates classes for basic data types also ?? or it is
just same as calling malloc
What is the difference bwt 1) ^ 2) ..

1 )
char * c = new char ( 4 ) ;
delete c ;

2 )
char * c = new char [ 4 ] ;
delete [] c ;

Can we use delete [] c in first examples .

thanks
Paras

I think you mean does the compiler initialise built in types when calling
new. The answer is maybe. In your example 1 below, the allocated char is
initialised, in your example 2 the allocates chars are not inituialised.

1 )
char * c = new char ( 4 ) ;
delete c ;
This creates a single char and initialises it with the value 4

2 )
char * c = new char [ 4 ] ;
delete [] c ;

This creates 4 uninitialised chars.

No.
