What is the difference between `new` and `new()` for a struct in C/C++? -

possible duplicate:
do parentheses after type name make difference new?

in code, saw struct this:

typedef struct mystruct {     int numberone;     int numbertwo; } mystruct;

later, tried instantiating 1 of these structs using

mystruct *pstruct = new mystruct();

which worked fine visual studio 2010, failed obscure linker error on different compiler. took while until found out omitting braces this

mystruct *pstruct = new mystruct;

solved issue.

so, difference between these 2 invocations , 1 right 1 use?

new mystruct performs default initialization, in case nothing.

new mystruct() performs value initialization, in case sets both int variables zero.
