long long problem

[wolverine]

Hi,
I compiled the following code

int main()
{
long long a = 0x7ff0000000000000L;
}


I got error "test.cpp:3: error: integer constant is too large for
"long" type". But i think that a long long variable can hold upto
(2^63-1) which is greater that 0x7ff0000000000000. Then why is the
error coming. The error comes only in g++ compiler and not in visual
studio. Could any one help me in this ?


Thanks in advance
Kiran.

int main()

{
long long a = 0x7ff0000000000000L;

}

I got error "test.cpp:3: error: integer constant is too large for
"long" type".

what you need is - long long a=0x7ff0000000000000LL;
see http://www-ccs.ucsd.edu/c/syntax.html#integer constant for more.

and btw - "ISO C++ does not support `long long'".
dont count on that "LL" suffix to work everywhere.
