Long long type

[hqt]

I'm using Code::Block. I have this line of code:

define maxC 9000000000; //9.10^10
int main(){
     long long min=maxC;
}

I think 9.10^10 doesn't exceed long long type. But, I don't know, when I'm compile this problem, there's a warning:
<warning: integer constant is too large for 'long' type>
Because, long type is just about 4.10^10 for unsign and 2.10^10 for sign integer. So, I cannot use it.

So, how can I use long long type, and no above warning, please help me, please. (I think, they warning, mean sometimes, they will go wrong !!!)

thanks

First you should not have the semicolon at the end of your define. Second what compiler are you using?

I think 9.10^10 doesn't exceed long long type. But, I don't know, when I'm compile this problem, there's a warning:

If you need to know the size of the variables a type can hold on your system you should look at the functions in the limits include file:

#include <iostream>
#include <limits>

int main(){
   std::cout << "Maximum value for long:      " << std::numeric_limits<long>::max() << std::endl;
   std::cout << "Maximum value for long long: " << std::numeric_limits<long long>::max() << std::endl;
}

Put a LL for long long suffix at the integer.
9000000000LL

>>define maxC 9000000000; //9.10^10
const long long MaxC = 9000000000LL;

static const long long MaxC = 9000000000LL;

EDIT:
It's ok, I just read that static is not necessary...
