How to initialize an unsigned long long type?

Question

I'm trying to initialize an unsigned long long int type. But the compiler is throwing an error

"error: integer constant is too large for "long" type ".

The initialization is shown below :

unsigned long long temp = 1298307964911120440;

Can anybody please let me know what the problem is and suggest a solution for the same.

Answer 1

First, be sure your compiler supports the long long type. Second, add a "ULL" suffix to the number.

Answer 2

Try suffixing your literal value with ULL
