Hi, i'm trying to use a long long integer to store a number, but when i run the compiled code i get a negative number. any help?
Code:#include <stdio.h> void main() { long long num1; num1=600851475143; printf("\n%d\n", num1); }
Just began programming and having trouble with integers

Use unsigned long long. Also, use the correct format flag for printf.
It is too clear and so it is hard to see.
A dunce once searched for fire with a lighted lantern.
Had he known what fire was,
He could have cooked his rice much sooner.
can you give me a list of C format flags? i never learned them
In that case add the "ll" suffix to that number, as it tells the compiler to store it using 64 bits.
Code:num1=600851475143ll;
adding the "ll" still returns a minus. using an unsigned long long doesn't work either. Any code examples? Thanks
I'd be %llu, and using unsigned long long together.

Thank you, so I was just using the wrong format flag. I am also using a signed variable, thanks. Problem solved. Now to figure out this Euler problem...
Well that's easy... Click Here!Originally Posted by sfkc1588
