You must use  ld to print a long int  and  lld to print a long long int   Note that only long long int is guaranteed to be large enough to store the result of that calculation  or  indeed  the input values you re using    You will also need to ensure that you use your compiler in a C99-compatible mode  for example  using the -std gnu99 option to gcc    This is because the long long int type was not introduced until C99  and although many compilers implement long long int in C90 mode as an extension  the constant 2147483648 may have a type of unsigned int or unsigned long in C90   If this is the case in your implementation  then the value of -2147483648 will also have unsigned type and will therefore be positive  and the overall result will be not what you expect
