Unsigned Int Range

P: 1
Hi All,

i have assigned some large positive int value (32 bit length) X to unsigned int variable and due to the range constraints that variable stores the same positive value X in negative representation say Y (where Y<0).

Now my question is If Y = -1018059492 what would be the value of X? And how to do this converision?

Thanks in advance!

Use pointers, you can pointer and unsigned int pointer at an in variable and thus access the data there with no conversion (of course this may not be a valid thing to do for all variable types but it works for and like sized integer type)

int y = -2;
unsigned int *x = (unsigned int *)&y;

printf("%d is equivilent to %u\n", y, *x);


I've leave you to run it over your specific number.
