Decimal, Octal & Hexadecimal
Hi all.
Can anyone help me clarify these statements.
1. C support unary minus operator for hexadecimal and octal literals (eg. -0xFF, -002)
2. Negative hexadecimal will count from FFFFFFFF for 'int' type.?
3. Negative octal will count from 377777777777 for 'int' type. ?
Am I right?
I just try this out.
Code:#include <stdio.h> int main() { int x = -1; printf("%i %o %x\n", x, x, x); int y = -0x01; printf("%i %o %x\n", y, y, y); int z = -001; printf("%i %o %x\n", z, z, z); return 0; } /* Output : 1 377777777777 FFFFFFFF 1 377777777777 FFFFFFFF 1 377777777777 FFFFFFFF */
Lastly, how to print hexadecimal and octal as '-0x01' and '-001' instead of 'FFFFFFFF' and '377777777777' using printf?
Regards,
mie.
