unsigned *inc_3(unsigned x);
unsigned *dec_3(unsigned x);
unsigned *negate_3(unsigned x);
unsigned *abs_3(unsigned x);
DESCRIPTIONinc_3 increments x by one. Equivalent to ++x.
dec_3 decrements x by one. Equivalent to --x.
negate_3 negates x. Equivalent to x=-x.
abs_3 takes the absolute value of x. Equivalent to x=x<0?-x:x.
RETURN VALUEinc_3, dec_3, negate_3 and abs_3 all return a pointer to x which has been updated in place.
EXAMPLESSome unary arithmetic operations on triple-ints:
unsigned x; assign_int_3(x, 44); negate_3(x); /* x is now -44 */ inc_3(x); /* x is now -43 */ abs_3(x); /* x is now 43 */ dec_3(x); /* x is now 42 */
