WebJan 20, 2011 · Granted, you must be 100% sure that you're dealing with a negative number: t1 = t1 < 0 ? -1*t1 : t1; I'd assume that's all that abs family does in this scenario. Alternatively, you can subtract the negative value from 0: t1 = t1 < 0 ? 0-t1 : t1; Given that, the standard solution is still favorable as it's more likely to be immediately clear.

It is just a representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND performs logical conjunction (shown in the table above) of the bits in each position of a number in its binary form. &. WebIt’s a standard library having many inbuilt functions like EXIT_FAILURE, EXIT_SUCCESS, RAND_MAX, NULL, etc. Using these functions we can easily get the required solution.
