After, notX = !x, what we want to achieve is: if notX is 0x0, return y, if notX is 0x1, return z. Let t = ~notX + 1, if x is true, t = 0x0; if x is false, t = 0xFFFFFFFF. Thus ~t & y will return y if x is true; return 0x0 if x is false. t & z will return 0x0 if x is true; return z if x is false. reagan airport hotels shuttleWebThis will create a subdirectory of the current directory having the same name as the current directory where the files from the tar file are placed.
