I know that it's bit-shifting, but what purpose does it serve and when should one use it? c++ c Share Improve this question WebSep 16, 2011 · Shorter integral types are promoted to an int type for bitshift operations. This has nothing to do with the type to which you assign the result of the shift. On 64-bit machines, your second piece of code would be equally problematic since the int types are usually also 32 bit wide.
