unsigned int command = 4;
cout << command;
command = (command << 1);
cout << command;
command 开发者_开发百科= (command << 1);
cout << command;
Output:
4
8
10
Why is is the output of the last line 10
, and not 16
?
There's probably a cout << hex
somewhere before this code runs. Either that or you accidentally set cout
to format numbers in hexadecimal. If you add:
command = (command<<1);
cout << command;
It should print out 20
in hex mode.
10
is hexadecimal for 16
.
0x10 == 16
Sorry if I am stating the obvious.
