A strange phenomenon, an operations-CodePudding

 
Int a=4 b=14; 
Int c=a + b & lt; <4. 
Console. WriteLine (" c="+ c); 
Console. WriteLine (0 XFF & amp; 228); 
Console. WriteLine (0 XFF & amp; C); 
C=228; 
Console. WriteLine (0 XFF & amp; C); 
The Console. ReadLine ();

Use an operation to get an integer c, its value is 228, if with the run with 0 XFF to 32
But if the 228 directly to the assigned to c, and 0 XFF and run again, you'll get 228

You want to ask what's the difference between them

CodePudding user response:

C is 288, not 228288 & amp; 0 XFF is 32

CodePudding user response:

0 XFF here convert into (~ 0), taking in the results, will be clear at a glance,
