Detailed explanation of C bit operations

numbers 84, I .e. 01010100 (2) from the left, the numbers 3, 4, 5, 7, and 8 are as follows:01010100 (2) 00111011 (2)00010000 (2)That is, a = 84, B = 59C = A B = 16C language source code:# Include Main (){Int A = 84;Int B = 59;Printf ("% d", A B );} 2. "bitwise OR" Operator (|)If one of the two binary bits is 1, The result value of this bits is 1. In logic or operations, it is true. .For example, 60 (8) | 17 (8), bitwise OR operation is performed on October 60 and October 17.00110000| 00001111
