1st binary value is 1111(f=15)0111(7).
2nd binary value is 1010(A=10)1011(B=11).
The condition is "&" that means "Evaluates to true only if both variables are true either false"
11110111
10101011
--------
10100011 = 163 decimal.
And second condition is "^" That means "Evaluates to true if one variable is true otherwise false"
11110111
10101011
--------
01011100 = 92 decimal.
Ans: 163, 92.

0x is for indicating to the compiler that the no. is in hexadecimal.
A 0 is prefixed to indicate an octal no. .
A 0 is prefixed to indicate an octal no. .

1st binary value is 1111(f=15)0111(7)=247 decimal
2nd binary value is 1010(A=10)1011(B=11)=171 decimal
Add these two numbers you will get the value as (11110111+10101011)=110100010 ie binary value convert into decimal ie (247+171)=418, and
Subtract those two numbers you get the value as (11110111-10101011)=1001100 decimal value is (247-171)=76.
