b1 = 1111(F) 0111(7) = OxF7
b2 = 1010(A) 1011(B) = OxAB
-----------------------
b1 & b2 = 1010 0011

b1 & b2 = 163


==========================================

b1 = 1111(F) 0111(7) = OxF7
b2 = 1010(A) 1011(B) = OxAB
-----------------------
b1 ^ b2 = 0101 1100

|||| |||----- = 1*0 = 0
|||| ||------ = 2*0 = 0

b1 ^ b2 = 92

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.

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.

For simple calculations use these code for fast conversion for decimal to binary and binary to desired values "8421".

Hexadecimal values 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A = 10, B = 11, C = 12, D = 13, E = 14, F = 15.
A =10
So, we take 8 4 2 1
=> 1 0 1 0 = 8 + 2 = 10.

F = 15
So, we take 8 4 2 1
=> 1 1 1 1= 8 + 4 + 2 + 1 = 15.

(0xF7)its in hexadecimal lang convert it into binary then value is 11110111 similarly (0xAB)value is 10101011.

Add these two numbers you will get the value as 10100011 ie binary value convert into decimal ie 163, and

Subtract those two numbers you get the value as 01011100 decimal value is 92.

I have one doubt in or ^ operator because or operator explain that if both value are true than answer should be true or infect one value are also true than answer will true.

Like 10101100.

10011001.

Answer = 10111101.

OR operator

how it is possible ?
11110111
10101011
_________
01011100 = 92

OR operator
1 1 T
1 0 T
0 1 T
0 0 F

Here is the total procedure to compute the value.

1 0 1 0 0 0 1 1.

2^7*1 2^6*0 2^5*1 2^4*0 2^3*0 2^2*0 2^1*1 2^0*1.

128+0+32+0+0+0+2+1 = 163.

Excuse me I have one doubt in above explanation how come 10100011 is equal to 163 can anybody explain I am not able to understand.

@Swethasai I'm giving clarification for your doubt.

Here 10100011 convert into decimal number 128+0+32+0+0+0+2+1 = 163.
