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.

128 64 32 16 8 4 2 1.
1 0 1 0 0 0 1 1 => 128+32+2+1 = 163.
1 0 1 0 0 0 1 1 => 128+32+2+1 = 163.

@Swethasai I'm giving clarification for your doubt.
Here 10100011 convert into decimal number 128+0+32+0+0+0+2+1 = 163.
Here 10100011 convert into decimal number 128+0+32+0+0+0+2+1 = 163.

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.
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.

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.
Like 10101100.
10011001.
Answer = 10111101.
