&&,||,! are only 3 logical operators but &,|,^,>>,<<,~ are only 6 bitwise operators.

I agree @Linu.

'&' is a bitwise operator. '!' is unary operator. Both are not logical operator then why we choose only '&'.

The & operator is a bitwise operator.

Hai @Vinoth. Difference is that in logical && AND operator we have the comparison of two nonzero or zero or either both combination according to the truth table of AND.

But in bitwise operator.

For ex: 10&5 write it in binary format.
1010
+
0101
-----
1010
-----

The answer is 10 for bitwise. But for logical and the value is 1 because both are non zero numbers.

When we are working on bitwise operator it will manipulate the data direct on binary representation.

@Tata p.

Put like this a>=5?(b=100):(c=100);

Bitwise operators are &,|,^
Logical operators are logical and (&&),logical or(||)
so & is not logical operator

Can anyone tell me why it is giving lvalue required
a>=5?b=100:c=200
