Answer 1

What do you mean by "right value of bit"?

Answer 2

The number 21 in my program should be 8 in output

Answer 3

Use sizeof operator to get size of a certain type (in bytes), and then multiply it by 8 (the number of bits per byte) to get the number of bits for the respective data type.

Console.WriteLine( sizeof( int ) ); // in bytes

Console.WriteLine( sizeof( int ) * 8 ); // in bits
