void main(){    print("Example of Bitwise operators");        var a  = 25;    var b = 20;    var c = 0;        // Bitwise AND Operator    print("a & b = ${a&b}");        // Bitwise OR Operator    print("a | b = ${a|b}");        // Bitwise XOR    print("a ^ b = ${a^b}");        // Complement Operator    print("~a = ${(~a)}");        // Binary left shift Operator    c = a <<2;    print("c<<1= ${c}");        // Binary right shift Operator    c = a >>2;    print("c>>1= ${c}");   }  

Q :

why the results are :

a & b = 16 a | b = 29 a ^ b = 13 ~a = 4294967270 c<<1= 100 c>>1= 6
