//A NICE IMPLEMENTATION TO TURN ON A BIT

//A NICE IMPLEMENTATION TO TURN ON A SINGLE BIT IN BYTE OF CHAR//

//kth bit starts from right hand side//

//kth power of 2 will on that periticular bit..

//for eg.0th bit....0000 0001

//for eg.1th bit....0000 0010

//for eg.2th bit....0000 0100

//for eg.3th bit....0000 1000

//for eg.4th bit....0001 0000

//for eg.5th bit....0010 0000

//for eg.6th bit....0100 0000

//for eg.7th bit....1000 0000
