PROGRAM IN C TO ILLUETRATE THE USE OF “SRAND” WITH “SWITCH STATEMENT”

//IT IS JUST A GEME OF CHANCES AND I HAVE NAMED IT ” ROLL BABY ROLL…”

//rules are so simple listed below——–

–Roll two dice

•7 or 11 on first throw, player wins

•2, 3, or 12 on first throw, player loses

•4, 5, 6, 8, 9, 10 – value becomes player’s “point”

–Player must roll his point before rolling 7 to win
