The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player's choice of either High or Low is compared to random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered "low". A number between 8 and 13 inclusive is "high". The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to: High Low Gane RULES 1 through 6_are lou Nunbers 8 through 13 are high Number ? is neither high or low You have 1000 points. Enter points to risk: 500 Predict (1=High, 0=Low): 0 Nunber is 4 You win.
