Question
Here we have the classic race between the tortoise and the hare. For this project, you be using random-number generation to move the creatures. To make things more interesting, the animals have to race up the side of a slippery mountain, which could cause them to lose ground. In this race either animal could win or there could be a tie with no clear winner.
The animals begin at "Square 1" of 70 squares. Each of the squares represents a position the animal can hold along the racetrack. The finish line is at Square 70. When an animal wins, a winning message of your choice should be posted. For example:
Yay! The rabbit won! He hops the fastest!
Woo-hooo! Slow and steady wins the race! Congratulations, turtle!
Tie score--no winner! Want to race again?
To start the race, print a message similar to:
Bang! Off they go!
There is a clock that ticks once per second. With each tick of the clock, your program should adjust the position of the animals according to the following rules:
Animal Move Type Percentage of the Time Actual Move
Tortoise Fast Plod 50% 3 squares to the right
Tortoise Slip 20% 6 squares to the left
Tortoise Slow Plod 30% 1 squares to the right
Hare Sleep 20% No move at all
Hare Big Hop 20% 9 squares to the right
Hare Big Slip 10% 12 squares to the left
Hare Small Hop 30% 1 square to the right
Hare Small Slip 20% 2 squares to the left
Keep track of the positions of the animals by using variables. If an animal slips, the lowest it can go is back to position 1. The highest it can go is to position 70 when it wins the race.
You will work with the percentages in the table above by generating a random integer current in the range
1 current 10.
For the tortoise, a "fast plod" is when 1 current 5, a "slip" when 6 current 7, or a "slow plod" 8 current 10. A similar approach would be used to set up the moves for the hare.
For each tick of the clock (each repetition of the loop), print a 70-position line showing the letter T in the tortoise’s position and the letter H in the hare’s position. If the two animals land on the same square, which may happen, the animals will bump. If this happens, print BUMP! at the current position.
After you print each line, check to see if either animal has landed on Square 70. If this happens, print a winning-type message.
It may make the simulation more interesting if you have users press any key after each iteration of the loop, so that they can see the movement of the animals.

positions(&hare, &tortoise);//to call the postions functions so they print out the positions like a real race
count++;//see how many times the loop runs
}while(hare <70 && tortoise <70 );
