Question

Write a C PROGRAM that will simulate rolling a die.
When rolling a die, one will get a die face value of 1-6. We can use rand function and math ceiling
function to get a random number of 1-6 generated. The program will simulating rolling 5 dice
simultaneously and store their face values into an array of size 5. The program will keep rolling the dice
and print the following:
1. All face values in one line
2. If any three of the dice have the same value, then add one more print line:
****** THREE OF A KIND *******
3. Print the total count need to get “three of a kind” result.

The program then will reset the count to 0 and start over to simulate the following:
1. All face values in one line
2. If the outcome is three and two, then add one more print line:
****** FULL HOUSE *******
3. Print the total count need to get “full house” result.

The program then will reset the count to 0 and start over to simulate the following:
1. All face values in one line
2. If the outcome is a straight line, then add one more print line:
****** STRAIGHT LINE *******
3. Print the total count need to get “straight line” result.

Requirements:
You will need the following functions:
1. Roll5Die function which will generate 5 random die face value and store them into an array of
size 5
2. getThreeKind function which will roll the 5-die continuously until the result is a “Three of a
Kind”. The function then will return the count to main function.
3. getFullHouse function which will roll the 5-die continuously until the result is a “full house”. The
function then will return the count to main function.
4. getStraightLine function which will roll the 5-die continuously until the result is a “straight line”.
The function then will return the count to main function.
5. All print statement should be done in the main() function. The array of 5 die is declared in main()
function. Then the function just make 3 calls and print the result after each call.

Run it on your PC, as the output tends to get very large, I can't post it here
