Question

1. Write a program that plays a simple dice game between the computer and the user. When the program runs, it asks the user to input an even number in the interval [2..12], the number of plays. Display a prompt and read the input into a variable called ‘plays’ using input validation. Your code must ensure that the input always ends up being valid, i.e. even and in [2..12].
2. A loop then repeats for ‘plays’ iterations. Do the following for each iteration:
 generate a random integer in the range of 1 through 6; this is the face value of the
computer’s die; output it clearly labeled as ‘computer’s die’
 generate another random integer in the range of 1 through 6; this is the face value of
the user’s die; output it clearly labeled as ‘user’s die’
 the die with the highest value wins; display the winner for this iteration, computer or
user, or state it was a tie
3. As the loop iterates, the program keeps count of the number of times the computer wins, and of the number of times that the user wins. After the loop performs all of its iterations, the program displays the grand winner, the computer or the user, or it states that the game was tied.

Answer 1

Code (in C):

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
srand(time(0));
int plays,i,cw=0,uw=0;
printf("Input an even number in the interval [2..12], the number of plays: ");
scanf("%d",&plays);
while(!(plays%2==0 && plays>=2 &&plays<=12))
{
printf("Try again!\n");
printf("Input an even number in the interval [2..12], the number of plays: ");
scanf("%d",&plays);
}
for(i=0;i<plays;i++)
{
int cd = (rand() % (6 - 1 + 1)) + 1;
printf("\nComputer’s Die: %d\n",cd);
int ud = (rand() % (6 - 1 + 1)) + 1;
printf("User’s Die: %d\n",ud);
if(cd>ud)
{
printf("Winner -> Computer\n");
cw++;
}
else if(ud>cd)
{
printf("Winner -> User\n");
uw++;
}
else
printf("Tie\n");
}
if(cw>uw)
printf("\nGrand winner -> Computer\n");
else if(cw<uw)
printf("\nGrand winner -> User\n");
else
printf("\nGrand winner -> Tie\n");
return 0;
}
