Thread: lotto program in c

Write an algorithm + a program in C that will allow us to play the “LOTTO
GAME”. For the purpose of the presentation of the assignment, you must be
able to show some winning outcomes (i.e. no randomness).
Every Saturday a draw is organized on TV. The “LOTTO GAME” is played as
follows:
Six numbers between 1 and 40 inclusive are generated at random. If a number
has been generated it is not generated a second time. A player can bet any six
numbers between 1 and 40 inclusive. The cost for each bet is MRs 20. A player
can bet as many times as he wishes for each draw. If the player gets all the six
numbers correct (the order is not important) he wins the jackpot. If more than one
player wins the six correct numbers the jackpot is shared equally among them.
The program should be able to record all the players, their bet and the total bet.
For five, four and three correct (again order is not important) betting consolation
prizes are awarded. Obviously as the number of correct numbers decreases the
number of potential winners increases and the prizes decrease also. You should
make use of functions in your program.
Each time the game is played a completely new and random set of six
numbers between 1 and 40 inclusive are generated.


this my code which i wrote

now am not able to stop duplicate of number in a single go
and am not able to write the code for the payment
example if a player win the jackpot the amount of money he wins depending on the number of games he play

thank you for looking in my program.
can you please write the code for me..
its been a month since am trying to write the program
am going mad with the code..
i have to return my project in 2 days..
can you please write the code for me..

thank you.

Code:

#include <stdio.h>
#include <stdlib.h>
#include<conio.h>
//Prototype
char randomNums(char * x, char y)
{
          char z;
           for(z=0;z<=6;z++)
           if(x[z]==y)
          return !0;
           return 0;
}


//Start main
int main(void)
{
          //Declare variables
            char r1[6], r2[6];
            char i,j;
            char num;
             char * l;
           //Enter numbers and check conditions
            for(j=0, l=r1;j<2;j++)
            {
            do{
                  num=0;
                  //Enter input
               printf("\nEnter six numbers[Between 1 and 40]:\n");
               for(i=0;i<6;i++)
               {
                     scanf("%d",l+i);
                     if(*(l+i)>40 || *(l+i)<1) num = !0;
               }
               printf("\n");
               //Check condition
               if(num)
               {
               printf("Entered range numbers wrong. So give only between 1 and 40 .\n");
         }
       } while(num);
      l=r2;
   }
   for(i=0;i<6 && randomNums(r1,r2[i]);i++);
   {
         if(i==6)
         {
                  //Display the output
                  printf("YOU WON THE JACKPOT\n");
         }
         else
         printf("Sorry..Better luck next time...\n");
         getch();
   }
}

this one is my own program
what about helping me in this one

And U know what, the amazing fact is that this person is in my class..!

Thanks for showing him the right way..
