    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
    lottery
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include<string.h>
    #include<ctype.h>
    #include<time.h>
    
    
    void computerGenerator();
    void winningNumbers();
    void inputstring( char *inputptr );
    void printarray(int * arrpt);
    void playChoice();
    void guess();
    void ending();
    
    
    char inputarray[512];
    char *inputptr = inputarray;
    
    
    int main()
    {
    
    
       char start;
       srand(time(NULL));
       int counter=0;
       char choice;
       int numPlay=0;
       int lotto[6][5];
       int r, c;
    
    
       printf("                 Welcome to the lotto game!!\n");
       printf("                 ------- -- --- ----- ------\n\n");
       printf("This game asks you to pick six numbers or if you prefer\n");
       printf("quickpick and then prints the winning number in ascending order\n\n");
       
       printf("\tAre you ready to start?(y/n)  ", &start);
       scanf("%c", &start);
       fflush(stdin);
    
    
         if (start == 'y')     // begin if "yes"
         {
             system("cls");
             printf("How many games would you like to play? \n");
             scanf("%d", &numPlay);
             fflush(stdin);
             system("cls");   // clear screen
    
    
             printf(" Would you like to chose your own numbers, or are you lazy and want\n");
             printf(" quick pick instead? \n\n Enter U for user input or Q for quickpick: ");
             scanf("%c", &choice);
             fflush(stdin);

       printf("\n");

    void guess()
    {
        int play[6]={0};
        printf("Enter the six numbers you want to play\n");
        printf("Type them in separating by a space\n");
    
    
        inputstring( inputptr );
        system("CLS");
    }
    
    
    void ending()
    {
         int iochar;
         printf("\nYour hand-picked numbers are:  ");
         printf( inputarray );
         printf("\n");
    }

    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

    For the numbers:
    Lotto drops all numbers in a mill in order to scramble them. You can do the same by
    (1) Make an array of size 40 and initialise its elements from 1 to 40 inclusive.
    (2) Use the "rand()" function to generate two indices between 0 and 39 inclusive, and swap the contents associated with these indices.
    (3) Do step (2) several times.
    (4) Consider the first six elements of the array as the winning lotto sequence.

    Or you could just stop pretending you can program and just admit you're another useless copy/paste programmer who thinks they can get by with google searches and sob stories.

    Yet another lottery program
    Apart from throwing in a few random blank lines, the code is the same.

    So how about actually making your OWN program, instead of trying to pass off someone else's work as your own.

    At least then what you post will be your OWN effort, within the limits of your OWN understanding.
    If you're not prepared to do this, just go back to your tutor and tell them you want to drop the course (before you get kicked off it anyway for either cheating or incompetence).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    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;

                      //Enter input

             }
           } 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

    Of course. Firstly, try to implement what I described in post #2. Then, I believe everything will become clearer.
