    Stuck with coding while Senior Project Due!!!!

    Hey guys, I'm an electrical engineering student who was forced to take CS1 class in order to graduate cause my school doesn't provide elective class on Summer. However I took C programing for like 2,3 years ago. I forgot most of it for lack of practicing. I would really appreciate if you guys could help me out.
    Here is what I got so far.. I"m stuck with syntax problem. "expected unqualified-id before numeric constant. Really Really appreciate if you guy help me out. Thanks..

    I attached the assignment document.


    Code:
    // Name:
    // PID: k1368475
    // Assignment: 1
    // KnightlotteryBall
    
    // Standard library declaration 
    
    #include <stdio.h>
    #include <stdlib.h>
    
    // Define numbers player and prize for matched numbers
    
    #define Played_number 6
    #define 3numbers 10;
    #define 4numbers 1000;
    #define 5numbers 10000;
    #define 6numbers 1000000;
    
        
    // Stores information for the KnightsBallLottoPlayer 
    typedef struct KnightsBallLottoPlayer {
            char firstName[20];
            char lastName[20];
            int numbers[6];
            } KBLottoPlayer;
    
    int main (void)
    {
        FILE * infile;
        FILE * outfile;
        infile = fopen ("input.txt", "r");
        outfile = fopen ("output.txt", "w");
        int i, j;
        int winners [6];
        int h;
        int* ptr;
        int tickets = 0;
    
        fscanf(infile, "%d", &tickets);
    
    struct KnightsBallLottoPlayer KBLottoPlayer[tickets];
        
        ptr =(int*)calloc(tickets, sizeof(int));
        
        for (i = 0; i < tickets; i++)
        {
            fscanf(infile, "%s", &KBLottoPlayer[i].lastName);
            fscanf(infile, "%s", &KBLottoPlayer[i].firstName);
            
            for (j = 1; j <= Played_number; j++)
            { fscanf(infile, "%d", &KBLottoPlayer[i].Played_number[j]);
            }
            }
            
            printf("Please enter the winning lottery numbers:\n");
        scanf("%d %d %d %d %d %d", &winners[0], &winners[1], &winners[2], &winners[3], &winners[4], &winners[5]);
       
    
        for (i = 0; i < Played_number; i++)
        {
            printf("%d ", winners[i]);
        }
        
        for (i = 0; i < j; i++)
        {
            for (j = 0; j < Played_number; j++)
            {

                {

    Code:
    #define 3numbers 10;
    #define 4numbers 1000;
    #define 5numbers 10000;
    #define 6numbers 1000000;
    Never put an ";" semicolon in a define statement.
    I would also not start them (define macro) with a number.

    Code:
    // Stores information for the KnightsBallLottoPlayer 
    typedef struct KnightsBallLottoPlayer {
            char firstName[20];
            char lastName[20];
            int numbers[6];
            } KBLottoPlayer;
    Code:
    struct KnightsBallLottoPlayer KBLottoPlayer[tickets];
    Do NOT reuse the identifier KBLottoPlayer twice for two different things.

    Move the first line of real code "fopen" and "fscanf" after the variable section (required by some C Compilers).
    Code:
    fscanf(infile, "%d", &tickets);

    Valid identifier does not start with number.

    Code:
    #define 3numbers 10
    #define 4numbers 1000
    #define 5numbers 10000
    #define 6numbers 1000000

    You are most likely getting the error on this line:
    Code:
    int winners [6];
    Notice the space between winners and the array size.
    1. Get rid of gets(). Never ever ever use it again. Replace it with fgets() and use that instead.
    2. Get rid of void main and replace it with int main(void) and return 0 at the end of the function.
    3. Get rid of conio.h and other antiquated DOS crap headers.
    4. Don't cast the return value of malloc, even if you always always always make sure that stdlib.h is included.

    You should indent your code and tell us what is the exact error, including which line was indicated by the compiler.

    Whitespace is not significant in this context, so if the compiler reports an error, you can report a real live compiler bug.

    What happened to your indentation?
    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.

    OP: post compiler error and post your code with line number!

    I wonder if it's because they copy/pasted some pre-crafted answer from another forum?

    There are several places where google found it, say

    @claudiu: thanks for the help. but it is ok with the space though
    @laserlight and Bayint sorry I forgot about it:
    @Salem: enum is a same way to do that
    I post 2 place to get more help. here and codecall. I dont copy and paste. I've try to do this since 2 days a go... sorry for multiple posts.
    this is the code
    I got error at line 52 "fscanf(infile, "%s", KBLottoPlayer[i].lastName);"

    You've defined a struct KBLottoPlayer but in your code KBLottoPlayer is an integer... not a struct.

    You need to allocate actual space for the structs...
    Code:
    KBLottoPlayer *Players = calloc(100,sizeof(KBLottoPlayers));
    Now you can use Players[index]->firstName etc in your code.

    Yes, taking a second look at it now, this looks so fake and stolen it is not even worth my time; and posting on more than one forum doesn't get you MORE help but LESS help, it just wastes MORE time for MORE people.

    So we use calloc instead of malloc? I went to TA at school, he suggest me change to malloc but say nothing but general thing. I've been reviewed these stuff straight up couple days o_O. Thanks.
