    I can't do the commands

    Hi!
    I'm trying to create a 2-day restaurant program, but I can't get the program to open the table when I press button 1. To give the commands
    (1 ° insert table number 2 ° open table) and if the table is occupied, show ": this table is not free. Choose another!"
    The free table matrix (item = -1) and whether it is occupied (item = 0).
    Code:
    #include <stdio.h>#include <conio.h>
    
    
    
    
    int main ()
    {
    internal item [8] [5], i, j;
    int table, op,vacancy
    float value [8] [5];
    cash float = 0;
    char err = 0;
    
    
    
    
    printf ("\ n");
    {
    printf ("| * -------------------- Welcome to the restaurant! ------------------- - * | \ n ");
    printf ("\ n");
    
    
    {
    printf ("[1] Open table \ n");
    printf ("[2] Launch expense \ n");
    printf ("[3] Close the table account \ n");
    printf ("[4] Check the Cashier \ n");
    printf ("[0] Exit \ n");
    printf ("\ n Choose an option:");
    scanf ("% d", & op);
    }
    
    
    printf ("Enter the table number:");
    scanf ("% d");
    
    
    }
    
    
    
    
    return 0;
    }

    internal, item and cash are not valid C keywords.
    In scanf you shouldn't have a space between % and d
    You need to implement the functionality of the menu items.

    Before you attempt to program in C, you first need to study a good book on the C Programming Language, cover to cover, and do all the exercises at the end of each chapter! Choose one of the three listed below:

    C Programming, A Modern Approach
    Author: K. N. King

    C Primer Plus, 6th Edition
    Stephen Prata

    C How to Program, 8/e
    Deitel & Deitel

    You also need to compile with the error/and warnings turned on, and turned up to see all the warnings.

    conio.h is a non-standard Windows only header file.

    Please also choose an indent style.
