    So, that's the source of the steak and chicken dinner problem I've been reading about!

    To get this off to a flying start, pick one program you think is easiest, and make up pseudo code and a skeleton program for it, and post it. Be sure to mention what has you stopped from going on. Look for the logical steps you would make, if you were to solve this without a computer.

    Our mind-reading skills are over-rated, I assure you, so the more specific your questions are, the better the answers you'll receive.

    Get started ASAP, because programming in C can take longer than you'd think.

    I can programming in C real fast; it is getting the program to do what I want that takes so much time.

    In other words, testing the program takes a long time for me to do.
    I can fix it rather quickly; but, this is after using a C-Like language that caused me to pick up very bad habits.

    Hint: On writing programs, try writing the output code first using literals/constants for the user inputs.
    The output code is almost always easier to write than the input code.

    Your wedding reception dinner problem may be the same as the problem in this thread:
    How to do a math equation in c Programming

    If not, it's very close. Especially, check out my thread dated today. That has the arithmetic you need (at least one version of it, there undoubtedly are others), to solve the number of maximum steak dinners, using C.

    The algebra equations at the top of that post are just for understanding. Go to near the end to see the other (C type) equation you may be able to use.

    Don't get me wrong, that book is great for reference but poor for teaching and understanding C.
    I recommend: Teach Yourself C, Third Edition by Herbert Schildt

    I've read the Greek-translated version and it's very good! Anyway, just a suggestion.

    I can only assume that's the same Herbert Schildt of bullschildt fame. I sincerely hope it doesn't suffer the same egregious errors as C: The Complete Reference (or C: The Complete Nonsense). Maybe check out our book recommendations sticky thread for other suggestions.

    Ok... look at the problem logically... you have a 50 x 30 foot room ... each table is 4 x 8 with 3 feet between them...

    So... you are working with areas 7 feet by 11 feet for each table... now, how many can you fit along each wall?

    On the 50 foot wall you can get 4 (50/11) tables the long way or 7 (50/7) tables the short way.
    On the 30 foot wall you can get 2 (30/11) tables the long way or 4 (30/7) tables the short way.

    so...
    Placing the tables the long way of the room you end up with 4 by 4 = 16 tables
    Placing them the short way you get 7 by 2 = 14 tables.

    Now was that so hard?

    Well, I don't know... Maybe our Greek translators were smarter than him!

    Or, in all due respect... perhaps it's time for a review...

    Seeing such doubt cast upon a trusted source would send me off to verify my understanding of the disputed concepts...

    I couldn't bring myself to use the word 'wise' in that sentence.

    Hey CommonTater, thanks for the help, but do I need to show the calculation in my coding? if yes, I did this coding, I know it's long and there's a better way to make it shorter, but it won't let me run it cuz i get an error in line 55, can you please tell me if this is what I'm supposed to do and tell me what might possibly be the error.

    Code:
    // Jay Hakimi
    // COP 3223 Section 4
    // Programming Assignment #1
    // A Program to help Arup make decisions concerning his wedding
    
    #include <stdio.h>
    
    int main (void)

        int length_of_table, width_of_table;
        int space_walls_tables;
        int people_per_table;
        int max_people;
        int nlength_table, nwidth_table;
        int num_table1, num_table2, num_table3, num_table4;
        int max_table1, max_table2;
        int max_people1, max_people2;

        width_of_room = 30;
        length_of_table = 8;

        space_walls_tables = 3;
        people_per_table = 10;
        nlength_table = space_walls_tables+length_of_table;
        nwidth_table = space_walls_tables+nwidth_table;
    
        num_table1 = length_of_room/nlength_table;
        num_table2 = length_of_room/nwidth_table;
        num_table3 = width_of_room/nlength_table;
        num_table4 = width_of_room/nwidth_table;
    
        max_table1 = num_table1*num_table4;
        max_table2 = num_table2*num_table3;
    
        max_people1 = max_table1*people_per_table;
        max_people2 = max_table2*people_per_table;
    
        printf ("What are the length and width of the room?\n");
        printf ("%d feet by %d feet\n\n", length_of_room, width_of_room);

        printf ("What is the max number of people per table?\n");
        printf ("%d People\n\n", people_per_table);
    
        if (max_people1 > max_people2)
            printf ("This arrangment seats %d people\n", max_poeple1);   <----------------- ERROR
        else

    If you got an error, then surely you would say what it was. (Granted it's not going to come out and say "you misspelled your variable name", but it'll be awfully close.)

    No it doesn't .
    Pay close attention to the exact spelling in that error message. The 'o' comes after the 'e'.
