    Exclamation 2Dimensional Arrays-find lowest, largest, and total of each column HELP!!!!

    Hey everyone!
    So i posted about this assignment earlier, but i had a completely different problem, so I decided to make a new thread!

    So, here is the assignment:

    Code:
    Project: Sales Tables
     
    The following table shows the total sales for salespeople of the ABC Manufacturing Company.
            Salesperson      Week 1  Week 2 Week 3  Week 4
        ===============  ======  ======  ======  ======
        Nguyen, Michael    25     30      45      20
        Johnson, Mary      32     30      33      29
           ...                    
    The price of the product being sold is $1985.95 (define it as a constant). 
    Write a program that permits the input of the data, up to 25 salespersons and up to 6 weeks, 
    prints a replica of the original table to the screen, and 
    writes to a file a table showing the dollar value of sales for each individual during each week along with his or her total sales. 
    Also it prints the total sales, the lowest and the highest value for each week, 
    and the total sales for the company.
    So, i have 4 functions right now: main, getNames, getSales, and calcSales.

    I'm trying to write a 5th function that will calculate the lowest and highest from each column, the total for each week, and the total for each person. Somehow, my function wont work. I tried to use a debugger but I cant find the problem..it just seems that I'm not doing my for loops correctly or something...could u please take a look at my code? THANKS!!!

    here's my code:
    Code:
    #include <stdio.h>
    
    #define INPUT_FILE_GET_NAMES "names.txt"
    #define INPUT_FILE_GET_SALES "sales.txt"

    #define MAX_COLS_NAMES 20
    #define MAX_ROWS_SALES 25
    #define MAX_COLS_SALES 6
    #define PRICE_OF_PRODUCT 1985.95
    
    //Function Declarations
    int getNames(char namesArray[][MAX_COLS_NAMES]);
    int getSales(int salesArray [][MAX_COLS_SALES], int a);
    void calcSales(int size, int numWeeks, int salesArrays[][MAX_COLS_SALES], double total[][MAX_COLS_SALES]);//, double sum[MAX_ROWS_SALES]);
    double calcHiLowTotal(int size, int numWeeks, double calc[][MAX_COLS_SALES], double total_sales[MAX_ROWS_SALES], double low[MAX_ROWS_SALES], double high[MAX_ROWS_SALES]);
    
    int main()

    Process returned 4 (0x4)   execution time : 0.290 s
    Press any key to continue.
    so the names are from the getNames function, the 4 columns of integers are from the getSales function, and the 4 columns of floats is from the calcSales function, in which I calculate the amount of sales each person made per week.

    the sales.txt is this:
    Code:
    4
    25 20 25 25
    20 22 23 22
    25 26 25 22
    30 28 25 26
    25 30 45 20

    30 10 35 32
    28 29 30 35
    15 16 15 14
    12 15 12 19
    20 24 20 18
    10 15 12 16
    32 30 33 29
    notice how the first number of this file, the number 4, is ignored when I store the .txt file into an array and print the array. Its supposed to be ignored. this number stands for the number of weeks, or columns the txt file has. it's just for our own knowledge.
    Then, the same goes for the names.txt file. it contains names, in the format of: last name, first name

    Code:
    16

    Okay, looks like you have your getXXX functions working now, which is good, but you will have to change them (don't worry, easy stuff) to get the program to print correctly. You need to remove all the print statements from the get functions. I would create a function that prints the sales data like you show above. Something like:
    Code:
    void outputSalesData(int namesArray[][MAX_COLS_NAMES], int numNames, int salesArray[][MAX_COLS_SALES], int numSales)
    That function will print the header row and the table of names/sales data.

    Beyond that, I don't know what your problem is, exactly. Once again, you need to tell us exactly what doesn't work about it. Your table of sales totals looks correct to me. At some point you need to actually print out the other statistics you calculated. The exact format depends on the assignment specifications.

    Oh, yes, my assignment requires us to make a function that prints all the data out to the screen, I just thought I would work on that later when I got all the data to print in the separate functions..but I think you're right, I'll write one right now that prints the namesArray, salesArray, and the table of sales totals.
    And i'm sorry I wasnt clrear on that!! :O
    Ok, so the problem is that when I add the printf's after each of the for loops in the calcHighLowTotal, and i make the printf's to print the low, high, total, and comp (comp is the total company sales), the function prints something totaly bogus, junks values or something. so I deleted all the printf's, so basically right now in the code that i gave you, the calcHighLowTotal doesn't print anything, only calculates.Right now, I will include only one printf that should print the lowest for each column of total sales, and you will see that somehow it won't print the right values!!

    here is my updated code, where I added the printf statement in the calcHighLowTotal function, right in the for loops that calculate the lowest for each column:
    Code:
    #include <stdio.h>
    
    #define INPUT_FILE_GET_NAMES "names.txt"
    #define INPUT_FILE_GET_SALES "sales.txt"
    #define MAX_ROWS_NAMES 25
    #define MAX_COLS_NAMES 20
    #define MAX_ROWS_SALES 25
    #define MAX_COLS_SALES 6
    #define PRICE_OF_PRODUCT 1985.95
    
    //Function Declarations
    int getNames(char namesArray[][MAX_COLS_NAMES]);
    int getSales(int salesArray [][MAX_COLS_SALES], int a);
    void calcSales(int size, int numWeeks, int salesArrays[][MAX_COLS_SALES], double total[][MAX_COLS_SALES]);//, double sum[MAX_ROWS_SALES]);
    double calcHiLowTotal(int size, int numWeeks, double calc[][MAX_COLS_SALES], double total_sales[MAX_ROWS_SALES], double low[MAX_ROWS_SALES], double high[MAX_ROWS_SALES]);
    
    int main()

       int salesArray[MAX_ROWS_SALES][MAX_COLS_SALES] = {0};
    
       double total[MAX_ROWS_SALES][MAX_COLS_SALES] = {0};
       //double sum[MAX_ROWS_SALES] = {0};
       double calc[][MAX_COLS_SALES] = {0};
       double total_sales[MAX_ROWS_SALES] = {0};
       double low[MAX_ROWS_SALES] = {0};
       double high[MAX_ROWS_SALES] = {0};

       numNames=getNames (namesArray);
       numWeeks=getSales (salesArray, numNames);
       calcSales(numNames, numWeeks, salesArray, total);//, sum);
       calcHiLowTotal (numNames, numWeeks, calc, total_sales, low, high);
    
    
    }

    }
    instead of printing the lowest for each column from the total sales table, it prints me 0.00000 as the lowest....

    here's the output i get:

    so yeah, I think the problem is somewhere in my for loops....

    You're using the calc parameter to calculate your lows and highs. That is passed in from the calc array in main, which is initialized to all zeros. Should you be passing in the salesArray or total variables instead?

    Code:
        if (a <= MAX_COLS_NAMES)
        {
     
     
            for(i=0;i<a;i++)
            {
                for(j = 0; j <= MAX_COLS_NAMES; j++)
    First of all, the number of rows in your array is MAX_ROWS_NAMES

    Second, using <= means you're running off the end(s) of your arrays.
    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.

    OMG.....YOU GUYS ARE SERIOUSLY AMAZING!!! it would take me half a day to realize that I was passing in the wrong array!! DUHH of course it would print me 0.0000 cause there are no values in the array!! So i just changed it to the total_sales array because that's the array the low and high have to take their values from so they can compare them, and NOW EVERYTHING WORKS!!!!! THANKS SO MUCH @anduril462

    and @Salem OHH yeah, I didn't even catch that mistake either! Thanks for pointing that out, i fixed it!!
    this is my output now!!

    I think I'll need help printing everything in the print to screen function!! Like, the way the table is gonna look, the orientation!
    And of course, I'll need a little help with the print to output file function too. I'll get back to you guys very soon, hope you don't mind!!

    Ok guys, I'm back, I knew it -_____- soooo, just now I realized that when I calculated the total amount of sales each person had for all 4 weeks, the amount should have been stored in a one dimensional array....and I stored it in a two dimensional array!! Now i'm trying to print the total amount of sales for each person, and the values come out to 0.000
    is it possible for me to go back to my program and change the code so the sale totals for each person are stored in a 1D array? or is that too much fuss, and there's a way to tweek something in my function? The problem is in my last function, outputSalesDataToFile, in the last for loop, where I'm trying to print the two dimensional array called "total".
    Could you please review that part of code and then my calcSales function (where i'm storing the total sales for each person in the 2D array "total") and tell me if I can change the 2D to a 1D array, and any other suggestions you might have?!

    THANKS SO MUCH!!

    NEVERMIND ACTUALLY, I FOUND MY ERROR, SO NOW I CAN PRINT THE TOTAL/PERSON.
    the only LASTT problem is that I cant print the Total Sales for each week!! I print it fine in my calcSales function, the correct values come out there (there are 4 values that come out). but when I try to print it in my last output to file function, it just prints 0.0000!!! WHY?! IS MY FOR LOOP WRONG?! I COPIED THE EXACT SAME FOR LOOP INTO MY LAST FUNCTION AND IT STILL WONT WORK!!!

    my code:
    Code:
    #include <stdio.h>
    
    #define INPUT_FILE_GET_NAMES "names.txt"
    #define INPUT_FILE_GET_SALES "sales.txt"
    #define MAX_ROWS_NAMES 25
    #define MAX_COLS_NAMES 20
    #define MAX_ROWS_SALES 25
    #define MAX_COLS_SALES 6

    for (i = 0; i < numWeeks; i++)
    {
        comp += total_sales[i];
        for (j = 0; j < numNames; j++)
        {
            total_sales[i] += total[i][j];
        }
        printf("%f   ", total_sales[i]);
    }
    Where are you printing the line in red? Because it's not to your output file.

    Also, please be careful - "comp" is not initialized in this function, and its first use adds a value to itself, resulting in a nonsense value.

    WHY?! IS MY FOR LOOP WRONG?! I COPIED THE EXACT SAME FOR LOOP INTO MY LAST FUNCTION AND IT STILL WONT WORK!!!


    Code:
    tolower(kal123456);
    Be wary of copy/pasting! It can make a lot of things go faster, but can also trip you up for a long time with subtle bugs.
