    Help

    Hi, i was wondering if there is anyone out there kind enough to do the following code for me. i have no idea where to start since i dont know much about arrays.This is what the program should do:

    1) Prompt for and then accept 10 floating point values from the
    user.
    2) Store these values in an array.
    3) Pass the array to a procedure which prints out the values to
    4 decimal places in a numbered fashion (i.e like line numbers).
    4) Pass the array to a function which returns the maximum value.
    5) The returned maximum value is printed out in scientific or
    exponential format along with a suitable heading.


    Can someone please write the whole code???
    This is only a test code so its just so i get an idea, the main code is totally different
    Thanks

    No-one here is going to do your homework for you but this should answer your first question:

    Judging from your previous topics and your attitude of cheating and attempting to get homework done for free, I'm going to...:

    • ...call you a cheating dirtbag.
    • ...tell you to get help somewhere else.
    • ...tell you I hope you fail a course you don't deserve to pass.
    • ...point you towards my signature.
    • ...suggest that you learn the C language and how to apply it yourself, since we can't spoon-feed you throughout life.
    • ...tell you to actually write code and only ask for help when you actually need it and only under circumstances where it is permissable.


    OK. Try from there.

    In reply to MacGyver, if you dont want to help, you dont have to. you dont need to call me a dirtbag you can keep the comments for yourself.
    Anyway i have done a bit of a work on it and compiles and runs and it does wat it is suppose to, but it doesnt print out in a scientific manner i dont know how to do that...
    Here is the code so far:
    [code


    //This procedure takes the array and prints out
    /

    //1. "print 10 numbers"

    print_array(number);

    fprintf(output,"The MAXIMUM value of your entered numbers is %lf\n",min(number));

    }

    [/code]

    It also does not print out to 4 decimal places. i know i have to truncate but how???

    I think this is how you print a float to 4dp using printf:
    Code:
    printf("%0.4f", num);

    A question like this will get you a MacGyver-type response, especially given that's its not the first time you've been warned about things like this.

    So you went from helpless to finished in under 4 hours?
    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.

    He wasn't calling you a dirtbag, he was projecting possible responses. Perhaps he should be a crystal ball engineer

    When they design courses they usually design them for the students not for the internet

    PS. This isn't a codefarm (How cunning of me, I made up a word deriving from renderfarm)

    In this case, I was actually calling him that.

    Case in point, previous topic of his, he said this:

    Any help would be greatly appreciated

    Thank you
    There is no doubt in my mind this moron cheats at his assignments given his begging for solutions. Salem pointed out how the guy all of a sudden managed to write a solution after asking us to do the entire thing for him. I don't think any of us really believe he's that good to sit down and figure it all out. I personally think he stole or borrowed the code from someone (or more likely a host of people from his class).

    It's a good thing I don't know his professor/teacher/instructor, but on the flip side, I would say that he will most likely fail the tests, since he is apparently unable to think and code on his feet if he needs to copy code in this manner. Even if he gets a degree, I doubt he'd last long in a real programming position.

    Hopefully, when he hands in two different assignments, written by two different people, his tutor will spot the sudden change in style and bounce his cheating ass out the door.

    Don't say that, he'll ask you to sit the test too.

    Hopefully his whoever will ask them to explain 'his' code, perhaps it's time to severely obfuscate homework answers or make them so inefficient it's ridiculous.

    The answer is actually,
    Code:
    #include <stdio.h>
    #include <string.h>
    #include <math.h>
    #include <ctype.h>
    #include <stdlib.h>
    
    void main(void)
    {
        float * arr;
        char in[10];
        char i;
    
        memset(i, 0, 1);
    
        arr = malloc(pow(10,sizeof(float)));
    
        for(; i < 10; i++)
        {
            gets(in);
            sscanf(in, "&#37;f", &arr[i]);
        }
        
        
        return;
    }
    
    void printa(float * somethingReallyLongAndStuff)
    {
        char z;
        char i;
        
        memset(z, 0, 2);    /* lol */
    
        for(; z < 10; z++)
         printf("%f\n", somethingReallyLongAndStuff[z]);
    
        return;
    }
    etc in that fashion, theres a lot more rules you could break, and potentially predictable undefined behavior to exploit
