    Arrays With Stock Prices!

    Hi I'm still a little uncertain with all my arrays and functions so I was wondering if before I went any furture with this project if you guys could tell me if I'm going the right direction.

    P.S. Sorry about all the questions I have a massive project due for the next three weeks lol.

    This is only the very beginning of this project so if you could could just give me some tips/advice i'd really appreciate it. Thanks!

    This code is for the first report I must do... out of four lol. Here the question then my code as of now.

    I. The Analysis
    Report 1

    Write functions to do the following:

    Determine the number of days on which the price of the first stock exceeded the price of the second stock.

    Determine the number of days on which the price of the second stock exceeded the price of the first stock.

    Determine the number of days on which the price of the stocks was the same.

    Display the results with appropriate labels.



    Code:
    //Doug Miller
    
    //Project #4 - Working with stock information and organizing them.
    
    #include <stdio.h>
    
    #include <conio.h>
    
    #include "util.h"
    
    
    
    
    #define MAX_STOCKS 20
    
    float stock1[MAX_STOCKS] = 
    {34.25,40.50,36.50,40.00,
    30.25,30.25,35.50,36.00,
    34.25,37.00,34.00,35.00,
    36.25,34.25,40.50,41.50,
    41.50,40.00,36.50,34.50};
    
    
    float  stock2[MAX_STOCKS] = 
    {40.25,38.50,34.50,33.50,

    Seems fine to me, except that secondGreater(stock1, stock2) is equivalent to firstGreater(stock2,stock1)

    Well it seems OK so far - does it work?

    It's a little over spaced vertically (too many blank lines) for my taste.
    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.

    It won't cause an issue...but the reason you write functions is to modularize your program and prevent you from re-writing code...so if you're okay with writing all the needless code, then it's fine.
