Thanks man!

Man, sometimes I wonder about the people here... 
Have you looked into StrFormatByteSize64(...)?
Peace!

StrFormatByteSize64 isn't defined in the SDK on my machine for one reason or another.
Thanks for the pointer tho!

Your SDK and/or your MSDN Library is severely out of date - this function is available for use with VC++ 6.0, so even the last version of MSDN Library that integrates with it (which is a few years old) has it.
Note that this function became available with IE 5.0, so you need to have the _WIN32_IE value #defined to 0x0500 or greater for it to become visible. Lookup that identifier/macro if you do not know how to set it correctly.
Peace!

Yeah whatever. So I'm the last one that hasn't memorized all the APIs.
Thanks for that. I know I'll forget it later but I'll remember its existence!
Tidbits like that are the only reason I'm here
Peace!

I have having a bit of trouble, i need to write a program that converts fahrenheit to celsius (i can do the function for this part) but it needs to start with a loop that first prompts the user to "Enter Temperature:" and then stores the value entered into the array which is supposed to be no more than 50. I am having issues with how to input data into the array starting at 0 and keep going up 1 (all I can do is input data directly to myarray[50], but I want the user to input data and it be entered into the array like
enter data one > put in array[0]
enter data 2 > put in array[1]
The program also has to ask the user if they want to keep entering data by pressing 1, or stop by pressing 0. The program then has to display how many arrays there are of temperatures (not the value of them, just how many there are). Please help!! This is what I have so far, any help greatly appreciated.
// Computer Lab test.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;
// call this function to convert celsius to fahrenheit (function name is convert)
double
convert(double celsius){
double fahrenheit = ((9.0/5.0) * celsius) + 32;
return fahrenheit;
};
int _tmain(int argc, _TCHAR* argv[])
{
double myarray[50];
int flag;
flag =1;
while (flag==1)
{
// loop
cout << "Enter Temperature Reading:";
cin >>myarray[50]
;cout << " Enter 1 to input more values, 0 to stop";
cin >>flag;
}
return 0;
}

You are off to a good start. I see what you need, but there is a practice around here not to do homework for students.
So you tell me what it does so far, and more importantly what still needs to be done.

No problem, I understand and I hope I can learn through my errors. So far my program I think stores a temporary function at the start that converts any value of number entered into a double fahrenheit and returns it to another double celsius.
I stored that there just for formula's sake, and haven't implemented it or really know how to use it yet.
Then i think in this part I have correctly made an array of 50 doubles called myarray. Then i have made an int value flag that is in place of if the user puts a 1 or 0 to continue/stop the program. I want to be able to make an array that is assumed to be less than 50 values, and then the user to keep entering values until done, but I think I have it setup wrong is it just storing the values inputted into myarray[50] only? Do I have to seperatly do myarray[0], myarray[1], etc each time or is there some other loop i can make that can tell the program to keep entering values starting from [0] until when the user wants to stop. Then it should print out how many arrays there are rather than values in them. I just can't figure out how to stop the array and have the values only how many the user inputed, not all 50. Any help greatly appreciated thanks.

You're going to the same spot each time. Use a variable here.

if i make another variable, say i.. and define it like
int i
i=0
(not sure if this is right)
for i=0, i<50, i++
{
// cout "Enter Temperatures";
cin >> myarray[i]
does that work better?

Probably, but you should surround your code snippet with <pre> tags and replace angle brackets with their non-translated version (see the buttons above the smileys).

ok thank you. If i do use this and user myarray[i] as the user input, will this put data into 0-49 of the array , or until the user wants to stop?

Yes.
Why not use one of the STL containers (e.g., vector, list) instead? That way, just enough room is allocated.

haven't covered that much so we didn't have it mentioned as part of the project. I will look into them and post if I have any problems, thanks.

That's fine. I found it better to know how to do it the "hard" way first. Then when I started using MFC (and some of STL), I understood it a lot better.

An AV error is usually the result of trying to access memory that is not valid. Given the address shown, I would guess that you had an invalid pointer (or reference if using DLLs w/VC6), or a pointer that was once valid but is no longer (like by double-freeing or trying to use an allocated resource that was previously released).
To debug it, crash it under the debugger to see what variable is being used that caused the crash, and then track its use to determine where it has gone bad. Some situations like buffer over-runs or under-runs can also cause problems like this, because you "step on" the value of a pointer/reference causing a crash when you try to use it.

I found a program in C++ which uses this library, but my program doesnt recognize this library. Does someone knows other library to replace it?
|
|
|
|

I don't think the library exists any more. Try using that other one.
